Biology: Mitosis
cell division questions
| Question | Answer |
|---|---|
| What is Mitosis? | Mitosis is the process of cells dividing in order to make new cells, Mitosis is also known as cell division |
| What are chromatids? | Chromatids are two halves of a chromosome that are identical |
| What are Centrioles? | Centiroles are pasta looking cyliander organelles that also have spindle fibres attached to them |
| Where is the Centromere on a chromosome? | The Centromere is located directly in the middle of each chromosome |
| What is the Interphase and why is it nesscary? | The interphase is the phase before mitosis where the chromatin is duplicated and its nesscary because each new cell must have 46 chromatin |
| What is the cell cycle? | The cell cycle is the period from one cell division to the next cell division |
| What is the order of each cell cycle phase? | Prophase,Metaphase,Anaphase,Telophase |
| What does unicellular mean? | Unicellular means one celled |
| What happens during the prophase? | The centrioles move to the poles of the cell and the spindle fibres start to form and grow longer |
| What happens during the Metaphase? | The spindle fibres move the chromosomes to the equator of the cell and postion them until they are lined up. |
| What happens during the Anaphase? | In the anaphase the chromosomes are pulled apart and start to move to the poles of the cell, the cell then starts to strecth longer |
| What happens during the Telophase? | During the Telophase the cell walls pinch in which is also know as cytokinesis , the nuculear membran begins to reform and the cells are then sperated |
| What are Spindle fibres? | Spindle fibres are attached to the centrioles and are bassically strings of protein |
| Which part of the cell is the equator? | its the middle. |
| What is happens during cytokinesis? | during cytokinesis cells will pinch in. |
