NCERT Solutions for Class 7 Science Chapter 12 - Reproduction In Plants

1. Fill in the Blanks:
(a) Production of a new individual from the vegetative parts of the parent is called __________.
Ans: Vegetative propagation

(b) A flower may have either male or female reproductive parts. Such a flower is called ________.
Ans: Unisexual flowers

(c) The transfer of pollen grains from the anther to the stigma of the same or of another flower of the same kind is known as________.
Ans: Pollination

(d) The fusion of male and female gametes is termed as_________.
Ans: Fertilisation

(e) Seed dispersal takes place by means of _____, _____and______.
Ans: Wind, insect, water

2. Describe the different methods of asexual reproduction. Give examples.
Ans: Different methods of asexual reproduction are:

b. Fragmentation: In the fragmentation method, the body of plants divides into two or more than two fragments and these fragments grow to form independent plants. Example of a plant showing a fragmentation method is algae.

c. Budding: In the budding method small bulb projects out from the yeast cell known as the bud which grows and then disconnects from the plant to create a new organism. Examples showing the budding method are yeast, hydra.

d. Spore Formation: When the bread is present in the open air, the fungi present in the bread grow. This is known as spore formation. Examples showing spore formation are ferns, fungi.

3. Explain what you understand by sexual reproduction.
Ans: Sexual reproduction is a mode of reproduction in plants. In sexual reproduction male gametes and female gametes fuse together with each other to form a zygote which grows into a new plant/organism.

4. State the main difference between asexual and sexual reproduction.
Ans: The difference between asexual and sexual reproduction is shown below.

5. Sketch the reproductive parts of a flower.
Ans: The pistil is the female part of the flower which includes stigma, style and ovary. Inside the ovary, ovules are present. Stamen is the male part of the flower which contains anther and filament. The anther contains pollen.

6. Explain the difference between self-pollination and cross-pollination.
Ans: The difference between self-pollination and cross-pollination is shown below.

7. How does the process of fertilization take place in flowers?
Ans:

• During pollination when the pollen grains reach the stigma of the flower, a pollen tube is generated where the pollen runs down through the style to the ovary.

• The pollen grains then fertilize the ovary which leads to the formation of a zygote. 

• The formation of zygotes by the involvement of male and female gametes is known as fertilisation.

8. Describe the various ways by which seeds are dispersed.
Ans: The various ways by which seeds are dispersed are:
(a) Wind
(b) Water
(c) Insects
(d) Animals
(e) Birds
The seeds which are lighter in weight and smaller in size are taken by the wind. The seeds which can float are taken by water. Seeds with spines are taken by animals and birds.
