Question:

Conjoint open vascular bundles are present in

Options:

1. stem of dicots only
2. stem of dicots and gymnosperms
3. stem of monocots and gymnosperms
4. stem of monocots only

Solution:

Conjoint open vascular bundles are present in the stem of dicots and gymnosperms. Conjoint open vascular bundles are bundles of xylem and phloem that are arranged in a circular pattern, with the xylem located towards the center of the bundle and the phloem towards the periphery. These bundles are called "open" because there is no cambium present between the xylem and phloem, meaning that they cannot undergo secondary growth. Therefore, the correct answer is option 2, stem of dicots and gymnosperms. Conjoint open vascular bundles are not present in monocots, as monocots typically have scattered vascular bundles rather than the circular arrangement seen in dicots and gymnosperms.
