Answer:
The correct option is D. (Two back-to-back phospholipid layers with the polar heads facing out on both sides)
Explanation:
The plasma membrane creates a barrier between the interior part of the cell and the cytoplasm. It is consisting of proteins and phospholipids and bi-layered in nature. Phospholipids are known as the main component of the plasma membrane.
Phospholipids are composed of alcohol and fatty acids and they are arranged in a specific manner. Each phospholipid molecule contains a water-hating tail that is hydrophobic in nature and a water-loving head which is hydrophilic in nature and the polar heads face the outside.
The epidermis is the remotest subcaste of cells generated from the protoderm that covers the stem, root, splint, flower, fruit, and seed sections of a factory. The moldable cuticle of the epidermis acts as a hedge against infection, water loss, and mechanical detriment.
<h3>What about epidermis?</h3>
- Botanically speaking, the epidermis is the face, single- layered caste of cells that covers a plant, particularly the flake and immature vascular plant corridor like stems and roots.
- In vascular shops, the dermal napkins are called epidermis and periderm.
- The barricade separating the plant from the outside world is the epidermis.
- Pavement cells, guard cells, and the attachment cells that compass the stomata and trichomes, sometimes known as flake hairs, are the three introductory cell types that make up the plant epidermis.
- Conical cells, a kind of trichome, are also formed in the epidermis of petals.
- The cuticle, a functional permeability barricade of the cell wall that inhibits devilish water loss and the entry of dangerous agents and pathogens into the host, is formed by the plant epidermis and serves as its primary function.
- The epidermis is the flake's outermost caste.
- On either side of the flake, the top and lower epidermis make up this caste.
- Botanists designate the undermost side as the abaxial face and the upper side as the adaxial face.
- Gas control is backed by the epidermis.

The exercise technique that helps to lengthen the muscles in order to improve the range of motion and movement is called static stretching. Static stretching also helps to improve blood flow to the muscles and prevents injuries if done before strenuous activity such as weight lifting.
