Where is the epidermis tissue in a plant found?

Question

I'm just 13 and have a bio surprise test. This thing is not mentioned in my text. Please help!

Answer 1

The epidermis is the outer single-layered group of cells covering a plant, especially the leaf and young tissues of a vascular plant including stems and roots. Epidermis and periderm are the dermal tissues in vascular plants. The epidermis forms the boundary between the plant and the external world. The epidermis serves several functions: protection against water loss, regulation of gas exchange, secretion of metabolic compounds, and (especially in roots) absorption of water and mineral nutrients. The epidermis of most leaves shows dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions.

The epidermis is usually transparent (epidermal cells lack chloroplasts) and coated on the outer side with a waxy cuticle that prevents water loss. The cuticle may be thinner on the lower leaf epidermis than on the upper epidermis; and is thicker on leaves from dry climates as compared with those from wet climates.

Answer 2

Hey theres no epidermis in plants it is mainly found at animals and humans.

Answer 3

A quick Google search will tell you that it is the outer layer of tissue (as it is in animals as well).
