Question

Is Phelloderm formed by dedifferentiation?

Answer 1

Dedifferentiation:

The process of growth of cells in reverse, from a partially differentiated stage to a less differentiated stage within a specific lineage is known as dedifferentiation.

Phelloderm:

1. Phelloderm is known as the secondary cortex of trees.
2. It is formed from the dedifferentiated meristematic cells called cork cambium or phellogen.
3. They are a very thin layer of cells present on the inside of the cork cambium in woody plants.
4. These dedifferentiated cells can gain the ability to divide and produce cells that can later mature to perform specific functions and hence later lose their capacity to divide.
