Question

Rhizome reproduction is observed in:
A) Solanum tuberosum
B) Ginger
C) Achyranthes
D) All of the above

Answer 1

Hint:
The rhizome is used in natural vegetative production or propagation in plants. Vegetative propagation is a type of asexual reproduction. The rhizome is a type of modification of an underground stem for vegetative reproduction.

Complete answer:
The rhizome is a modified part of the stem. They grow horizontally, but new shoots can be grown upwards. Roots and stems originated from the nodes of the rhizome. Rhizomes have short internodes. Roots emerge from the bottom of the nodes, and new shoots are generated from the top of the nodes.
Solanum tuberosum, commonly called as potato is propagated vegetatively. They are propagated vegetatively by a stem called a tuber. Potato tubers have nodes from which the new growth is observed. The new stems are called sprouts which give rise to the new potato plant.
Zingiber officinale, commonly known as ginger, is propagated vegetatively. In ginger, vegetative propagation occurs through the rhizome. In ginger, the underground stems act as the storage for the food. The terminal bud grows upward to produce the flowering shoot and the lateral buds grow out to form a new plant.
Achyranthes usually show sexual reproduction. Hence, it does not use any vegetative part rhizome for reproduction.
As per the above discussion, only ginger uses rhizome as a mode of reproduction.

Option ‘B’ is correct

Note:
Vegetative propagation is the formation of new plants from vegetative units such as rhizomes, buds, and tubers. There are different types of underground stem structures that can take part in vegetative propagation. Such as tubers, bulbs, suckers, and rhizomes.
