cell transport
cousins middle school, 7th grade, cell transport
| Term | Definition |
|---|---|
| active transport | the movement of substances across a cell membrane that uses ENERGY- can move LARGE particles (such as in endocytosis and exocytosis) OR move against equilibrium |
| passive transport | this movement of a substance across a cell membrane that uses NO ENERGY- moves small particles- moves things from areas of high concentration to areas of less concentration until equilibrium is acheived |
| endocytosis | a process in which a cell surrounds a particle and brings it in using energy- creates a vesicle around it |
| exocytosis | a process in which a cell surrounds a particle and pushes it out using energy- creates a vesicle around it |
| diffusion | movement of particles across a membrane from high concentration to lower concentration until equal= any substance other than water |
| osmosis | same as diffusion but only with water |
| photosynthesis | process by which plants (and some algae and bacteria) make glucose from the sun- happens in chloroplasts |
| cellular respiration | process by which cells break down sugar for energy happens in the mitochondria, uses oxygen- water is a waste product |
| fermentation | process by which the cell breaks down sugar for energy, happens in the cytoplasm, does not use oxygen- lactic acid and alcohol can be waste products |
| homeostasis | the maintenance of a constant internal state in a changing environment- a cell's happy place |
| semipermeable membrane | a barrier that lets some things go through, but not everything |
| glucose | sugar |
