Step 1
Movement of molecules from a higher concentration to a lower concentration: This is the basic definition of diffusion, where molecules move from an area of high concentration to an area of low concentration. So, the answer for this is $\boxed{\text{diffusion}}$. Show more…

Classify each of the examples below as simple diffusion, facilitated diffusion, or osmosis. Provide an explanation to support your classification. If there are more solutes inside the cell than outside of the cell, water will move into the cell. A sugar molecule moves through the cell membrane through a protein. Carbon dioxide moves out of the cell from a higher concentration to a lower concentration without help.

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.
