what is meiosis?
Cell division process that produces
gametes
with half the number of
chromosomes
as the parent cell.
how many cell divisions are involved in meiosis?
2
where does meiosis take place in humans?
ovaries
and
testes
what steps are involved in meiosis?
each pair of
chromosomes
inside the cells replicate and the cell splits in two (
mitosis
)
this forms two
identical
daughter cells. The
diploid
cell divides again
this creates
Haploid
cells (four genetically different gametes that each have
half
the number of chromosomes of the parent cell)
what happens after the cell divides in meiosis?
the male
gamete
fuses/ fertilises the female
gamete
, combining the split chromosomes
the resulting new cell divides by
mitosis
to create a
copy
of itself
mitosis
repeats many times to produce lots of cells in the
embryo
As soon as the embryo reaches a certain size, cells begin to
differentiate
(
specialise
).
what is a diploid cell?
A diploid cell is a cell that contains
two
sets of
chromosomes
, one set inherited from each parent.
what is a haploid cell?
A
haploid
cell is a cell that contains only one set of
chromosomes.
what is the difference between meiosis and mitosis?
meiosis:
2
cell divisions
4
daughter cells
haploid daughter cells (
23
)
gametes
mitosis:
1
cell division
2
daughter cells
diploid daughter cells (
23
pairs)
body cells
