Skin( yes its an organ)because both are a thin layer of protection.
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.
is the organ
IT can be the castle walls
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?
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.
The cell membrane, acts as a second barriar. More protection. Keeps the stuff that pass through the cell wall. (only if its bad)
The skin
cell wall/cell membrane

it is the stomach
A semi-permeable membrane. It could be compared to dialysis tubing.

what would best represent a cell membrane in an animalcell what would best represent a cell membrane in an animalcell
An organ system is made up of cells. Cells are made up of a cell membrane, a nucleus, chloroplast, cytoplasm, tissue, and a vacuole.
