Can food pass through the cell membrane
WebCell membranes are semipermeable, meaning they have control over what molecules can or cannot pass through. Some molecules can just drift in and out, others require special structures to get in and out of a cell, while some molecules even need an energy boost … I'm just trying to show you have more water molecules than sugar molecules.
