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.

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.

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.

Extra Questions For Class 7 Science Chapter 11 Question 14.
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.

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.

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.

Electric Current And Its Effects Extra Questions Question 12.
Write construction and working of an electric bell.
Answer:
Construction: It consists of a coil of wire wound on an iron piece. The coil acts as an electromagnet. An iron strip with a hammer at one end is kept close to the electromagnet. There is a contact screw near the iron strip.

Working: When the iron strip is in contact with the screw, the current flows through the coil which becomes an electromagnet. It, then, pulls the iron strip. In the process, the hammer at the end of the strip strikes the gong of the bell to produce a sound. However, when the electromagnet pulls the iron strip, it breaks the circuit. The current through the coil stops flowing.

The coil is now no longer an electromagnet. It no longer attracts the iron strip. The iron strip comes back to its original position and touches the contact screw again. This completes the circuit. The current flows in the coil and the hammer strikes the gong again. This process is repeated in quick succession. The hammer strikes the gong every time the circuit is completed. This is how the bell rings.

Class 7 Science Motion And Time Question Answers Question 18.
Write briefly about the development of pendulum clock.
Answer:
It is said that once Galileo (AD 1564-1642) was sitting in a church. He noticed that a lamp suspended from the ceiling with a chain was moving slowly from one side to the other. He was surprised to find that his pulse beat the same number of times during the interval in which the lamp completed one oscillation.

Galileo experimented with various pendulums to verify his observation. He found that a pendulum of a given length takes always the same time to omp1ete one oscillation. This observation led to the development of pendulum clocks. Winding clocks and wristwatches were refinements of the pendulum clocks.

Extra Questions Of Motion And Time Class 7 Question 19.
A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. The total distance covered by the car is:
(i) 100km
(ii) 25km
(iii) 15 km
(iv) 10 km
Answer:
Distance travelled in first 15 min
= speed × time
= 40 km/h × 15 min
= \(\frac{40 \mathrm{~km}}{\mathrm{~h}} \times \frac{15}{60} \mathrm{~h}\) = 10 km

Distance travelled in last 15 min
= speed × time
= 60 km/h × 15 min
=60km/h × \(\frac{15}{60}\) h=15 km
∴ Total distance = (10 + 15) km = 25 km.

Motion And Time Class 7 Questions Question 20.
Salma takes 15 minutes from her house to reach her school\on a bicycle. If the bicycle has a speed of 2 m/s, calculate
the distance between her house and the school.
Answer:
Speed = 2 m/s
Time = 15 min = 15 × 60’s
= 900 s.
∴ Distance = speed × time
= 2 m/s × 900 s = 1800 m
= \(\frac{1800}{1000}\)km = 1.8 km.

Question 21.
The odometer of a car reads 57,321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57,336.0 km? Calculate the speed of the car in km/mm during this time. Express the speed in km/h also.
Answer:
Odometer reading at 8:30 am = 57321.0 km
Odometer reading at 8:50 am = 57336.0 km
∴ Distance travelled = (57336.0 – 57321.0) km
= 15.0 km.

T time taken = 8:50 am – 8:30 am = 20 min
∴Speed = \(\frac{\text { distance }}{\text { time }}=\frac{15 \mathrm{~km}}{20 \mathrm{~min}}\) = 0.75 km/mm
∴ Speedinkm/h=\(\frac{0.75 \mathrm{~km}}{\frac{1}{60} \mathrm{~h}}\)
(∴ 1 min=\(\frac{1}{60}\)h)
= 0.75 x 60 km/b
= 45 km/h.

Question 22.
Can you also find the speed of the bus from its distance-time graph?
Answer:
Distance travelled = 80 km.
Time required = 10:00 am – 8:00 am =2h

= \(\frac{80 \mathrm{~km}}{2 \mathrm{~h}}\) = 40 km/h.

Question 23.
The distance between two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train.
Answer:
Distance = 240 km
Time = 4 h
∴ Speed =\(\frac{\text { distance }}{\text { time }}=\frac{240 \mathrm{~km}}{4 \mathrm{~h}}\)
= 60 km/h.

Rules of Interjections

While using interjections, we must keep in mind some very simple rules.

They are as follows:

We just add an interjection as an extra factor of strength to a sentence, without making any grammatical changes. This is to ensure that the latter can stand grammatical correct on its own, even if the added interjection is removed.
Interjections do not always have to be at the beginning of a sentence. They can appear in the middle, at the end, or anyplace else where the subject wants to interject a feeling and emotion.
In some cases, an interjection can be followed by a comma instead of the exclamation mark. This usually happens when the emotion to be expressed by the interjection if milder in nature.
In some cases, an interjection can be followed by a question mark instead of the exclamation marks. This happens when the interjection is added to an interrogative exclamation mark. This happens when the interjection is added to an interrogative sentence which parents a question or expects a response.
Interjections can find their way into fictional or artistic writing. Most often in the form of dialogue.
