Dermal Tissue System: The dermal tissue system makes up the outside covering of the plant. This system consists of the epidermis and the periderm. The epidermis is the protective outer layer of clonally related cells covering all plant organs. Plant tissues come in several forms: vascular, epidermal, ground, and meristematic. Each type of tissue consists of different types of cells, has different functions. The epidermis is mostly made up of flat, scale-like cells called squamous cells. Under the squamous cells are round cells called basal cells. Plant tissues: Epidermis- outer most layer, plants can have multiple layers of epidermis, do not contain chloroplast, only for mechanical protection (crushing or.
