INTERPHASE (G1 - S - G2)
In between divisionsCells are in this phase most of the timeCan see nucleus DNA spread out as chromatin
Can’t see chromosomes DNA gets copied (S)
Cell gets ready to divide
PROPHASE1st dividing phase
Spindle fibers form & attach to chromosomes
Nuclear membrane & nucleolus disappear
DNA scrunches into chromosomes
Centrioles appear in centrosome region & move to poles

CYTOKINESISCytoplasm splits into 2 cells
ANIMAL CELLS pinch cytoplasm in two with a ______________________CLEAVAGE FURROW
CYTOKINESISCytoplasm splits into 2 cellsPLANT CELLS can’t pinch because they have a sturdy ____________
