Question

For vegetative propagation, the vegetative part of the plant should have:
A. A growing plant
B. Reserve food
C. Leaf
D. Both A and B

Answer 1

Hint: Vegetative propagation is a mode of asexual reproduction in plants. This process involves only a single parent that give rise to young ones which are genetically and morphologically similar. A seed is not always required for a plant to grow. A plant can grow from other various structures of a plant known as vegetative propagules. Thes propagules can be runner, bulb, offset and sucker etc.

Complete Step by Step Answer:
Asexual reproduction takes place by meristematic cells. Meristematic cells are those cells which have the ability to divide. These cells continuously divide and differentiate leading to the formation of a new plant. Vegetative propagation can take place through adventitious roots that arise from nodes and internodes. For vegetative propagation, the vegetative part of the plant should have a growing point and reserve food material.

Hence option D is correct.

Note: There are two ways by which a plant can produce asexually from its vegetative parts:- Fragmentation ( When a plant is broken into different fragments and each fragment grows into a new organism), Regeneration ( The tissue have the ability to physiologically renew, repair or replace the old tissues with new tissues). There are two types of vegetative propagation that are natural and artificial. Natural methods of propagation include runner, sucker, rhizome whereas artificial method involves grafting, layering, cutting, tissue culture. As the characters of the parent plant, a superior variety can be produced. As vegetative propagation leads to a genetically similar population it can lead to accumulation of deleterious mutation. It is evolutionary non-advantageous as organisms will not be able to adapt to the changing environment.
