FAQs on Plant Kingdom in One Shot (NCERT) - 1

Question 1

1. What is the plant kingdom?

Accepted Answer

Ans. The plant kingdom refers to a group of organisms that includes all plants. It is a major category in the classification of living organisms and is characterized by the presence of cell walls made of cellulose, the ability to perform photosynthesis, and the production of reproductive structures such as flowers, fruits, and seeds.

Question 2

2. How are plants classified in the plant kingdom?

Accepted Answer

Ans. Plants are classified in the plant kingdom based on various characteristics such as their reproductive structures, presence or absence of specialized tissues, and their form of nutrition. They are divided into different divisions or phyla, such as Bryophyta (mosses), Pteridophyta (ferns), Gymnosperms (conifers), and Angiosperms (flowering plants).

Question 3

3. What is the importance of the plant kingdom?

Accepted Answer

Ans. The plant kingdom is of immense importance to the environment and human life. Plants play a crucial role in the production of oxygen through photosynthesis, which is essential for the survival of all living organisms. They also provide food, shelter, and various raw materials for human use, such as timber, fibers, medicines, and biofuels.

Question 4

4. How do plants reproduce?

Accepted Answer

Ans. Plants reproduce through various methods. Some plants reproduce sexually, where male and female reproductive structures produce gametes that fuse to form a zygote. This can occur through pollination, where pollen is transferred from the male reproductive organs to the female reproductive organs. Other plants reproduce asexually, through processes such as vegetative propagation, where new plants are formed from the parent plant's vegetative parts, like stems, leaves, or roots.

Question 5

5. What are the major differences between gymnosperms and angiosperms?

Accepted Answer

Ans. Gymnosperms and angiosperms are two divisions of plants in the plant kingdom. Gymnosperms are seed-producing plants that do not produce flowers. Their seeds are usually borne on the surface of specialized structures called cones. On the other hand, angiosperms are flowering plants that produce seeds enclosed within a protective structure called a fruit. Angiosperms have more diverse forms and are the most dominant and diverse group of plants on Earth.
