14 terms
Terms | Definitions |
|---|---|
Passive transport | cell uses no energy. |
Diffusion | high to low. movement of molecules until equilibrium is reached. |
Osmosis | diffusion of water through a membrane. |
Facilitated diffusion | carrier proteins help large molecules cross the plasma membrane. |
Active transport | cell uses energy. |
Pinocytosis | process by which certain cells can engulf and incorporate droplets of fluid. |
Exocytosis | membrane of a vacuole fuses, "bloops", w/ the cell membrane spitting out its membrane. |
Endocytosis | process of taking matter into a cel by infolding of the cell membrane. |
Phagocytosis | pseudopods (extensions of the cytoplasm) surround & engulf large fod particles forming food vacuoles. |
Hypertonic environment | concentration greater inside cell. water flows out of the cell. |
Isotonic environment | solute & free water concentrations are same inside & out. water flows in & out of cell @ = rate. |
Hypotonic environment | concentration greater outside cell. retains H2O. |
Kinetic Theory of Matter | -everything needs energy to move. -The warmer the temp., the faster the movement. |
De-Naturing | the altering of a cell, so that it isn't able to perform it's function. |
