Answer:
C. Diffusion and osmosis work together to create equilibrium in the cell.
Step-by-step explanation:
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. It occurs passively, without the input of energy. In the context of a cell, diffusion allows molecules to move freely across the cell membrane until the concentration of the molecules is equal on both sides.
Osmosis, on the other hand, is a special type of diffusion that specifically involves the movement of water molecules across a selectively permeable membrane. It occurs in response to a concentration gradient of solutes (such as ions or molecules) between two solutions. Water moves from an area of lower solute concentration (hypotonic) to an area of higher solute concentration (hypertonic) in order to equalize the concentration on both sides of the membrane.
Together, diffusion and osmosis play a crucial role in maintaining equilibrium or homeostasis in the cell. They ensure that the concentration of solutes and water is balanced both inside and outside the cell, allowing the cell to function properly.
