Goal: Understand How Cells Divide by MitosisNew Words: chromosome, chromatin, centromere, chromatid, centrosome
Do Now: List 3 things you have learned about the Cell Cycle
1. Label chromosome, chromatin, and DNA on the picture.2. Label centromere and chromatid on the chromosomes.

A. Chromosomes line up in the middle of the nucleus
B. Chromatids move to opposite end of the cell
C. Nuclear membrane dissolves
D. Cell splits with its own set of chromosomes
E. Cell grows and DNA replicates
Do Now:
1. Interphase
2. Prophase
3. Metaphase
4. Anaphase
5. Telophase
• Spindle fibers pull chromatids apart to opposite end of the cell
• DNA is replicated
• Nuclear membrane dissolves
• Increasing cell size and grow
• Production of many organelles and molecules
• Chromosomes line up in the middle of the cell• Spindle fibers attach to each chromosome at the centromere
• Wind DNA ( chromatin) into chromosomes
• Nuclear membrane forms• DNA unwinds into chromatin
Interphase
Prophase
Metaphase
Anaphase
Telophase
• Centrioles and spindle fibers become visible
• Centrioles and spindle fibers become non visible
Goal: Understand How Cells Divide by MitosisNew Words: mitosis, prophase, metaphase, anaphase, telophase
Cytokinesis • Cell splits with its own set of chromosomes
Mitosis
Number of cell division?
Exchange of genetic material between chromosomes?
Number of functioning cell produced from the original?
Number of chromosomes of daughter cells compare to parent cells
How is the genetic material of final cells produced?
Function of cells produced?
One
No
Two daughter cells
Equal number
In human is 46 chromosomes
Identical as the original
• Growth or replacement of body cells
• Same as the parent cells
