F movement of salt molecules

Answer 1

Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane.

Step-by-step explanation:

Osmosis is the movement of water through a semipermeable membrane according to the water's concentration gradient across the membrane, which is inversely proportional to the solutes' concentration. While diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the solutes' diffusion in the water. The aquaporins that facilitate water movement play a large role in osmosis, most prominently in red blood cells and the membranes of kidney tubules.
