Question

A process of multiplication in which a fragment of the plant body functions as a propagule and develops into a new individual is called
A) Vegetative propagation
B) Sexual propagation
C) Regeneration
D) Metamorphosis

Answer 1

Hint:Unlike animals, plant tissues have the unique ability to remain totipotent. When cultured under the right conditions, many parts of a plant can start dividing and growing and undergo differentiation to form a new plant.

Complete answer:
Propagules are vegetative structures that can give rise to a new plant on being detached from the parent. The process of taking this fragment to grow an entirely new plant without sexual reproduction is known as vegetative propagation. Option A is the correct answer.

For sexual propagation, there needs to be a union of male and female gametes of the plant to form a zygote which then grows into a new plant. Option B is incorrect.

Regeneration is a process in which a lost body part grows back. In plants it refers to regrowth, repair, and replacement of damaged tissues. Shoots and roots can regenerate apical meristem if needed. Option C is not the correct answer.

During metamorphosis, an immature stage in an animal’s life cycle undergoes a series of physiological and physical changes involving differentiation such that the adult is completely different in form and function. Option D is not correct.

Hence the correct answer is option ‘A’.

Note: Vegetative reproduction is a very popular technique followed in horticulture and floriculture. In this way, the plant is grown as an exact clone of itself, so that the farmer can be sure of getting an identical crop. This technique is done with plants like potato and ginger, and even for those that do normally undergo sexual reproduction.
