Movement in and out of cells
- Diffusion
- Factors affecting diffusion
- Distance the molecule has to travel
- Thin cell membrane
- The concentration gradient
- Low concentration inside the cytoplasm
- Large surface area
- Diffusion is faster in warmer temperatures
- The net movement of molecules from a region of high concentration to a
region of low concentration. Down a concentration gradient
- Through a partially permeable membrane
- Passive
- Osmosis
- Plant
- Animal
- Active Transport
