|
what happens in interphase |
1) DNA is replicated 2) cell grows |
|
|
what happens in prophase |
1) chromatids are held together by the centromere 2) The spindle extends between the two ends of the cell |
|
|
what happens in metaphase |
1)chromatids father in the central region 2) spindle fibers attaches to the centromere of each chromatids |
|
|
what happens in Anaphase |
spindle fibers divides the centimetres to opposite poles of the cell |
|
|
what happens in telophase |
the nuclear membrane reforms around each group of chromosomes |
|
|
what happens in cytokinesis |
division of cytoplasm and plant cells grow a cell plate and cell divides into two |
|
|
why is it important to have checkpoints |
To check for any mistakes |
|
|
state the 3 checkpoints and what happens in them |
1) G1 checkpoint: if the DNA is found to be damaged or incomplete the cell stops and enters G0 2) G2 checkpoint: The replicated DNA is checked for completeness and lack of damage and advances into mitosis stage 3) M checkpoint: occurs at metaphase insures that spindle fibres are attached correctly |
|
|
stages of binary fission |
1) DNA replication and cell elongate 2) division into two |
|
|
mitosis definition overview and where it occurs |
mitosis is the way our cell produces two daughter cells by entering the stages interphase mitosis and cytokinesis and it occurs inside the cell |
|
|
the difference between binary fission and mitosis |
binary fission occurs in prokaryotic cells and mitosis occurs in eukaryotic cells |
|
|
explain mitosis in plant cells |
in vascular plants only cells in meristematic tissues can complete mitosis and divide |
|
|
what is the role of cell division |
To divide cells for growth, damaged cells or when a cell is dying |
|
|
what is a haploid |
having 2 different sets of unpaired chromosomes |
|
|
what is a diploid |
having the same set of chromosomes |
