Epidermis, in botany, outermost, protoderm-derived layer of cells covering the stem, root, leaf, flower, fruit, and seed parts of a plant. The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.
Dead Epidermis refers to dead upper skin layers in humans and animals. The skin has two layers, the Epidermis (which is on the very surface) and the much thicker Dermis, which lies below and forms the main body of skin. Every so often, parts of the epidermis die and flake off, to be replaced by a new one that grows to take it's place. This is to keep the skin clean, and get rid of harmful bacteria that get trapped in the Epidermis.
epidermis
Hair, as it covers most areas of the body, if not all.
Keratin
The epidermis of a fetal pig is a thin outer layer of skin that is composed of epithelial cells. It serves as a protective barrier against the external environment and helps regulate temperature and prevent dehydration. It is less developed compared to adult pigs, but still provides essential functions for the fetus.
upper epidermis for sure>>>
plants and flowers
Coastal plants have plenty of water to absorb and transpire therefore their epidermis does not require water conservation; on the other hand non coastal plants have to conserve water hence their epidermis is thick.
The structure in the epidermis that gaseous exchange occurs in plants is through the stomata. A stomata is a tiny opening or pore in the epidermis.
Plants do not have an edpidermis because the epidermis is a layer of skin found only on animals.
It protects the inner parts of the plant
The projection of the epidermis is known as trichomes. In plants, these describe the spines, glands, thorns, and similar parts.
Plants have epidermis layers to protect against water loss, pathogens, and damage from the environment. The epidermis also contains specialized cells like guard cells that regulate gas exchange and stomata that allow for transpiration and photosynthesis.
stomata
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
Epidermis is the outermost layer in plants just like the skin. Epidermis protects the internal tissues from mechanical injury and pathogens.It also helps in exchange of gases , transpiration and other processes.Root hair present on epidermis of root help in absorption of water and mineral from soil.
