starch doesnt diffuse through the dialysis membrane.
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.
i think its Matrix
allow substances to diffuse through it.
capillaries are the site of exchange of materials where the needed substances in the tissue diffuse into them from the capillary through diffusion.while the metabolic wa ste from tissues diffuse into the capillary and taken away.the capillaries have a big surface area and their cells is one cell thick to enable diffusion to take place fast.
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
soluble materials which can diffuse passively .
magnets
There are a huge number of ways that this can occur. Water can simply diffuse through the cell membrane through osmosis, while other substances diffuse through special channels in the cell membrane. Some substances have to be brought into the cell through active transport, which requires the use of ATP.
The semi-permeable membrane in cells. Allows some substances to go through and not others.
