Cell Division 10-2
| Question | Answer |
|---|---|
| What happens as a cell increases its size? | The cell makes more demands on DNA, but doesn't usually make more copies of it. |
| What does the rate of exchange depend on? | The rate of exchange depends on the cell's surface area. |
| As a cell grows what happens to the volume of the compared to the surface area? | The volume of the cel increases more rapidly than the surface area. |
| What is division of the cell's nucleus called? | The division of the cell's nucleus is called mitosis. |
| What is division of the cytoplasm called? | Division of the cytoplasm is called cytokinesis. |
| What happens to the cell before cell division? | The genetic information is copied so each cell can have its own complete set of information. |
| What are chromosomes made up of? | Chromosomes are made up of DNA and proteins. |
| When are chromosomes visible? | Chromosomes are visible during cell division. |
| What happen when the DNA of a cell replicates? | When the DNA replicates each chromosome represents 2 copies of DNA. |
| What are the two stages eukaryotes cell division occurs in? | The two stages are mitosis and cytokinesis. |
| What is the phase where the cells line up across the center of the cell? | This phase is metaphase. |
| What is the last stage of Mitosis called? | The last stage of Mitosis is called Telophase. |
| What do centrioles do during prophase? | They separate and take position on opposite sides of the nucleus. |
| What are the three phases of interphase? | The three stages are G1,S,and G2. |
| What happens during the phases of G1 and G2? | The cell goes through periods of intense growing activity. |
