| Question | Answer |
| Cell division | Reproduction at the cellular lever |
| Purpose of cell division | - reproduction of single celled organisms - growth of multicellular organisms from a fertilized egg into an adult - repair and replacement of cells - sperm and egg production |
| Asexual reproduction | Produces offspring identical to original cell or organism - inheritance of all genes from one parent |
| Sexual reproduction | Produces off that are similar to the parents - inheritance of unique sets of genes from two parents |
| Prokaryotes | Bacteria and Archaea |
| Binary fission | "dividing in half" |
| Stages of Prokaryote Binary Fission | 1. duplication of the chromosomes and separation of the copies 2. continued elongation of the cell and movement of the copies 3. division into two daughter cells |
| Eukaryotic | - more complex -more genes - most genes are stored on multiple chromosomes within nucleus |
| Chromatin | - long DNA molecule - proteins that help maintain the chromosome structure and control gene activity |
| Division Preparation | - chromatin becomes compact |
| Eukaryotic cell division | - duplicates all of it's chromosomes - two copies are sister chromatids -joined by |
