Cells with a larger surface area-to-volume ratio, such as small cells like bacteria or single-celled organisms, will typically have a faster rate of diffusion across the surface. This is because a larger surface area allows for more space for molecules to diffuse in and out of the cell more efficiently.
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
Proteins play a key role in aiding diffusion across cell membranes by acting as channels or carriers. Cell recognition is facilitated by cell surface markers such as glycoproteins and glycolipids, which help cells identify and communicate with each other.
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
Microvilli, which are tiny finger-like projections on the surface of the cell membrane. These structures increase the surface area available for diffusion and absorption of molecules in simple columnar epithelial cells.
The primary driving force of facilitated diffusion are surface cell proteins. These proteins transport substances in and out of the cell.

Move things across the cell membrane.
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.

The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
