Compare and contrast diffusion to osmosis.

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Osmosis is the movement of particles from an area of high concentration to an area of low concentration in a liquid through a semi-permeable membrane.

They are similar because they are both the movement of particles from an area of high concentration to an area of low concentration.

They are contrasting because osmosis includes a liquid and a semi-permeable membrane.

in addition to being able to metabolize, grow, digest food, and excrete wastes, what other functions must an organism perform if it is to survive? survival also depends on the ability to maintain one's boundaries, to move, to respond to stimuli, and to reproduce. oxygen is a survival need.
