Exocytosis Phagocytosis Question 18 If a solute is moving down its concentration gradient and does not require a carrier protein, it moves via Simple diffusion Osmosis Facilitated diffusion Active transport Question 19 The passive process which forces fluid or solutes to move from an area of high pressure to low pressure is called Osmosis Diffusion Filtration

Part A - Concepts of Diffusion and Osmosis Drag and drop the correct terms on the left to complete the sentences about diffusion and osmosis. Diffusion and osmosis are processes. During osmosis, water moves its concentration gradient. Diffusion is the movement of solutes from an area of concentration to an area of concentration. Osmosis is the movement of a solvent from an area of concentration to an area of concentration across a selectively permeable membrane. Incorrect; One attempt remaining; Try Again; no points deducted You filled in 3 of 6 blanks incorrectly. Movement of solutes from an area of higher concentration to an area of lower concentration is a Part B - Rate of Diffusion
Matching: Match each description with the correct term. A. active transport B facilitated diffusion C. diffusion D. osmosis E. exocytosis 1. The movement of molecules from an area of HIGH concentration to an area of LOW concentration. 2. The diffusion of water molecules. 3. Energy is used to move molecules from an area of LOW concentration to an area of HIGH concentration. 4. Membrane proteins are used to move molecules across the membrane but no energy is required. 5. The movement of molecules down their concentration gradient. 6. The movement of molecules up against their concentration gradient. 7. Membrane proteins are used to move molecules across the membrane but energy from ATP is required 8. A type of active transport that involves vesicles moving molecules out of a cell.
