diffusion types
-
diffusion
the net movement of particles, following the diffusion gradient, can either be dissolved in a fluid, or be a gas
osmosis
the net movement of water partials through a semi-permeable membrane, following the diffusion gradient
only water molecules
if theres not enough water in cells, they cripple, but if theres too much water, they burst
urea, lactic acid, carbon dioxide, glucose, and water are able to diffuse / go though osmosis into / out of cells
increased by SA, temp, and diffusion path (short)
SA yapping
as the size increases, the SA ratio decreases
