Soil Class 7 Questions And Answers Question 17.
Write about soil erosion.
Answer:
The removal of fertile topsoil by water, wind or ice is known as erosion. Plant roots firmly bind the soil. In the absence of plants, soil becomes loose. So it can be moved by wind and flowing water. So, cutting of trees and deforestation should be prevented and efforts should be made to increase the green areas.

Chapter 9 Science Class 7 Extra Questions Question 18.
Discuss the dependence of crop on soil type.
Answer:
The climatic factors, as well as the components of soil, determine the various types of vegetation and crops that might grow in any region. Clayey and loamy soils are both suitable for growing cereals like wheat and gram. Such soils are good at retaining water. For paddy, soils rich in clay and organic matter and having a good capacity to retain water, are ideal.

For lentils (masoor) and other pulses, loamy soils, which drain water easily, are required. For cotton, sandy-loam or loam, which drain water easily and can hold plenty of air, are more suitable. Crops such as wheat are grown in the fine clayey soils because they are rich in humus and are very fertile.

Earthworms breathe through their skins. The skin of an earthworm feels moist and slimy on touching. Gases can easily pass through them.

Question 16.
Give a brief description of our respiratory system with diagram.
Answer:
Normally we take in air through our nostrils. When we inhale air, it passes through our nostrils into the nasal cavity. From the nasal cavity, the air reaches our lungs through the windpipe. Lungs are present in the chest cavity.

Answer:
Class 7 Science Chapter 10 Extra Questions

Question 18.
Describe respiration in cockroach.
Answer:
A cockroach has small openings on the sides of its body. These openings are called spiracles. Internally, they have a network of air tubes called tracheae for gas exchange. Oxygen-rich air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches every cell of the body. Similarly, carbon dioxide from the cells goes into the tracheal tubes and moves out through spiracles.

Question 19.
How does breathing take place?
Answer:
Breathing involves the movement of the diaphragm and the rib cage. During inhalation, ribs move up and outwards and diaphragm moves down. This movement increases space in our chest cavity and air rushes into the lungs. The lungs get filled with air. During exhalation, ribs move down and inwards, while diaphragm moves up to its former position. This reduces the size of the chest cavity and air is pushed out of the lungs.

Question 20.
List the similarities and differences between aerobic and anaerobic respiration.
Answer:
Similarities :

  • Energy is released.
  • Carbon dioxide is produced.

Differences :

  • Anaerobic respiration does not require oxygen while aerobic respiration takes place in the presence of oxygen.
  • Glucose is completely broken down into CO2 and water in aerobic respiration but not in anaerobic respiration.

Question 21.
Why do we often sneeze when we inhale a lot of dust-laden air?
Answer:
When we inhale a lot of dust-laden air often these particles get trapped, in the hair present in the nasal cavity. Then they irritate the lining of the cavity, as a result of which we sneeze. Sneezing expels these foreign particles from the inhaled air and a dust-free, clean air enters our body.

Question 22.
Boojho has seen in television programmes that whales and dolphins often come up to the water surface. They even release a fountain of water sometimes while moving upwards. Why do they do so?
Answer:
Whales and dolphins are mammals and they have lungs to breathe. For breathing, they have to come on the surface. During moving upward, they abruptly exhale air, which results into a fountain of water.

Experiment:

Aim: To show that exhaled air is rich in carbon dioxide.
Requirements: Freshly prepared lime water, bent glass pipe and test tube.
Procedure: 2 ml of freshly prepared lime water (clear solution) is taken in a test tube. Lime water is the common name for calcium hydroxide [Ca(OH)2]. Now, with the help of a bent pipe the exhaled air from mouth is blown.

Observation: Lime water turns milky.

Conclusion: The above observation confirms that exhaled air is rich in carbon dioxide.

Water: A Precious Resource Class 7 Extra Questions and Answers Science Chapter 16

Water: A Precious Resource Class 7 Questions And Answers Question 14.
How is increasing population responsible for depletion of groundwater?
Answer:

  • Increasing population creates demand for construction of houses, shops, offices, roads and pavements. This decreases the open areas like parks and playgrounds. This, in turn, decreases the seepage of rainwater into the ground.
  • Moreover, a huge amount of water is required for construction work. Often groundwater is used for this purpose.
  • So, we are not only consuming more groundwater, but we also are allowing lesser water to seep into the ground. This results in depletion of water table.

Extra Questions On Water Class 7 Question 15.
Explain the factors responsible for the depletion of water table.
Answer:
There are three main causes of depletion of water table:

  • Increasing population: Increasing population creates demand for construction of houses, shops, offices, roads and pavements. This decreases the open areas like parks and playgrounds. This, in turn, decreases the seepage of rainwater into the ground. Along with consumption of water increases.
  • Increasing industries: Water is used by all the industries. The number of industries is increasing continuously. Water used by most of the industries is drawn from the ground.
  • Agricultural activities: These irrigational systems may suffer from lack of water due to erratic rainfall. Therefore, farmers have to use groundwater for irrigation. Population pressure on agriculture forces increasing use of groundwater day by day. This results in depletion of water table.

