Statement I is correct but Statement II is false
Statement I is correct but Statement II is false
Answers (1)
The correct option is Option 4) Statement I is correct, but Statement II is false.
Statement I is correct. Endarch and exarch are terms used to describe the position of the secondary xylem in the plant body. Endarch refers to the condition where the primary xylem is located towards the center of the stem or root, and the secondary xylem is formed towards the outside. Exarch, on the other hand, refers to the condition where the primary xylem is located towards the periphery of the stem or root, and the secondary xylem is formed towards the inside.
Statement II is false. The exarch condition is not the most common feature of the root system. In fact, the exarch condition is more commonly observed in the stem rather than the root. In the root system, the most common condition is the endarch condition, where the primary xylem is located towards the center and the secondary xylem is formed towards the outside.
Therefore, Option 4) Statement I is correct, but Statement II is false is the correct answer.
