Vascular cambium produces secondary xylem on the inner side and secondary phloem to the outer side.

Correct Option: B

Vascular cambium produces secondary xylem on the inner side and secondary phloem to the outer side.

Vascular tissues in flowering plants develop from plerome. Plerome is a central core of primary meristem which gives rise to all cells of the stele from the pericycle inward.

Correct Option: B

Vascular tissues in flowering plants develop from plerome. Plerome is a central core of primary meristem which gives rise to all cells of the stele from the pericycle inward.

Vascular bundles in monocotyledons are considered closed due to absence of cambium.

Correct Option: A

Vascular bundles in monocotyledons are considered closed due to absence of cambium.

Anatomically fairly old dicotyledonous root is distinguished from the dicotyledonous stem by position of the protoxylem. In dicot root, the protoxylem is located near the periphery of the vascular cylinder while in dicot stem the protoxylem is located near the centre of vascular bundle i.e., the xylem is endarch.

Correct Option: C

In closed vascular bundle cambium is absent between xylem and phloem.

Correct Option: C

In closed vascular bundle cambium is absent between xylem and phloem.
