- 1Cell divisionReproduction at the cellular lever
- 2Purpose 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 - 3Asexual reproductionProduces offspring identical to original cell or organism - inheritance of all genes from one parent
- 4Sexual reproductionProduces off that are similar to the parents - inheritance of unique sets of genes from two parents
- 5ProkaryotesBacteria and Archaea
- 6Binary fission"dividing in half"
- 7Stages of Prokaryote Binary Fission1. 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 - 8Eukaryotic- more complex
-more genes
- most genes are stored on multiple chromosomes within nucleus - 9Chromatin- long DNA molecule
- proteins that help maintain the chromosome structure and control gene activity - 10Division Preparation- chromatin becomes compact
- 11Eukaryotic cell division- duplicates all of it's chromosomes
- two copies are sister chromatids
-joined by
