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:

a. Vegetative Propagation: In the vegetative propagation method growth of new plants takes place from the stem, root, or leaf of the plant. Examples of plants showing vegetative reproduction are ginger, potatoes.


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.

Asexual Reproduction

Sexual Reproduction

In asexual reproduction

a single parent takes part in reproduction.

In sexual reproduction, both the parents take part in reproduction.

In asexual reproduction, gamete formation does not take place.

In sexual reproduction, gamete formation takes place.

In asexual reproduction, the organism formed is the same as the parent.

In sexual reproduction, the organism formed is different from its parents.


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.


the reproductive parts of a flower


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

Self-Pollination

Cross-Pollination

Self-pollination is a type of pollination where the pollen from the flower reaches the stigma of the same flower.

Cross-pollination is a type of pollination where the pollen of the flower moves along with the agents of pollination and reaches the stigma of other flowers.


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.

Reproduction in Plants Class 7 PDF - Important Points

  • Modes of Reproduction: Plants reproduce through both sexual and asexual modes. Sexual reproduction involves the fusion of male and female gametes, while asexual reproduction occurs without the involvement of gametes.

  • Asexual Reproduction: Asexual reproduction in plants involves the production of new individuals from vegetative parts like roots, stems, and leaves. Common methods of asexual reproduction include budding, fragmentation, and spore formation.

    • Budding: A form of asexual reproduction in which a new organism develops as an outgrowth, or bud, on the parent organism. Budding is commonly observed in organisms such as yeast, hydra, and some plants like Bryophyllum.

    • Fragmentation: Fragmentation is a method of asexual reproduction in which an organism breaks into fragments, each of which can grow into a new individual. This process is common in organisms like algae, fungi, and some plants. 

    • Spore Formation: Spore formation is a type of asexual reproduction in which specialised reproductive cells called spores are produced by an organism. Spore formation is common in fungi, algae, mosses, ferns, and some bacteria. 

  • Sexual Reproduction in Flowering Plants: Flowers are the reproductive organs of flowering plants. They contain both male (stamen) and female (pistil) reproductive parts. The male part produces pollen grains containing male gametes (sperm), while the female part contains ovules with female gametes (eggs).

  • Pollination: Pollination is the transfer of pollen grains from the anther to the stigma of a flower. It can occur through various agents like wind, water, animals (insects, birds, bats), or even self-pollination within the same flower.

  • Fertilisation: Fertilization is the fusion of a pollen grain with an ovule, forming a zygote. After fertilisation, the ovule develops into a seed containing the embryo plant.

  • Seed Formation and Dispersal: The ovule develops into a seed after fertilisation. Seeds are dispersed through various means, such as wind, water, animals, and gravity to ensure the spread of plants to new locations.

  • Advantages of Reproduction in Plants: Reproduction ensures the continuation of plant species and promotes genetic diversity. Asexual reproduction allows the rapid multiplication of plants with desirable traits, while sexual reproduction promotes genetic variation through the mixing of genetic material.
