show the chromosomes arranged by size
7. 2 sets of chromosomes
8. 1 set of chromosomes

Cell Cycle
• 1. a repeating sequence of cellular growth
and division during the life of an organism
• 2. G1, S, G2, mitosis, cytokinesis
• 3. interphase
• 4. to make sure the cells are healthy and
properly developed (the right size and the
correct genetic material)
• 5. uncontrolled cell division

To make an exact copy of the nucleus for:
– A. Asexual reproduction
– B. Growth
– C. Repair/healing
Asexual Reproduction
• 1. Reproduction involving 1 parent.
Offspring have identical DNA.
• 2. budding, regeneration, sporulation,
vegetative propagation,
• Binary fission- in bacteria (They are
prokaryotes and do not have a nucleus, so
they do not do mitosis.)
