Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated diffusion follows the same rules as regular diffusion (higher to lower concentration and no energy input), but uses protein carrier molecules to allow substances that are fat soluble to diffuse through the cell membrane.
facilitated diffusion the solutes are moved from an area of high concentration to an area of lower concentration and with Active transport, the solutes are moved from low concentration to an area of high concentration.
Diffusion moves materials from an area of high concentration to an area of low concentration and does not require energy. Active transport uses energy to move materials from high to low concentration.
Facilitated diffusion occurs in order to maintain homeostasis within a cell. If there is more of something, such as water, inside a cell than outside the cell, diffusion allows the water to flow out of the cell so that an equal amount of water molecules exists both inside and outside the membrane. This requires little or no energy from the cell itself.
Active transport is when the cell takes in or excretes material through the membrane so that the amount of material inside and outside the membrane is different. This requires energy from the cell to occur.
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Facilitated diffusion:Does not require energyIs still passive transport (like normal diffusion)Is still diffusion down a concentration gradient.Requires the assistance of membrane proteins.Active Transport:Requires energy (ATP).Is NOT passive transport.Substance is translocated across the membrane AGAINST a gradient.Requires use of energy-induced carrier transport proteins.Comparison:Both require transport proteins.One requires energy where the other doesn't.One is active, one is passive.One moves down a concentration gradient where the other moves against.
The most essential difference is that one is active (uses energy) and one is passive (doesn't require energy). Take note whenever you see the word 'active' in this context- it denotes that energy is required for it to occur, usually against the concentration gradient. Facilitated diffusion is just another passive process by which molecules move from an area of high concentration to low concentration. Note that this requires no energy to occur, except it differs from diffusion in that a carrier molecule is required (usually because the molecule is too large to freely cross the plasma membrane)
Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
both need transport protein
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
i don't know i need help pleas?
Passive diffusion is what naturally happens without any assistance of any sort. Facilitated diffusion requires extra energy from extra sources to happen.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.

Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
