Biology: Exchanging Materials

HideShow resource information

Exchanging Materials.

Osmosis and Diffusion is when water and dissolved substances move along a concentration gradient. From a higher concentration to a lower concentration gradient.

Active Transport is when these things are absorbed against a concentration gradient using energy from Respiration.
Plants absorb ions from dilute solutions by active transport.

Active transport takes place in the opposite direction to normal…
