Mitosis and Meiosis

Mitosis produces..

Identiical body cells to repair and replace

Mitosis maintains..

the same amount of chromosomes in daughter cells as parent cells

Mitosis goes through PMAT..

once

In mitosis, unicellular organisms

reproduce asexually

Does crossing over occur in Mitosis?

No

Mitosis can happen

repeatdly throughout an organisms life

Mitosis -Interphase

DNA gets copied and chromosomes duplicate

Mitosis - Prophase

Chromosomes condense

Mitosis - Metaphase

Chromosomes line up single file in the middle of the cell

Mitosis - Anapahse

Spindles pull apart chromatids to opposite ends of the cell

Mitosis - Telophase

Chromatids are on opposite ends of the cell, and nuclei is forming

Cytokinesis

Splits the cytoplasm into 2 new cells

End result of PMAT in Mitosis

2 identical diploid cells with 46 chromosomes

Both do cell …

divison

Both duplicate

chromosomes before splitting in interphase

Both are involved in making ..

new cells

Both perform

PMAT

Both do cyto-

-kinesis at the end of PMAT

Both copy..

cells DNA during Interphase

Both help organisms..

grow and reproduce

Start with

a single diploid cell

Both start in

the nuceli of animal and plant cells

Both use chromosmes..

to carry genetic information

Both use spindles..

to seperated and move chromosomes during cell division

Both are types of

cell division

Meiosis performs PMAT

twice

Meiosis - Crossing over occurs

with homologous pairs in prophase 1

In meiosis the cells have

genetic variation due to crossing over genetic material

Meiosis makes

Gametes (egg and sperm cells)

Meiosis does reduction division

46 chromosmes to 23

Meiosis - Interphase

DNA copies and chromsomes duplicate

Meiosis - Prophase 1

Crossing over occurs with homologous pairs of chromosomes to swap genetic material

Meiosis - Metaphase 1

Pairs line up in the middle of the cell

Meiosis - Anaphase 1

Pairs get seperated by the spindles and move to opposite ends of the cells

Meiosis - Telophase

Chromosomes are on opposite ends of the cell’s, and the nuclei is forming

End of Meiosis 1

2 non-identical daughter haploid cells with 23 chromosomes

Meiosis - Prophase 2

Chromosomes are condensing

Meiosis - Metaphase 2

Chromosomes line up single file in the middle of the cells

Meiosis - Anaphase

Chromatids get pulled apart by the spindles to opposite ends of the cells

Meiosis - Telophase

Chromatids are opposite ends of the cells, and nuclei is forming

End of Meiosis 2

4 non-identical haploid cells with 23 chromosomes
