The value of escape speed from the surface of earth is

A

nodes are shorter than internodes

B

nodes have meristematic cells

C

nodes are located near the soil

D

nodes have non-photosynthetic cells.

Text Solution

Verified by Experts

The correct Answer is:
b
Vegetative propagation is asexual reproduction from various parts in plants. In plants, such as, sugarcane and ginger, appearance of vegetative propagules from nodes is because of presence of mristematic cells I them. Meristematic cells have the ability to divide to form new cells which can differentiate and give rise to permanent tissues.
