ONION ROOT TIP CELLS
DIVIDING
THE PHASES OF THE CELL CYCLE
Ed Bassett, Olympia High School
Cells on the left show nucleoi (present only
during interphase)
Prophase - left center; metaphase - center
Prophase (left); Metaphase w/spindle (upper right)
Prometaphase/late prophase (left center). Note
absence of nuclear envelope
Metaphase w/ spindle apparent (left center)
Early anaphase (left center) with
telophase/cytokinesis just below
Anaphase (left center)
Telophase (left center)
Late telophase/cytokinesis; Note cell plate
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.
