vocab
Cell division that produces genetically identical daughter cells
Mitosis
What does it do
growth and repair
Does it create genetic variety
yes
2 identical daughter cells form. The cell membrane finishes dividing
Telophase
Chromosomes line up in the center of the cell. Spindle fibers attach to each chromosome
Metaphase
Cell division that produces genetically different daughter cells
Meiosis
Does it create genetic variety
No
how many times does the cell divide
2
Sister Chromatids are pulled apart
Anaphase 2
The cell splits into two haploid cells (each with half the chromosomes)
Telophase 1
Division of the cytoplasm and formation of 2 new cells
Cytokinesis
How many cells are made
2
How many cells are made?
4
Chromosomes condense and become visible. Nuclear membrane begins to break down
Prophase
Chromosomes line up single file in the middle
Metaphase 2
Organelle that makes spindle fibers used in cell divison
Centrioles
How many times does the cell divide
1
Where does it happen?
gametes (sperm and egg)
Chromosomes pairs line up in the middle of the cell
Metaphase 1
Whole chromosome pairs are pulled apart to opposite side
Anaphase 1
Long strand of condensed DNA that holds genetic info
Chromosome
example of Mitosis
skin cell growth
Example of Meiosis
sperm or egg cells
Chromosomes get ready for division again
Prophase 2
Chromosomes condense and swap DNA making each gamete genetically unique
Prophase 1
