What are the main spots in these onion root tips? |
Region of cell elongation
Region of cell division
Root cap |
|
What kind of cell is this and what does it do? |
Interphase, it is the stage of the cell cycle when a cell is preparing itself to duplicate |
|
|
What happens in G1, S, and G2 stages?? |
G1- cell growth S- DNA doubles G2-cell growth and prepares for mitosis |
|
|
What type of cell is this and what happens during it? |
Prophase, you can clearly see DNA and the nuclear membrane disappearing Chromatins come together |
|
|
What kind of cell is this in mitosis and what does it do (what happens)?? |
Metaphase, the chromosomes meet in the middle, you can see DNA lined in the middle of the cell |
|
|
What kind of cell is this in mitosis and what happens, what can you see? |
Anaphase, DNA comes apart, you can see the cromatids pulled apart to opposite sides of the cell |
|
|
What step is this in the cell cycle and what happens? What can it also be called? |
Telophase, 2 nuclei in the cell and cytokinesis happens and splits the cell |
|
|
Many of the cells of the root meristem are not undergoing mitosis, rather they are in a stage called ____________. |
Interphase |
|
|
Based upon their interpretations made above, and interphase appears to be much ________ than mitosis. |
Longer |
|
|
What processes occur in interphase cell prior to the onset of mitosis??  |
G1,S,G2 Cell grows, DNA doubles, and chromatin condenses |
|
|
Once cell division ends, the cells will exit the cell cycle and enter the interphase stage. Why is it incorrect to say that these cells are "resting"? |
Because it grows and keeps doing its job during the cycle |
