What is the difference between osmosis and diffusion (include examples of each) and how does a cell membrane control these 2 processes?

Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. ... Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.

Passive osmosis and diffusion

Passive osmosis and diffusionBecause the membrane acts as a barrier for certain molecules and ions, they can occur in different concentrations on the two sides of the membrane. Such a concentration gradient across a semipermeable membrane sets up an osmotic flow for the water.

Explanation:

have a great day!

a historian researching the immigration policies of the early 1900s would expect a source written today,rather than in 1910 to :

( a ) be more interested in objective data and statistics.
