The larger a cell becomes, the more demands the cell places on what????
|
*DNA
|
|
|
What does the cell have trouble moving when it get too large?
|
*nutrients
*wastes |
|
|
Volume of a cell effects what?
|
*food
*oxygen *water |
|
|
Cell Division
|
*The process in which a cell divides into two new daughter cells.
|
|
|
When a cell divides in two, what happens to the surgace area to volume ratios in the new cells?
|
*There is no change in the amount of material exchanged.
|
|
|
When a growing cell undergoes cell division, each new cell gets?
|
*a full copy of all the DNA in the original cell.
|
|
|
What limits cell growth?
|
1. the larger a cell becomes, the more demands the cell places on the DNA.
2. The cell has trouble moving enough nutrients and wastes across the cell membrane. |
|
|
Mitosis
|
* 1st stage, division of the cell nucleus.
|
|
|
cytokinesis
|
*2nd stage, division of the cytoplasm.
|
|
|
Chromatids
|
*before cell division, each chromosome is replicated or copied.
*each chromosome consists of two identical "sister" chromatids. |
|
|
Centromeres
|
*located near the middle of the chromatids.
|
|
|
Interphase
|
* "in-between" period of a cell as one cell division after another.
|
|
|
Cell cycle
|
*a cell grows
*prepares for division *divides to form two daughter cells *begins the cell cycle again |
|
|
Events of the cell cycle
|
1. G1 phase
2. S phase 3. G2 phase |
