opposite poles |
|
|
sperm |

|
|
egg |
female sex cell |
|
|
offspring |
a new combination of unique DNA |
|
|
diploid cell |
body cell |
|
|
haploid |
sex cell |
|
|
fertilization |
sperm enters egg and fertalizes it |
|
|
interphase 1 |
cell gets ready to split, nuclear membrane dissapeares, spindle fibers show |
|
|
interphase 2 |
cell gets ready to split a second time, nuclear membrane still not there, spindle fibers still here |
|
|
prophase 1 |
cell starts to split, spindle fibers coming, chromosomes scattered |
|
|
prophase 2 |
cell starts to split a second time, chromosomes still scattered |
|
|
metaphase 1 |
chromosomes line up in the middle of the cell, spindle fibers attach to chromosomes. |
|
|
metaphase 2 |
chromosomes in middle of cell again, spindle fibers attach to chromosomes again. |
|
|
anaphase 1 |
chromosomes split away to opposite sides of the cell |
|
|
anaphase 2 |
chromosomes split away again and got to each of there "poles" |
|
|
telophase 1 |
cell almost done splitting, chromosomes find another pair |
|
|
telophase 2 |
Cell almost done splitting again. chromosomes find a pairyc |
|
|
cytokenesis 1 |
cytoplasm splits to make 2 cells, nuclear membrane appears spindle fibers fade away |
|
|
cytokenesis 2 |
cytoplasm splits to make 4 cells, nuclear membrane appears spindle fibers fade |
