| Question | Answer |
|---|---|
| Diffusion | the movement of particles from an area of higher consentration to an area of lower consentration |
| Osmosis | the diffusion of water across a cell membrane |
| Passive transport | simple diffusion through a cell membrane's protiens |
| Active transport | moving materials through the cell membrane's protiens from an area of lower consentration to an area of higher consentration |
| Endocytosis | the cell membrane surrounds a large particle bringing it into the cell |
| Exocyctosis | The ER or gogi complex forms a vescile that takes large particles for removal from the cell |
| Photosynthesis | producing glucose by capturing light energy (takes place in the chloroplasts) |
| formula of photosynthesis | 6co2+6h2o+light/ energy=c6h12o6+6o2 |
| cellular respiration | producing ATP by using oxygen to break down sugar |
| fermentation | producing ATP from sugar without using oxygen |
| the cell cycle | the life cycle of a cell |
| Binary fission | simple cell division in bacteria in which one cell splits into two |
| mitosis | the division of a cell's nuculus into two so that each daughter cell recieves an identical copy of the cell's original chromosomes |
| formula for cellular respiration | c6h12o6+6o2=6co2+6h2o+ATP |
| chromosome | a coiled structure of DNA and protein that forms in the nuculus during cell division |
| cytokinesis | after mitosis the process in which the cytoplasm divides into two |
