Question
Secondary vascular tissue developes from
Solution
Secondary vascular tissue in plants develops from a type of meristem known as the vascular cambium. Here are the steps:
-
The vascular cambium is a layer of cells that lies between the xylem and phloem in the stems and roots of plants.
-
This cambium is responsible for secondary growth, or increase in thickness, in plants. It divides to produce new cells which become secondary vascular tissues.
-
When the vascular cambium divides, it creates new cells both towards the inside and the outside of the stem or root.
-
The cells that are produced on the inside become secondary xylem, which is responsible for transporting water and nutrients from the roots to the rest of the plant.
-
The cells that are produced on the outside become secondary phloem, which transports sugars and other metabolic products down from the leaves.
-
Over time, these secondary tissues accumulate and contribute to the thickening of the stem or root, forming the characteristic rings seen in a tree trunk.
So, in summary, secondary vascular tissue develops from the vascular cambium through a process of cell division and differentiation.
