Cell Reproduction
| Question | Answer |
|---|---|
| DNA | a chemical that contains information for an organism's growth and functions |
| chromosomes | DNA wrapped around protiens |
| Interphase | The part of the cell cylce during wich a cell is not dividing, growth and develop |
| Mitosis | thee part of the cell cycle during wich the nucleus divides. |
| Cell cycle | The normal sequence of development and division of a cell |
| Cytokinesis | The division of a the parent cell's cytoplasm |
| Asexual reproduction | One organism produces the new organism or organisms that are identical to itself and that live independantly of it. |
| Binary fission | the form of asexual reproduction occurring in prokaroytes |
| regeneration | The process of new tissue growth at three sites |
| chromatids | a small organelle that divides ekaryotic cells |
| cetromere | Compacted DNA |
| binary fission | the form of asexual reproduction ocurring in prokayotes |
| sexual reproduction | when two organisms produce another organism,unique organism |
| prophase | the step of mitosis when the DNA in the nuecleuses of a cell condenses and becomes visible under a light microscope |
| metaphase | the step of mitosis when the chromosomes line up in the middle of the cell |
| anaphase | the step of mitosis when the chromosomes split, resulting in two seperate identical chromosomes and then are pulled to topposite sides of the cell |
| telophase | the step of mitosis when a new nuceur membrane forms around each group of choromsomes. The chromosomes then return to their threadlike form. |
| budding | a process in which an organism develops buds o its body |
| spindle fibers | strings atttached to the chromosomes to pull them apart |