Class 7 Chapter 16 Science Extra Questions Question 16.
Explain how groundwater is recharged?
Answer:
The rainwater and water from other sources such as rivers and ponds seeps through the soil and fills the empty spaces and cracks deep below the ground. The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process.

Reproduction in Plants Class 7 Extra Questions and Answers Science Chapter 12

Chapter 12 Science Class 7 Extra Questions Question 16.
Describe reproduction in fungus.
Answer:
The fungi on a suitable place grow from spores which are present in the air. When spores are released they keep floating in the air. As they are very light they can cover long distances.

The spores are asexual reproductive bodies. Each spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and buy humidity. So they can survive for a long time. Under favourable conditions, a spore germinates and develops into a new individual.

Extra Questions For Class 7 Science Reproduction In Plants Question 17.
Explain the method of reproduction in yeast with the help of a diagram.
Answer:
Yeast is a single-celled organism which reproduces by budding. When it gets sufficient nutrients, a small bulb-like projection starts coming out from it which is called a bud. The bud gradually grows and gets detached from the parent cell and forms a new yeast cell. The new yeast cell grows, matures and produces more yeast cells. Sometimes, another bud arises from the bud forming a chain of buds. If this process continues, a large number of yeast cells are produced in a short time.

Class 7 Chapter 12 Science Extra Questions Question 18.
What do you think will happen if all seeds of a plant were to fall at the same place and grow there?
Answer:
If all seeds of a plant were to fall at the same place and grow there, then there would be severe competition for sunlight, water, mineraLs and space. As a result, the seeds would not grow into healthy plants.

Question 19.
Describe the different methods of asexual reproduction. Give examples.
Answer:
Various methods of asexual reproduction are :
(i) Vegetative propagation: It is a type of asexual reproduction in which new plants are produced frorìi roots, stems, leaves and btids. Since reproduction is through the vegetative parts of the plant, it is known as negetative propagation. rose, sugarcane.

(ii) Budding: Here, the small bulb-like projection comes out from body of an organism is called a bud, which gradually grows and gets detached from the parent cell and forms organism, e.g., yeast. The new yeast grows, matures and produces more yeasts.

(iii) Fragmentation: This type of reproduction is common in algae. When water and nutrients are available, algae grow and multiply rapidly by fragmentation. An alga breaks up into two or more fragments. These fragments or pieces grow into new individuals. This process continues and they cover a large area in a short period of time.

(iv) Spore formation: The spores are asexual reproductive bodies. Each spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity. So they can survive for a long time. Under favourable conditions, a spore germinates and develops into a new individual. Plants such as moss and ferns also reproduce by means of spores. Fungi too reproduce by spore formation.

Reproduction in Plants Class 7 Extra Questions and Answers Science Chapter 12

Question 20.
Explain what you understand by sexual reproduction.
Answer:
Sexual reproduction: It is a type of reproduction in which two different parent cells (male and female) are required. In this type of reproduction, a male and a female gamete fuse to form a zygote. The process of fusion of male and female gametes (to form a zygote) is called fertilisation.

The zygote develops into an embryo, while the triploid endosperm (one male cell plus two female cells) and female tissues of the ovule give rise to the surrounding tissues in the developing seed. The ovary, then grows into a fruit, which surrounds the seed(s). The seed contains an embryo enclosed in a protective seed coat.
In sexual reproduction, new plants are grovn from seeds.

Question 21.
Explain the difference between self-pollution and cross-pollination.
Answer:
If the pollen lands on the stigma of the same flowers it is called self-pollination.
When the pollen of a flower lands on the stigma of another flower of the same plant, or that of a different plant of the same kind, it is called cross-pollination.

Question 21.
How does the process of fertilisation take place in flowers?
Answer:
After pollination, the anther settles on the stigma of flower, which compels the formation of pollen tubes to the ovules. The male gamete present in the pollen grain moves through the pollen tube and fertilises the ovum present in the ovule, i.e., fertilisation takes place. The fertilisation leads to the formation of zygote which later develops into an embryo.

Question 22.
Describe the various ways by which seeds are dispersed.
Answer:
Seeds and fruits of plants are carried away by wind, water and animals.
(i) Winged seeds such as those of drumstick and maple, light seeds of grasses or hairy seeds of aak (Madar) and hairy fruit of sunflower get blown off with the wind to faraway places.

(ii) Some seeds are dispersed by water. These fruits or seeds usually develop floating ability the form of spongy or fibrous outer coats as coconut.

(iii) Some seeds are dispersed by animals, especially spiny seeds with hooks which get attached to the bodies of animals and are carried to distant places. Examples are Xanthium and Urena.

