CELL DIVISION OBJECTIVES: Describe the main events of the cell cycle.
Mitosis: Mitosis is a type of cell division in which a daughter cell receives the same number of identical chromosomes as the parent cell. Mitosis is necessary.

Cell Division pg. 67 Cell life cycle - changes a cell goes through from when formed to division 1.Interphase - cell grows, metabolic activities 2.Cell Division - cell reproduces Cell life cycle - changes a cell goes through from when formed to division 1.Interphase - cell grows, metabolic activities 2.Cell Division - cell reproduces

Cell Division DNA replicates before Mitosis Mitosis division of the nucleus Forms two daughter nuclei Cytokinesis - division of cytoplasm, begins when mitosis is almost completed DNA replicates before Mitosis Mitosis division of the nucleus Forms two daughter nuclei Cytokinesis - division of cytoplasm, begins when mitosis is almost completed

Cell Division Prophase 1.chromatin coil and shorten to chromosomes, 2 chromatids, held together by centromere 2.Centrioles separate and move to opposite sides 3.Mitotic spindle forms, scaffolding 4.End - nuclear membrane and nuclei broken down, attach to spindle fibers Prophase 1.chromatin coil and shorten to chromosomes, 2 chromatids, held together by centromere 2.Centrioles separate and move to opposite sides 3.Mitotic spindle forms, scaffolding 4.End - nuclear membrane and nuclei broken down, attach to spindle fibers

Cell Division Metaphase 1.Sister chromatids align midway between centrioles Metaphase 1.Sister chromatids align midway between centrioles

Cell Division Anaphase 1.Centromeres split 2.Chromatids move slowly apart, become chromosomes 3.Finished when chromosomes have stopped Anaphase 1.Centromeres split 2.Chromatids move slowly apart, become chromosomes 3.Finished when chromosomes have stopped

Cell Division Telophase 1.Reverse prophase 2.Chromosomes uncoil, become chromatin 3.Spindle breaks down 4.Nuclear membrane forms around mass of chromatin 5.Nuclei appear in each daughter nuclei Telophase 1.Reverse prophase 2.Chromosomes uncoil, become chromatin 3.Spindle breaks down 4.Nuclear membrane forms around mass of chromatin 5.Nuclei appear in each daughter nuclei

Cell Division Cytokinesis 1.Division of cytoplasm 2.Late anaphase- telophase 3.Cleavage furrow - midline of spindle, pinches cytoplasmic mass into two parts Cytokinesis 1.Division of cytoplasm 2.Late anaphase- telophase 3.Cleavage furrow - midline of spindle, pinches cytoplasmic mass into two parts
