In the facilitated diffusion the transport protein is needed as well in the active transport.
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!
Osmosis is an example of passive transport, specifically a type of facilitated diffusion. In osmosis, water molecules move across a semipermeable membrane from an area of high concentration to an area of low concentration without the use of energy.
Diffusion - spreading of molecules in solid, liquid and gas Osmosis - diffusion of water; affected by tonicity Facilitated diffusion - transports of substances are facilitated by carrier proteins
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.
osmosis is the movement of water across the plasma or cell membrane

The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
PASSIVE TRANSPORTS ARE OF TWO TYPES. 1)SIMPLE DIFFUSION 2)FACILITATED DIFFUSION 1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops. 2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.
Mediated Transport has an extra step of binding to a carrier protein, while Passive transport does not bind to a protein. Both of them however, move along the concentration gradient (High--> Low)
