Cell Division Flashcards
where/when is meiosis used
its used in sexual reproduction
what does meiosis result in
it results in the formation of 4 non-identical daughter cells
what does mitosis result in
mitosis results in the formation of 2 genetically identical daughter cells
when is mitosis used
1) Asexual reproduction
2) Cell reparations
3) Growth
what do cells in reproductive organs divide by
they divide by meiosis
how many sets of chromosomes does each cell have
2 sets of chromosomes
what type of cells are gamete cells
they are diploid cells
what are haploid cells
haploid cells are cells that have only one copy of each chromosome
how many chromosomes do haploid cells in the human cell have
they have 23 cells
how does the random pairing of the male and female gamete create variation
the random pairing of the male and female gamete create variation as all gametes are genetically different
what happens when both sex cells combine
they start to divide by mitosis - the cells reproduce asexually -
when do the cells start to differentiate
the cells start to differentiate when the embryo reaches a certain size
