Hello. This question is incomplete. The full question is:
"What is the correct description of the relationship between osmosis and diffusion? a.diffusion is a type of osmosis that occurs across a cell membrane. b.osmosis is a type of diffusion that occurs across a cell membrane. c.osmosis is a type of diffusion that requires energy on the part of the cell, whereas diffusion happens freely. d.osmosis is not directly related to diffusion. osmosis involves the movement of liquids. diffusion involves movement of gases."
Answer:
a. diffusion is a type of osmosis that occurs across a cell membrane.
Explanation:
Osmosis is the movement of the solvent (water) through a semipermeable membrane from the least concentrated medium to the most concentrated medium, in order to equalize the concentrations on both sides. Diffusion, in turn, is a physical process in which substances (solute) are transported from a more concentrated region to a less concentrated one (in favor of the concentration gradient) in a random and spontaneous manner. In this case, we can say that diffusion is a type of osmosis, however, it transports different things through the membrane. In osmosis, the transport is of liquid things, in the diffusion the transport is of solid things.
