The tuber of potato is a stem structure because it
The tuber of potato is a stem structure because it
Updated On: Jun 2, 2024
- contains reserved food
- possesses apical bud
- does not have root
- lacks chlorophyll
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The tuber of a potato is considered a stem structure because it possesses an apical bud. These buds, also known as eyes, have the potential to sprout and grow into new shoots, eventually giving rise to new plants. While other options may partially describe characteristics of potato tubers, none fully justify the function of apical buds correctly:
Therefore, in addition to serving multiple purposes, the most significant reason behind the presence of potato tubers is their ability to possess apical buds and potentially grow into new plants.
So, the correct option is (B): possesses apical bud.
- Option A: The tuber does indeed contain reserved food, but this characteristic alone is not exclusive to tubers as other parts of the potato plant, such as fruits or roots, can also store food.
- Option C: Contrary to the statement, tubers of potato plants can develop roots, which support the growth of the plant.
- Option D: While it is true that some stems lack chlorophyll, not all stems need to lack it; chlorophyll presence varies depending on the plant species and its environment.
Therefore, in addition to serving multiple purposes, the most significant reason behind the presence of potato tubers is their ability to possess apical buds and potentially grow into new plants.
So, the correct option is (B): possesses apical bud.

Stem - Nodes and Internodes
Underground Modification
In some plants, stems are modified to form underground structures that store food. Some examples of the underground stem are as follows:
Rhizome: They are non-green, fleshy structures that resemble roots in appearance. The presence of nodes and internodes distinguishes them from roots. When a rhizome grows horizontally, it is called Straggling Rhizome. This type of rhizome is seen in turmeric, ginger, etc. If a rhizome grows in an oblique direction, it is called RootStock Rhizome. This is found in bananas and alocasia.
Therefore it has nodes and internodes. Ginger is a stem and not a root because it has nodes and internodes. It is a rhizome, an underground modification of the stem.
