Question 12

Dermal tissue system

Answer 12

Outermost covering of the plant body Called epidermis in plants with no 2o
development
1 to many layers thick
Most cells are modified parenchyma that fit tightly together
Their shape is variable
Often have a cuticle
Cuticle composed of cutin and wax
Coats the outer surface of cells
Retards water loss and protective (antiherbivory, UV damage)
Secreted by the cells themselves
