In what way is meiosis different from mitosis.
|
meiosis has 2 stages of cell division rather than 1,the cell nucleus divides to produce 4 daughter cells,each with half the number of chromosomes of the parent cell.
|
|
type of cell division that results in 2 daughter cells containing identical sets of chromosomes.
|
mitosis.
|
|
The stages of mitosis
|
prophase, metaphase,anaphase and telophase.
|
|
interphase is
|
the resting stage both before and after the cell division sequence.
|
|
Stage of mitosis were the chromosomes become visible.the centrioles of the cell migrate,one to each pole of the cell, and from them spindle fibres form.The nuclear membrane breaks down.
|
Prophase.
|
|
What happens in the metaphase stage.
|
the chromosomes arrange themselves along the equator of the cell and attach to the spindle fibres, which start to pull the chromatids apart
|
|
the spindle fibres contract and pull the chromatids apart, moving them to opposite ends of the cell.
|
Anaphase
|
|
Discribe what happens in telophase.
|
The spindle fibres disintegrate and a nuclear membrane forms around the chromosomes, the cytoplasm divides forming 2 new daughter cells, each containing identical set of chromosomes.the nuclear membrane reforms, the chromosomes unravel and the cell goes into interphase again.
|
|
in mitosis the nuclear membrane reforms at
|
telophase
|
|
occurs in the germ cells of the ovary and testis
|
meiosis
|
|
occurs in the somatic cells of the body.
