PROKARYOTES:
BINARY FISSION (SPLITTING IN HALF!)
MITOSIS:
Cell division process which produces
two daughter cells
NO CHANGE IN GENETIC CONTENT:
parent cells and daughter cells
are both diploid
Organisms use mitosis for
GROWTH AND REPAIR
INTERPHASE: Cells have two copies of each
chromosome (here, one pair of little chromosomes,
and one pair of big chromosomes).

Division of the
cytoplasm into
