Question

in the above diagram, water moves in to or out of the cells by this process
active transport
exocytosis
pinocytosis
osmosis

Explanation:

Osmosis is the process where water moves across a semi - permeable membrane (like the cell membrane) from an area of lower solute concentration to an area of higher solute concentration. Active transport requires energy (usually ATP) to move substances against their concentration gradient. Exocytosis is the process of vesicles fusing with the plasma membrane to release their contents outside the cell. Pinocytosis is a form of endocytosis where the cell takes in extracellular fluid. In the given diagram, water movement (not other substances) across the cell membrane is shown, which is characteristic of osmosis.

Answer:

Osmosis
