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 forGROWTH AND REPAIR

INTERPHASE: Cells have two copies of each chromosome (here, one pair of little chromosomes, and one pair of big chromosomes).WATCH CAREFULLY!

Cytokinesis Division of the cytoplasm into two cells.

THIS IS NOT A STAGE, BUT AN EVENT THAT MARKS THE END OF TELOPHASE
