I'm trying to figure out the same question for h/w right now. do you know what the answer is?
The cell membrane regulates what enters and exits the cell by controlling the passage of molecules. It also provides protection to cell organelles by surrounding them and maintaining their internal environment.
You are describing the cell wall surrounding the cell membrane.
The outermost structure of an animal cell is the cell membrane. The cell membrane is the membrane separating the interior of the cell from the outside environment. It is made up of proteins and lipids.
Plant cells are covered by both a cell membrane and a cell wall. The cell membrane is a selectively permeable barrier that controls the movement of substances in and out of the cell, while the cell wall provides structural support and protection to the cell.
One major difference is that the cell membrane is a flexible barrier that surrounds the cell and regulates what enters and exits the cell, while the cell wall is a rigid structure located outside the cell membrane that provides structural support and protection to the cell.
the protection of a cell
For the protection
it is the outer layer of the protection of the cell . it controls what goes in and out of the cell . it contains lipids, proteins , and phosphlipids . its very important because it protects the cell from harmful bacteria and viruses .
The cell membrane regulates what enters and exits the cell by controlling the passage of molecules. It also provides protection to cell organelles by surrounding them and maintaining their internal environment.
The cell membrane is the thin layer that holds cells together. Cell membranes are used as barriers and for protection.
You are describing the cell wall surrounding the cell membrane.
The viscous layer that provides protection and lubrication for the cell membrane is known as the glycocalyx. It is composed of glycoproteins and polysaccharides that help in cell-cell recognition and protection against pathogens.
The cell membrane regulates what enters and leaves the cell and also provides protection and support.
the cell membrane.
The cell membrane is the part of the cell that provides protection.
the cell membrane.
the cell wall is totally different from the cell membrane . the main function of the cell wall is to provide support and protection for the cell.
