Surface area does not affect diffusion
|
Detailed explanation-1: -The greater the surface area, the faster the rate of diffusion.
Detailed explanation-2: -The surface area of the membrane affects the rate of diffusion. As the surface area of the membrane increases, the rate of diffusion also increases, as there is more space for molecules to diffuse across the membrane. Distance. The shorter the distance the substances have to move, the faster the rate of diffusion.
Detailed explanation-3: -Surface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. This places an upper limitation on cell size.
Detailed explanation-4: -When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell. this is actually why cells divide.
Detailed explanation-5: -The larger the surface area to volume ratio, the quicker the rate of diffusion takes place. The substance simply has more area to diffuse across, despite being the same volume.
