Homeostasisis the set of internal conditions in which an organism functions at its best. Every organism is in a constant fight to maintain homeostasis, and every single cell in the organism is a part of the battle. Every organelle in each cell is working to maintain homeostasis, including the cell membrane. The question is, how does the cell membrane aid the cell, and ultimately the overall organism. The water wants to flow from the higher concentration, which is outside of thecell, to the lower concentration, which is inside of thecell. Thecell membrane helpsto regulate and slow down the flow of water into thecell. This is yet another way that thecell membrane helps maintain homeostasis
