| A | B |
| diffusion | form of passive transport/materials move from higher to lower concentration |
| intracellular circulation | movement of materials within a cell |
| intercellular circulation | movement of materials from one cell to another |
| cyclosis | circulating of cytoplasm within a cell |
| hemoglobin | substance that allows blood to carry oxygen |
| active transport | process using energy to move particles through a cell membrane |
| closed circulatory system | system that uses veins to carry the blood |
| tracheophytes | complex plants that use vascular tissue |
| hydra | has 2 cell layers, no transport system, absorbs things w/diffusion |
| bryophytes | simple plant, uses no vascular tissue (like moss) |
| amoeba | organism using active transport/diffusion to absorb materials (i.e. water) |
| phagocytosis | form of active transport/cell surrounds/flows around undissolved particles |
| pinocytosis (PINCH!) | form of active transport/cellular energy used to to take in dissolved particles |
