| photosynthesis | the process in which plants use energy from the sun and make their own food |
| respiration | the process of making energy for the cells |
| chloroplasts | location of photosynthesis |
| mitochondria | location of respiration |
| diffusion | movement of materials from area of high concentration to low |
| osmosis | movement of water molecules from high to low concentration |
| passive transport | requires no energy |
| active transport | requires energy |
| hypotonic | particles outside a cell are low and inside are high |
| hypertonic | particles outside a cell are high and inside are low |
| isotonic | same amount of particles inside and outside of the cell |
| cell membrane | organelle that allows movement of materials into and out of a cell |
| selectively permeable | allows some materials to go into the cell but not others |