(iv) Some seeds are dispersed when the fruits burst with sudden jerks. The seeds are scattered far from the parent plant. This happens in the case of castor and balsam.

Write about excretion in aquatic and land animals.
Answer:
The way in which waste chemicals are removed from the body of the animal depends on the availability of water. Aquatic animals like fishes, excrete cell waste in gaseous form (ammonia) which directly dissolves in water. Some land animals like birds, lizards, snakes excrete a semi-solid, white coloured compound (uric acid). The major excretory product in humans is urea.

Extra Questions On Transportation In Plants And Animals Question 15.
Describe the excretion in humans.
Answer:
Kidney is the most important organ of excretion in humans. The mechanism to filter the blood is done by the blood capillaries in the kidneys. When the blood reaches the two kidneys, it contains both useful and harmful substances. The useful substances are absorbed back into the blood. The wastes dissolved in water are removed as urine.

From the kidneys, the urine goes into the urinary bladder through tube-like ureters. It is stored in the bladder and is passed out through the urinary opening at the end of a muscular tube called urethra. The kidneys, ureters, bladder and urethra form the excretory system.

Transportation in Animals and Plants Class 7 Extra Questions and Answers Science Chapter 11

Question 16.
How is water absorbed in plants?
Answer:
Plants absorb water and minerals by the roots. The root have root hairs. The root hairs increase the surface area of the root for the absorption of water and mineral nutrients dissolved in water. The root hairs are in contact with the water present between the soil particles.
Transportation in Animals and Plants Class 7 Extra Questions and Answers Science Chapter 11 2

Question 17.
How is water transported in plants?
Answer:
Plants have pipe-like vessels to transport water and nutrients from the soil. The vessels are made of special cells, forming the vascular tissue. The vascular tissue for the transport of water and nutrients in the plant is called the xylem.

The xylem forms a continuous network of channels that connects roots to the leaves through the stem and branches and thus transports water to the entire plant. The process of osmosis and transpiration to helps in movement of water in plants.

Question 18.
What is blood? What is its function?
Answer:
Blood is a fluid which flows in blood vessels.
Functions :

  • It transport substances like digested food from the small intestine to the other parts of the body.
  • It carries oxygen from the lungs to the cells of the body and vice-versa in case for CO2.
  • It also transports waste for removal from the body.

Question 19.
Why is transport of materials necessary in a plant or in an animal? Explain.
Answer:
Transport system is necessary in plants and in animals. In plants, water and minerals are transported from roots to leaves so that they may prepare food. The prepared food is transported from leaves to all parts of the plant. If there were no transport system in plants, the leaves would not be able to prepare food and all the parts of plants would not be able to survive without food and hence plants would die.

In case of animals, oxygen and food is transported to all parts of the body due to which oxidation of food takes place there and energy is released. Also, the waste products produced in the process of respiration are transported to their respective organs so that they may be excreted. In the absence of transport system, animals including humans would not be able to get energy and get rid of waste. So. their survival would not be possible. Thus, it is clear that transport system is necessary in plants and in animals.

Question 20.
When a person suffers from chest pain, the doctor immediately takes an ECG. Visit a doctor and get information about ECG. You may even lookup an encyclopaedia or the internet.
Answer:
An electrocardiogram (ECG or EKG abbreviated from the German Elektrokardio gram) is a graphic produced by an electrocardiograph, which records the electrical activity of the heart over time. Analysis of the various waves and normal vectors of depolarization and repolarization yields important diagnostic information. It guides therapy and risk stratification fo heart patients.

It helps detect electrolyte disturbances. It allows for the detection of conduction abnormalities.
It is used as a screening tool for ischemic heart disease during a cardiac stress test. It is occasionally helpful with non-cardiac In 1856 Koflicker and Mueller discovered the electrical activity of the heart when a frog sciatic nerve/gastrocnemius preparation fell onto an isolated frog heart and both muscles contracted synchronously.

Alexander Muirhead attached wires to a feverish patient’s wrist to obtain a record of the patient’s heart at while studying for his DSc (in electricity in 1872 at St Bartholomew’s Hospital This activity as directly recorded and visualized uiri Lippniann capillary electrometer by the British physiologist John Burdon Sanderson. The first to systematically approach the heart from an electrical point-of-view was Augustus Wailer, working in St Mary’s Hospital in Paddington, London. His electrocardiograph machine consisted of a Lippmann capillary electrometer fixed to a projector. The trace from the heartbeat was projected onto a photographic plate which was itself fixed to a toy train.

This allowed a heartbeat to be recorded in real-time. In 1911 he still saw little clinical application for his work. The breakthrough came when Willem Einthoven, working in Leiden, The Netherlands, used the string galvanometer invented by him in 1901, which was much more sensitive than the capillary electrometer that Wailer used.

Einthoven assigned the letters P, Q R, S and T to the various deflections, and described the electrocardiographic features of a number of cardiovascular disorders. In 1924, he was awarded the Nobel Prize in Medicine for his discovery.
