Question

Given below are two statements:
Statement I: Endarch and exarch are the terms often used for describing the position of secondary xylem in the plant body.
Statement II: Exarch condition is the most Common feature of the root system.
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are false.
• B. Statement I is correct but Statement II is false.
• C. Statement I is incorrect but Statement II is true.
• D. Both Statement I and Statement II are true.

Answer 1

Answer: (C)

Statement I is incorrect but Statement II is true.

Answer 2

In plants, the terms "endarch" and "exarch" are used to describe the arrangement of xylem elements in the stem. "Endarch" refers to the condition where the xylem elements develop towards the center of the stem, and "exarch" refers to the condition where the xylem elements develop towards the periphery of the stem. These terms are not used to describe the position of secondary xylem, but rather the arrangement of primary xylem.

Statement II is true, as the exarch condition is indeed more common in the root system, where the xylem elements develop outward from the center of the root.

Therefore, The correct option is (C): Both Statement I and Statement II are true.
