| respiration | process by which cells obtain energy from glucose |
| fermentation | energy-releasing process that does not require oxygen |
| selectively permeable | some substances can pass through the membrane while others cannot |
| diffusion | main method by which small molecules move across the cell membrane from a high concentration to an area of low concentration |
| osmosis | the diffusion of water molecules though a selectively permeable membrane |
| passive transport | movement of dissolved materials through a cell membrane without using cellular energy |
| active transport | movement of materials through a cell membrane using cellular energy |
| photosynthesis | process by which a cell captures energy in sunlight and uses it to make food |
| pigments | colored chemical compounds that absorb light |
| chlorophyll | main photosynthetic pigments in chloroplasts |
| photosynthesis equation | 6CO2 + 6H2O ---- C6H12O6 + 6O2 |
| chloroplasts | green organelles inside plant cells |
