In the following question, a Statement of Assertion (A) is given follo...
Statement: Corm is a highly condensed and specialised underground stem.
Reason: Corm has circular nodes.
The correct answer is option B - Both the statement and reason are true, but the reason is not the correct explanation of the assertion.
Explanation:
A corm is a type of underground stem that is highly condensed and specialized. It is an organ that stores nutrients and energy for the plant. Corms are commonly found in plants like gladiolus, crocus, and taro.
The assertion states that corm is a highly condensed and specialized underground stem, which is true. Corms are different from other underground stems like rhizomes and tubers because they have a unique structure and function.
The reason states that corm has circular nodes, which is also true. Corms have nodes that are thick and fleshy, giving them a circular appearance. These nodes are responsible for storing food reserves for the plant.
However, the reason is not the correct explanation of the assertion. The circular nodes of corms are just one characteristic of their structure, but they do not fully explain why corms are highly condensed and specialized underground stems. The condensed and specialized nature of corms is due to their function in storing nutrients and energy for the plant, enabling it to survive adverse conditions and produce new shoots during favorable conditions.
In conclusion, the assertion and reason are both true. Corms are indeed highly condensed and specialized underground stems, and they do have circular nodes. However, the reason does not fully explain the assertion, as the circular nodes alone do not account for the specialized nature of corms. Therefore, the correct answer is option B.
