Question

Appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because
A. Nodes are shorter than internodes
B. Nodes have meristematic cells
C. Nodes are located near the soil
D. Nodes have non-photosynthetic cells

Answer 1

Hint:
Vegetative propagation is a asexual process to grow new plant. Nodes are the part of the plant which helps to grow new plant parts. Meristematic cells have the ability to grow new cells which turns into permanent tissues.

Complete answer:
In plants, the structures which are capable of growing new plant by the process of vegetative propagation is called as vegetative propagules. Vegetative propagules are plant parts. Some examples of vegetative propagules are: Runner, rhizome, sucker, tuber, offset, and bulb. Vegetative propagation is a type of asexual reproduction. Involvement of gametes is not necessary for the production of new plants. Meristematic cells are those cells which have the ability to divide and give rise to new cells and also permanent tissues. Nodes are present on the stem as well as roots of the plant which can hold one or more leaves as well as bud. It can grow into branches. Internodes are present between two nodes. The main function of roots is to give rise to the new plant part and meristematic cells help in this process. From the above information we have found that the appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because nodes have meristematic cells.

So, option B is the correct answer.

Note:
Runner and sucker are two vegetative propagules. Runner is the stem part which tends to grow horizontally as opposed to upright like the main stem. Buds can produce from the end of runner and develop into a new plant. Example: Strawberries. Suckers are the plants which are also called as root sprouts. Plant stems arise from buds on the base of parent plants stems or on roots. Example: apple and banana trees.
