The epidermis serves several functions: it protects against water loss, regulate gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.

The mesophyll can be further broken down into two layers, the palisade layer and the spongy layer, both of which are packed with chloroplasts, the factories of photosynthesis. In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light.

The epidermal cells in both upper and lower epidermis do not contain chloroplasts. Both upper and lower epidermis contain stomata. The guard cells of both upper and lower epidermis contain chloroplasts.

The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.

The epidermis of the leaf and stem of a plant is covered with the pores called stomata which regulates the exchange of gases and water vapors between the outside air and the interior of the leaf. So, the option (C), Conduction of water is not a function of the epidermis.

Amoeba is a unicellular organism.

Caulerpa taxifolia

Answer. Yak is not a unicellular organism.

Though each yeast organism is made up of just one cell, yeast cells live together in multicellular colonies. “They’re single-celled organisms, so they don’t grow to become mushrooms or anything like that.”

WBC cells are single cellular organisms without any restrictions, they move and capture the target things on their own. These cells have a movement similar to that of the unicellular organism’s amoeba, but they do not have any tendency to divide and reproduce on their own like amoeba and the paramecium does.

An amoeba (/əˈmiːbə/; less commonly spelt ameba or amœba; plural am(o)ebas or am(o)ebae /əˈmiːbi/), often called an amoeboid, is a type of cell or unicellular organism which has the ability to alter its shape, primarily by extending and retracting pseudopods.

amoeba: A single-celled microbe that catches food and moves about by extending fingerlike projections of a colorless material called protoplasm. Amoebas are either free-living in damp environments or they are parasites. bacteria: (singular: bacterium) Single-celled organisms.

Naegleria fowleri infects people when water containing the ameba enters the body through the nose. This typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. The Naegleria fowleri ameba then travels up the nose to the brain where it destroys the brain tissue.
