| Term | Definition |
|---|
| smallest portion in the cell's life cycle | mitosis |
| division of the cytoplasm | cytokinesis |
| if DNA doesn't replicate the cell doesn't________ | divide |
| the in- between stage when the cell is most active | interphase |
| cluster of RNA where ribosomal RNA is made | Nucleolus |
| 2 bundles of microtubles at 90 degrees | centriole |
| in animals, the centriole is part of _______organizing system | spindal |
| DNA replicates during____________ | interphase |
| the centriole doubles during_______________ | prophase |
| what begins to form during prophase | spindal |
| what two things break down during prophase | nucleolus and nuclear membrane |
| when do chromosomes become visible | prophase |
| when is the spindal fully formed | metaphase |
| what do chromosomes do during metaphase | line up at the cells equator |
| the centromere breaks and new chromosomes are pulled apart during _______ | anaphase |
| when do new nuclei organize | telophase |
| telophase is similar to _________in reverse | prophase |
| when does cytokenesis occur (if it does) | telophase |
| during cytokenesis, what do animal cells have that plant cells do not | centriole |
| during cytokenesis, what do plant cells have that animal cells do not | cell plate |
| the gap periods where the cell is growing | G1 and G2 |
| what stage is when DNA replicates | synthesis |
| GO is the stage where cells __________ __________ | stop dividing |
| what is an example of the GO stage | nerve cells |
| what happens in meiosis that doesn't happen in mitosis | like chromosomes come together |
| in meiosis, when is the tetrad or bivalent formed | prophase I |
| in meiosis, what occurs between prophase I and telophase I | reduction division |
| in meiosis, why is there twice the number of DNA in telophase I | there will be a second division |
| in meiosis, what occurs between telophase I and telophase II | equation division |
| what are two purposes of mitosis | growth and regeneration |
| what is the purpose of meiosis | production of gametes and spores |
