| Question | Answer |
|---|---|
| What are the two interphase? | growth phase and synthesis phase |
| What is growth phase? | the cell is growing and developing its organelles |
| What is the synthesis phase? | the chromosomes replicated in the nucleus |
| What is mitosis? | the life cycle of a cell |
| What happens in prophase? | Centrioles move to opposite poles |
| what happens in metaphase? | spindle fibers attached on the chromosomes and line up in the middle (centromere) |
| what happens in anaphase? | spindle fibers retract and pull 1/2 the chromosomes towards each centriole |
| what happens in telophase? | spindle fibers are back in the centrioles and nuclear envelopes start to form back around both sets of chromosomes |
| What is a cell check point? | 3 parts on the cell cycle where proteins determine whether the cell should divide or not |
| What is cytokinesis? | the cell membrane pinches off in the middle and separates into 2 daughter cells |
| What is apoptosis? | cell dies when it is too old function |
