the cell membrane allows what substance to enter the cells.
Cell membranes are porous and will allow water into the cell (in a regulated manner, of course).
Cell membranes allow nutrients into cells and waste products pass out of cells. Cell membranes provide a protective barrier for cells — they don't let everything in, especially large particles. Cell membranes are important in the communication between cells. Cell membranes are reservoirs for fatty acids.

cell membranes
they allow some substances to come in and out of the cell. this is because they are semipermeable.

Yes all cells have cell membranes
The Cell Membrane
It can allow nutrients to enter a cell without compromising the integrity of the cell. Semipermeable membranes abound in nature.
Which of these have very thin cell membranes?
