- Epidermal cell: often associated to be parenchymal cell despite tabular shape; most lack chlorophyll; in the area of the leaf and the stem, the epidermal cells secrete a waxy cuticle on top of tissue; not present in the roots; in the roots, its called root hairs
-
epidermis function
- Guard cells allow for exchange of gases
- Epidermal protect and prevent dehydration of the moisture of the plant through the waxy cuticle
- Root hairs increase SA for the absorption of water and minerals
-
epidermis location
- Found on surface of all primary plant parts’ found on surface of stems and roots

periderm characteristics

- cork: cells dead at maturity filled with lipid substance called suberin
- cork cambium: meristematic tissue that gives rise to new cork cells as cork sloughs off
-
periderm function
protection of underlying tissues
-
