Question

From the centre of the tree trunk to the outward the order of vascular tissue is

Answer 1

The next portion of the trunk is called the vascular cambium. The cambium is a very thin layer of living tissue which produces new phloem to its outside and new xylem to its inside.

Answer 2

Answer:

The order of vascular tissue from the centre to the periphery in tree trunks is primary xylem, followed by its secondary counterpart, with a vascular cambium, differentiating into the secondary phloem, and the primary phloem forming the periphery.

Explanation:

Monocotyledons are plants with a single cotyledon, i.e., seed leaf.
They are usually trimerous or pentamerous.

Eg. - lillies, grasses, palms, etc.

Now, to understand the vascular structure of the tree trunk, we need to know its order first -

primary xylem → secondary xylem → vascular cambium →  secondary phloem → primary phloem
(centre to periphery)

This order is in coherence with the process of differentiation of tree trunk, separated from primary and secondary growth and maturation.
