just like any other cell membrane it holds the cell together, and controls what gets in and out of the cell!
Because the cells on the outer layer are dead, so they come off easily.
The outer layer of the skin, called the epidermis, is mostly made up of dead skin cells called keratinocytes. However, the deepest layer of the epidermis contains living cells that are responsible for producing new skin cells.
The outer layer of the hair shaft is called the cuticle. It consists of overlapping layers of thin cells that help protect the hair strand and give it its strength and flexibility.
The outer surface layer of cells in plants is called the epidermis. In animals, the outermost layer of cells is called the epithelium. Both serve as protective barriers, regulate the exchange of substances, and provide a first line of defense against pathogens.
The regenerative layer of the epidermis is called the stratum basale. It is the deepest layer of the epidermis where new skin cells are formed through cell division. These new cells then migrate upwards to replenish the outer layers of the epidermis.
Because the cells on the outer layer are dead, so they come off easily.
because cheek cells are part of an animal cell so it cannot be used and it is specialised whereas stem cells are part of a planet cell so it can be used a lot of times and it is not specialised
The cells found at the outer layer of your skin (e.g. on your arm) are dead. It's easier to get a good look at the cell of the mucous membranes.
The outer layer of the skin, called the epidermis, is mostly made up of dead skin cells called keratinocytes. However, the deepest layer of the epidermis contains living cells that are responsible for producing new skin cells.
The outer part of the leaf is called the cuticle. It is a waxy layer and does not comprise of live cells. It's function is to prevent the leaf from desiccation (drying out).
The outer portion of the cell wall is primarily composed of a layer called the extracellular matrix (ECM) in animal cells, which provides structural support and facilitates communication between cells. In plant cells, the outer layer consists of cellulose, hemicellulose, and pectin, forming a rigid structure that helps maintain shape and protect against mechanical stress. In bacteria, the outer layer can include lipopolysaccharides and proteins, contributing to the cell's integrity and defense against environmental factors. Overall, these outer portions are crucial for maintaining cell structure and function.

The epedermis, the outer and the thinnest layer of your skin! :)

The outer layer of the hair shaft is called the cuticle. It consists of overlapping layers of thin cells that help protect the hair strand and give it its strength and flexibility.
The outer non-living layer of plant cells is called the cell wall. It provides structural support and protection to the cell, as well as helps regulate the movement of substances in and out of the cell.
