5. Individual cells and/or whole organisms go through what cellular process?
8. What process do cells grow, replace, and repair?
10. This phase has 3 stages (S and G phases) and is the preparatory phase before mitosis occurs. Microtubules organize copied organelles and DNA for division.
12. What is a full set of chromosomes called?
14. Offspring produced by a single parent is…?
15. Also known as the “first gap” and “second gap” phases, these phases occur before mitosis occurs and this is when the cell grows bigger and copies/makes proteins and organelles for mitosis.

1. What phase does the chromosomes condense?
3. In ___________ the chromosomes line up in the middle.
4. In plants, a cell plate forms down the middle of the cell, while in animal cells a cleavage furrow forms during this phase
6. In this phase the cell is nearly done dividing, and the nuclear membranes begin to form.
7. _______________ are specialized chromosome regions that connect sister chromatids
9. These are identical copies of DNA that remain together until they are split during mitosis:
11. What is a half set of chromosomes called?
