describe the difference between sexual and asexual reproduction
sexual reproduction
-sex, can identify if male or female.
-produce cells called gametes. sperm: male & egg: female (plants- sperm is known as pollen grain, egg is known as pollen grain)
-meiosis- the type of cell that produces gametes. effect- half the total adult number of chromosomes in the gamete cell. (in humans the total number of chromosomes is 46 per cell, however in gametes the total number is 23 per gamete cell) the process of reducing 46 from 23 is called (cell division) meiosis.
-process of fertilisation. gamete cells (sperm cells from male) and egg cells from female fuses together.
-variation- board. many differences in individuals of the sexual reproduction population.
assexual reproduction
-no sex, can not be determined if male or female.
-does not produce gametes
-no meiosis only mitosis in eukatyotic cells/ binary fission in prokaryotic bacterial cells, in this process the number of cells (chromosomes) are maintained constantly. eg. if there is 20 cells will divide to produce 2 cells each with 20 chromosomes, they are identical.
-no gametes, no cell fusion so no fertilisation
-small amount of variation due to mutation, but they are mostly identical= clone.
question- what is the difference between mitosis and meiosis?
