Solutions8
intracellular - ANSWERS-fluid found inside the cells
extracelluar - ANSWERS-fluid found outside the cells
osmosis - ANSWERS-fluid moving passively across semipermeable membrane from areas with
more fluid to areas with less fluid
diffusion - ANSWERS-solutes move through semipermeable membrane from area of higher
concentration to an area of lower concentration
