All cells need to expel waste. Red blood cells are known for taking in oxygen and distributing it throughout the body. That only happens because red blood cells have hemoglobin inside, which oxygen binds to, and the hemoglobin releases it at appropriate times.
The cell's membrane separates the inside from the outside and allows certain chemicals to pass, others are kept out.
permiable
The cell membrane who ever is looking this up the cell membrane is what let things go in and out of the cell it is also known as the traffic cop:) if need any more answers look up the answer by typing in the search bar up above Thank you :)
Cell membranes are selectively permeable, meaning only certain materials can enter the cell. This selective permeability allows cells to regulate the movement of substances in and out of the cell to maintain internal balance and proper functioning. Substances such as water, ions, and small molecules can pass through the membrane via various transport mechanisms like diffusion, osmosis, and facilitated diffusion.
A cell membrane surrounds all cells and controls the movement of substances.
