During secondary growth, new meristematic tissues arising in the cortical region of the stem are called
1 Phellogen
2 Phelloderm
3 Periderm
4 Phellem
Explanation:
Phellogen or cork cambium is the meristamatic tissue, which arises in the cortical region during secondary growth in dicot stems. Phellogen formed when a portion of cortex undergoes differentiation is a meristematic tissue which is a couple of thick layer. It is made up of narrow, thin-walled and nearly rectangular cells.
