| A | B |
|---|
| interphase | the longest part of the cell cycle when the cell is dividing |
| mitosis | the part of the cell cycle during which the nucleus divides |
| prophase | phase of mitosis when chromosomes coil up and become visible |
| metaphase | phase of mitosis when the chromosomes line up down the middle of the cells |
| anaphase | phase of mitosis when the centromere divides and the chromatidsd each become 2 separate chromosomes |
| telophase | phase of mitosis when the spindle fibers start to disappear, new nuclear membranes form, and the chromosomes start to uncoil. |
| cytokinesis | division of the cell's cytoplasm after mitosis |
| cell cycle | the normal sequence of development and division of a cell |
| asexual reproduction | type of reproduction in which there is only 1 parent; offspring is identical to the parent |
| budding | when a bud develops on the side of a parent organism, and grows until it forms a complete/almost complete organism that is identical to parent (hydra, potatoes, etc.) |
| regeneration | growth of new tissue at the site of a wound or lost limb (worms, starfish, sponges, etc.) |
| sexual reproduction | type of reproduction when there are 2 parents; new offspring has genetic info from both parents. |
| reasons why cells need to divide | growth, development, and repair |
| how single-celled eukaryotic cells divide | mitosis and cytokinesis |
| binary fission | when the cell splits into 2 identical daughter cells; how prokaryotic organisms (bacteria) divide |
| prokaryotic cells | cells that have NO nucleus |
| eukaryotic cells | cells that have a nucleus |
| 3 activities during interphase | cell grows and carries out normal functions, DNA is copied, and cell prepares for mitosis |
