Vocabulary: cell cycle, interphase, mitosis, cytokinesis

Review:

1. interphase and cell division

2. two complete sets of DNA, twice the size of when it was first formed

3. They are identical.

4. Chromosomes form (prophase), chromosomes line up (metaphase), chromosomes separate (anaphase), nuclei form (telophase).

5. In both plant and animal cells, cytokinesis is the division of the cytoplasm. In plant cells a cell plate forms and becomes a new cell wall and cell membrane. In animal cells, the cell membrane pulls inward and pinches into two new cells.

6. Yes, because cytokinesis is the division of the cytoplasm, and prokaryotes have cytoplasm to divide.
