What happens as a cell grows? | More demands are placed on DNA; food and oxygen are used up more quickly; the cell has more trouble moving enough materials across its cell membrane |
What happens to volume of a cell when length increases? | When length increases, the volume increases by 100 X |
The speed with which wastes are produced by a cell depends on the cell's: | Volume |
Unlike small cells, large cells have more trouble: | Moving needed materials in and waste products out |

What is cell division? | The process by which cell divides into two daughter cells |
If a normal cell divides, what can you assume about surface area? | If it divides, it has reached its full grown size |
If a normal cell divides, what can you assume about surface area? | If it divides, it has reached its full grown size |
What happens when a cell divides? | Each daughter cells receives its on copy of the parent cell's DNA. |
What would happen if a cells DNA were not copied before cell division? | It would have a DNA overload |

What is a difference between cell division in plants and animals? | Plant cells form a cell plate down the middle of the cell wall |
During normal mitotic cell division, a parent cell having four chromosomes will produce two daughter cells each containing: | 4 chromosomes |
How is the timing of the cell cycle regulated in eukaryotic cells? | Cyclin are the proteins that determine the timing of the cell cycle |
What are the phases of interphase? | G1, S, G2 |
If a cell has 5 chromosomes in g1 how many chromatids will it having during g2? | 10 |
What is the difference between chromatin and chromatids? | Chromatids are the two identical DNA strands joined by a centromere; Chromatin is the material that makes up chromosomes |
