NEET Botany Tissue Systems MCQ Question
Which of the following statements about the vascular tissue system is correct?
The presence of cambium in vascular bundles allows for the formation of secondary xylem and phloem in dicots.
Monocot vascular bundles are capable of forming secondary tissues due to the presence of cambium.
Radial vascular bundles are characterized by xylem and phloem arranged in a concentric manner.
Sieve tube elements are nucleated cells that control the function of companion cells.
Correct Answer
Detailed Explanation
In dicotyledonous stems, the presence of cambium between xylem and phloem allows for secondary growth, making them open vascular bundles. Monocots, lacking cambium, do not form secondary tissues and are classified as closed vascular bundles.
