Question | Answer |
diffusion of water through a semipermeable membrane where water moves from high to low | Osmosis |
3 types of solutions a cell can be placed in | Hypertonic ; Hypotonic ; Isotonic |
the solute concentrate (particle concentrate) is greater on the outside than it is on the outside | Hypertonic Solution |
the solute concentrate is less on the outside of cell than on the inside | Hypotonic Solution |
the solution concentrate is the same on the inside and outside of cell | Isotonic |
2 ways a cell gets materials in and out of cell | Passive Transport ; Active Transport |
movement of materials across a cell membrane w/o the use of energy | Passive Transport |
2 examples of passive transport | Diffusion ; Osmosis |
movement of materials across a cell membrane that requires to use energy | Active Transport |
2 types of active transport | Endocytosis;Exocytosis; |
An AT process by which particles leave the cell | Exocytosis |
AT procees in which cell surrounds particle in vesicle to bring it in | Endocytosis |
2 types of endocytosis | Pinosytosis; Phagosytosis |
movement of particles form high to low concentration | diffuison |
process by which plants capture energy from the sun and convert it into food | photosynthesis |
pigmit in chlorplast that absorbs sunlight | Chlorophyll |
formula for photosythisis | CO2 + H2O to sun C6H12O6 + O2 gluctose |
2 ways animals get energy | Cellular Respiration , Fermentation |
uses oxygen to break down food (way animal get energy) | Cellular Respiration |
takes place in absence of oxygen | fermantation |
Chemical that requires oxygen | Aerobic Rxn. |
chemical that doesnt require oxygen | anaerobic rxn. |
the life cycle of a cell . | The Cell Cycle |
phase between cell division; spends most of time; | Interphase |
4 phaseses of mitosis | prophase; metaphase; anaphase; telophase |
chromatin condenses; nucleaus , nuclear membrane dissapears; centrioles to opp. poles; spindle fibers form b/w centrioles | prophase |
chromosomes line up at equator of cell | metaphase |
centromeres split; chromotids move to opp poles and are called chromosomes | anaphase |
chromosomes uncoil; nuclear mem. and nucleaus reappear; spindles leave | telophase |
