osmosis is diffusion through a membrane
Osmosis is a type of diffusion but through a barrier (membrane) while "diffusion" is not specified if there is a physical barrier or not. Gases diffuse through each other readily.
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules from high to low through a partially-permeable membrane. This is what makes osmosis different to diffusion.
Diffusion is when materials move from areas of high concentration (high amount) to areas of low concentration (low population).Osmosis is the same as diffusion, but it's only when WATER moves from areas of high concentration to areas of low concentration. STAY IN SCHOOL JUNIORS!!(and pee-wees too. . .)
it doesn't. you may have asked the question wrong!however, osmosis is slightly like diffusion, it involves water molecules.Osmosis consists of water moving from a high WATERconcentration; to a low WATER concentration.extra information:diffusion, is just the process of a substance moving from a high concentration to a low concentration. are you mental?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
weener!
Active transport can occur against a diffusion gradient ("uphill flow).

osmosis is diffusion through a membrane
Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water. Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane). Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.

Active transport requires energy while passive transport does not.
I'm not going to tell you the answer, stop coming here for answers, use a textbook or something...DONT CHEAT
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules from high to low through a partially-permeable membrane. This is what makes osmosis different to diffusion.
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
