The skin
The cell membrane can best be compared to the skin of an organism. Just like skin, the cell membrane acts as a protective barrier, regulates the exchange of substances in and out of the cell, and helps maintain homeostasis by selectively allowing certain molecules to enter or exit the cell.
cell wall/cell membrane
Skin is a membrane because it keeps that which is within it contained. There was a cell then more cells which made tissues, so there were tissues and more tissues and this made an organ, when more then one organ works together to perform a function it is then a body system.
An organ system is made up of cells. Cells are made up of a cell membrane, a nucleus, chloroplast, cytoplasm, tissue, and a vacuole.
it is the stomach
plasma membrane proteins
No, a cell membrane is not a brain. The cell membrane is a semipermeable barrier that surrounds the cell and controls what substances can enter and leave the cell. The brain is a complex organ responsible for processing thoughts, emotions, and controlling movement in the body.
A cell membrane can be compared to a barrier or a gatekeeper. It regulates the movement of substances in and out of the cell, maintaining internal conditions necessary for the cell to function properly.
no they are to small to have a respiratory system or organ so they breath through there cell membrane
why is a cell membrane also named cell mosaic
Cell membrane
it can be compared to a castle because they both protect something the cell membrane protects the cell and everything in it and the castle protects...the inside of the castle and everything in it. you get it? p.s. is your name lexies?
