Question | Answer |
Interphase | Cell grows and makes copy of DNA |
Prophase | Chromosomes and spindle fibers form; nuclear envelope breaks down |
Metaphase | Chromosome line up across the center and detach to spindle fibers |
Anaphase | Cemtromeres split, chromatins seperate and move to opposite ends of the cell |
Telophase | Chromosomes stretch and get new nuclear envelope form around the chromosomes |
Cytokinesis | Cell pinches in two; Two new daughter cells are made and they both have the same number of identical chromosomes. |
Photosynthesis | The process by which a cell captures energy in sunlight and uses it to make food |

6 CO2 + 6 H2O -------> C6H12O6 + 6 O2 = what? | Photosynthesis |
Respiration | The process by which cells obtain energy from glucose |
Fermentation | An energy-releasing process that does not require oxygen |
Cell cycle | The regular sequence of growth and division that cells undergo |
Mitosis | The stage during which the cell's nucleus divides into two new nuclei |
Chromosomes | A doubled rod of condensed chromatin contains DNA that carries genetic information |
Cytokinesis | final stage, completes the process of cell division |
Cancer | A disease in which cells grow and divide uncontrollably, damaging the parts of the body around them |
