Answer 1

1. Diffusion is the movement of solutes from an area of higher concentration to an area of lower concentration in solution.

2. Osmosis is the diffusion of water across a selectively permeable membrane such as plasma membrane

3. Pinocytosis means cell drinking (pinching) and is distinguished from phagocytosis in that smaller vesicles are formed and they contain molecules dissolved in liquid rather than particles

4. If a cell is placed into a solution that neither shrinks nor swells, the solution is called Isotonic
