Detailed explanation-3: -The epidermis is the protective outer layer of clonally related cells covering all plant organs. It is composed of a number of specialised cell types which differentiate from the basal epidermal cell in adaptively significant frequencies and patterns.
Detailed explanation-4: -A strong, stiff nonliving layer outside the cell membrane; in plants, made of cellulose. It supports and protects the cell membrane. nucleolus. Small dark area in the nucleus where ribosomes, RNA and proteins are made.
