Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules move down their concentration gradient across the cell membrane.
Facilitated transport is not common in bacteria because they typically rely on simple diffusion or active transport mechanisms to move molecules across their cell membranes. Bacteria have evolved to efficiently transport nutrients and other molecules through these methods, making facilitated transport less necessary for their survival and growth.
Charged particles move across membranes through the process of facilitated diffusion or active transport. Facilitated diffusion involves the movement of particles through protein channels, while active transport requires energy to move particles against their concentration gradient.
In the facilitated diffusion the transport protein is needed as well in the active transport.
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.*This is from Wikipedia.....
The two types of diffusion are passive diffusion and facilitated diffusion. Passive diffusion is the movement of molecules across a membrane without the need for a protein carrier, driven by the concentration gradient. Facilitated diffusion involves the use of specific protein channels or carriers to help molecules move across the membrane, still following the concentration gradient without requiring energy.
Facilitated diffusion moves molecules through cell membranes passively.
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.

Through facilitated diffusion
Particles move through cell membranes w/out the use of energy by cells.

Passive diffusion - Urea has its own concentration gradient so it will go from an area of high concentration through the cell membrane into an area of lower concentration.
Facilitated diffusion helps molecules move across cell membranes by utilizing specific carrier proteins. It does not require energy input, as molecules move down their concentration gradient. This process is crucial for transporting larger molecules like glucose and ions across cell membranes.
In the facilitated diffusion the transport protein is needed as well in the active transport.
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane
Because facilitated diffusion moves moolecules from regions of higher concentration toward lower concentration, active transport moves particles through membranes from region of lower concentration to a region of higher concentration
