Question

Primary body of the plant develops entirely from the embryo of seed. Which event is not involved in the development of primary body of a plant?

• A. Cell elongation
• B. Cell differentiation
• C. Cell division
• D. Dedifferentiation

Answer 1

The correct option is D Dedifferentiation

The primary body of the plant are those tissues or organs that have their own origin e.g.; epidermis, vascular tissues, xylem, phloem etc. Cell elongation is the process of cell expansion due to the functioning of auxin as it results in the plant growth. Cell differentiation is the formation of different parts of the plant by the maturation of cells. Cell division is the process of the division of cells which helps in the growth of plants. Dedifferentiation is the process in which cells or organs obtain their original position, it is the opposite of differentiation.

So, the correct option is 'Dedifferentiation'.
