Passive transport processes like diffusion and facilitated diffusion move materials across the cell membrane without requiring energy. Diffusion occurs when molecules move from areas of high concentration to low concentration, while facilitated diffusion involves the help of protein channels to facilitate the movement of specific molecules.
Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
The process is called passive diffusion, where molecules move from an area of higher concentration to an area of lower concentration across the cell membrane.
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
One method of movement across the membrane is by diffusion, which is related to osmosis.
Active Transport
Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.

Osmosis.
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
