1 D 3 A 2 E 5 B 4 C INTERPHASE PROPHASE METAPHASE ANAPHASE TELOPHASE
Interphase Prepares for cell division Divided into 3 phases G1 phase Cell increases in size S phase DNA is replicated G2 phase Cell continues to grow G2 of INTERPHASE Centrosomes (with centriole pairs) Chromatin Nuclear envelope
Prophase Chromosomes condense Centrioles move to opposite sides of cell Spindle fibers form from centrioles Nuclear envelope breaks down PROPHASE Fragments of nuclear envelope Kinetochore centrioles Spindle microtubules
Metaphase Chromosomes line up in the middle of the cell along the metaphase plate Spindles are fully attached to each sister chromatid METAPHASE Metaphase plate Spindle
Anaphase Sister chromatids separate to opposite ends of the cell Each sister chromatid is now considered to be a daughter chromosome What about the other spindle? ANAPHASE Daughter chromosomes
Telophase Nuclear envelope reforms around 2 new nuclei Chromosomes begin to uncoil TELOPHASE Nucleolus forming Nuclear envelope forming
What Comes Next?
Cytokinesis: division to create 2 independent cells Cytokinesis differs in animal and plant cells. In animal cells, the membrane pinches closed. In plant cells, a cell plate forms
Plant vs. Animal Cells Plant cytokinesis Animal cytokinesis
What stage of mitosis is Ms. Sernik pointing at?
