  1. MITOSIS

  2. Cell Division • Cell division allows for all living things to make more cells. • Making more cells can help in body repair itself, allow an organism to grow, develop, and even reproduce.

  3. Is a process in which body (somatic) cells divide to create new ones. MITOSIS

  4. Before Mitosis… nucleus Chromosomes 2n • DNA in the nucleus condenses and forms chromosomes, which carry genetic information and begin to form cell structures. This step is called interphase. DNA

  5. Stage 1: Prophase During this stage the chromosomes make copies so that equal amounts of genetic information get transferred to the new cell, and the nuclear membrane disappears .

  6. Stage 2: Metaphase • During this stage, chromosomes line-up in the middle and prepare to split equally .

  7. Stage 3: Anaphase • At this stage, chromosomes split and move away to opposite sides of the cell.

  8. Stage 4: Telophase At this stage, the chromosomes approach the opposite ends of the cell and group together. New nuclear membranes form and two identicalcells are made. 2n 2n

  9. Asexual Reproduction • Some eukaryotic organisms, like amoebas, reproduce using MITOSIS. The parent and the offspring are identical to each other or in other words are considered clones. • Binary Fission: Happens in prokaryotes, like bacteria. The parent cell splits to make a new cell. However, there is no nucleus, thus the process happens very fast. • Budding: Some organisms, like yeast, reproduce by growing a part of their body and producing an offspring.
