FAQs on Reproduction in Plants - Science, Class 7

Question 1

1. What is reproduction in plants?

Accepted Answer

Ans. Reproduction in plants is the process by which plants produce new individuals of the same species. It involves the formation of reproductive cells, such as seeds or spores, which develop into new plants.

Question 2

2. What are the different methods of plant reproduction?

Accepted Answer

Ans. Plants can reproduce through various methods, including sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of male and female reproductive cells, while asexual reproduction does not involve the fusion of cells and can occur through methods such as vegetative propagation or budding.

Question 3

3. How do plants reproduce sexually?

Accepted Answer

Ans. Sexual reproduction in plants involves the fusion of male and female reproductive cells. In flowering plants, the male reproductive cell, called pollen, is transferred to the female reproductive organ, called the stigma, through pollination. The pollen then travels down the stigma and reaches the ovary, where it fertilizes the ovules. This leads to the formation of seeds, which can grow into new plants.

Question 4

4. What is asexual reproduction in plants?

Accepted Answer

Ans. Asexual reproduction in plants does not involve the fusion of male and female reproductive cells. Instead, new individuals are produced from a single parent plant. This can occur through methods such as vegetative propagation, where new plants are grown from vegetative parts like stems or leaves, or through methods like budding, where small outgrowths or buds develop into new plants.

Question 5

5. What are the advantages of sexual reproduction in plants?

Accepted Answer

Ans. Sexual reproduction in plants offers several advantages. It leads to genetic variation among offspring, which increases their chances of adapting to changes in the environment. This variation also allows for natural selection to occur, leading to the evolution of new plant species. Additionally, sexual reproduction allows for the exchange of genetic material between different plants, promoting genetic diversity and enhancing the overall fitness of plant populations.
