Epidermal Tissue System (1)

The epidermal tissue system forms the outer-most covering of the whole plant body and comprises epidermal cells, stomata and the epidermal appendages – the trichomes and hairs. The epidermis is the outermost layer of the primary plant body. It is made up of elongated, compactly arranged cells, which form a continuous layer. Epidermis is usually single- layered. Epidermal cells are parenchymatous with a small amount of cytoplasm lining the cell wall and a large vacuole.
