Answer 2

"Phelloderm is a secondary meristem.

During the time of the secondary growth in stem and root, a new secondary tissue replaces the peripheral tissues.

The new secondary tissue is known as Periderm and the replaced peripheral tissues are epidermis, hypodermis and cortex. The secondary tissue Periderm is comprising of three constituents. That are-
