Name the three important functions of mitosis and cytokinesis
|
1) Growth 2) Maintenance 3) Repair
|
|
What are the four phases of mitosis?
|
1) Prophase 2) Metaphase 3) Anaphase 4) Telophase
|
|
A list of key events in ________ of Mitosis:
-nucleus contents visible -chromatin---> Chromosomes -Centrioles separate and move to opposite poles -nuclear envelope disappears -nucleus becomes invisible. What phase of mitosis is this? |
Prophase
|
|
-Chromosomes move to the center of the cell
-centromeres on the equator -spindle fibres attach to the centromere What phase of mitosis is this? |
Metaphase
|
|
-Chromatids separate at the centromeres
-Chromatids move to opposite poles of the cells -Same number of single copy chromasomes should be at each pole What phase of mitosis is this? |
Anaphase
|
|
-Chromosomes at opposite ends of the cell
-decondense to form chromatin -nuclear envelope reappears What phase of mitosis is this? |
Telophase
|
|
mitosis is a process of nuclear division and it is followed by ________
|
Cytokinesis
|
|
What process has the following steps?
-cytoplasm division -cell membrane pinches in to form two distinct cells -ends with separation of two identical daughter cells. The daughter cells are now in G1 of interphase |
Cytokinesis
|
|
How do Cytokinesis and Mitosis differ in a plant and animal cell?
|
Plants do not have centrioles but they form a spindle apparatus
-Rigid cell wall of a plant is much stronger than membrane of animal cell -Cell wall does not pinch during cytokinesis (in plant) -Instead, membrane called cell plate forms between the two daughter cells creating a new cell wall. |
