The epidermis is a single-layered group of cells that covers plants' leaves, flowers, roots and stems. It forms a boundary between the plant and the external environment. The epidermis serves several functions, it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs 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. Woody stems and some other stem structures produce a secondary covering called the periderm that replaces the epidermis as the protective covering.

∙ 10y agoEpidermis cells are a protective layer covering the top and bottom of a leaf. They are a flat tightly knit together sheet about one cell layer thick. Epidermis secrete a waxy substance called the cuticle to help the plant hold in more water. Contain no chloroplasts.

How would you recognize the epidermis of a root versus the epidermis of a leaf?
The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
What is the usual functions of the epidermal hairs on a leaf?
to hold the moisture in the leaf
What is the name of leaf tissue where the stomata are found?
Epidermal tissue.
What are the hairs on the leaf of the water fern for?
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.
What is the epidermal cell that has a role in immunity and disease resistance?
Langerhans

How do you examine leaf epidermal cell?
Leaf epidermal cells are examined by making peelings of epidermal cells from both sides. Normally these peelings are stained and examined under the compound microscope.
What is the function of the root sheath?
allows the exit of hairs through the epidermal surface
What special extensions of a root's epidermal cells absorb water and minerals?
root hairs
What are epidermal cell's palisade cell's and veins part of?
Leaf
What is the name of leaf tissue where the stomata are found?
Epidermal tissue.
What are the adaptations of the leaf epidermal cell?
i dont know please can you help me
What is an epidermal cell?
An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
What are the hairs on the leaf of the water fern for?
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.
What is the protective substance that restricts water loss from a leaf?
There is a waxy layer called the cuticle that reduces evaporation from the leaf. It is produced by the epidermal cells of the leaf.
What is the epidermal cell that has a role in immunity and disease resistance?
Langerhans
