Meiosis
The process by which
gametes
(sperm and egg cells) are produced, with
half
the normal number of chromosomes
Normal human cells
Contain
23
pairs of
chromosomes
Gametes (sperm and egg cells)
Contain
23 single
chromosomes
Meiosis
1. Chromosomes are copied
2. Cell divides into two
3. Both cells divide one more time forming gametes
Meiosis produces four gametes from one original cell, and each gamete is genetically different
Fertilization
The joining of a male gamete (sperm) and a female gamete (egg) to form a new cell with the full number of chromosomes
Meiosis
Halves the number of chromosomes
Fertilization
Restores the full number of chromosomes
Embryo
The clump of identical cells that forms after fertilization, which then differentiates into different cell types
Mitosis
Cell division
where one cell is copied into
two identical
cells
Gametes
Cells where the chromosomes are not
paired
, e.g. sperm and egg cells
Meiosis
Cell
division
that produces non-identical
gametes
Meiosis takes place in flowering plants to produce
pollen
and
egg
cells
Sexual reproduction
Involves the fusion of male and female
gametes
, mixing
genetic
information
Sexual
reproduction
results in
variation
in the offspring
Asexual reproduction
Involves only
one
parent, no mixing of genetic information, produces genetically
identical
offspring (clones)
Asexual reproduction
does not involve
gametes
or meiosis, only mitosis
Asexual reproduction
in plants
Forming tiny
buds
that drop off and
grow
into new plants
