1. ONION ROOT TIP CELLS DIVIDING THE PHASES OF THE CELL CYCLE Ed Bassett, Olympia High School THE PHASES OF THE CELL CYCLE Ed Bassett, Olympia High School

2. Cells on the left show nucleoi (present only during interphase)

3. Prophase - left center; metaphase - center

4. Prophase (left); Metaphase w/spindle (upper right)

5. Prometaphase/late prophase (left center). Note absence of nuclear envelope

6. Metaphase w/ spindle apparent (left center)

7. Early anaphase (left center) with telophase/cytokinesis just below

8. Anaphase (left center)

9. Telophase (left center)

10. Late telophase/cytokinesis; Note cell plate

11. Onion Root tip cells dividing Cell division in Eukaryotes (plants, animals, etcetera) varies slightly. Plant cell cytokinesis involves the formation of a CELL PLATE. In animal cells, cytokinesis involves the formation of a CLEAVEAGE FURROW. Cell division in Eukaryotes (plants, animals, etcetera) varies slightly.
