2. Cellular reproduction (in eukaryotes)
Asexual reproduction of unicellular organisms.
Growth, tissue repair, and replacement of damaged cells in multicellular organisms.
Involves two processes:
Mitosis: division of the nucleus, so that DNA is parceled out equally to two daughter cells.
Cytokinesis: division of the cytoplasm to form two independent cells.

3. During interphase, the nucleus is filled with diffuse chromatin
During interphase, the nucleus is filled with diffuse chromatin. Loosely packed DNA is necessary for genes to be active.

4. During mitosis, the chromosomes become visible
During mitosis, the chromosomes become visible. Tightly packed DNA is easier to “deal out” equally when cells divide.

9. Four replicated chromosomes in prophase
Two cells, each with four single chromosomes, in telophase
