What does osmosis mean?

Answer 1

It means the diffusion of fluids through a membrane. Oxygen is diffused into your blood through the alveoli walls by osmosis. The difference between diffusion generally and osmosis is the permeable membrane.osmosis is a type of diffusion. diffusion is when particles spread out from an area of high concentration to evenly disperse themselves in a container that they're in.

for example: if you go to a concert or something they usually use fog machines. when they first turn it on, the fog is only in a small area. if you notice 5 minutes later, the fog will be spread out in the air of the entire building.

osmosis is the same thing except more specific: it is the movement of WATER molecules across a CELL's MEMBRANE. (water moving from an area with lots of water to an area with less water)

Answer 2

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration, in order to equalize the concentrations on both sides of the membrane. It is a passive process that does not require energy.

Answer 3

Osmosis is the movement of water from where it is in high concentration across a membrane to where it is in low concentration.
