The stem tubers are the swollen ends of specialised underground stem branches, which help in vegetative propagation of the plant.
Solanum tuberosum is an example of a root tuber which stores inulin as the main reserve food material.
The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Features of Asexual Reproduction:
Only single parents are involved.
The fertilization or gamete formation cannot take place.
This process of reproduction occurs in a very short time.
The organisms multiply and grow rapidly.
In this offspring produced is genetically similar.
