Types of Cell Division Prokaryotes (Bacteria & Archaeans) Eukaryotes Binary Fission. Asexual Single loop of DNA is replicated during S phase of Interphase Cell splits into 2 identical cells, each with 1 DNA molecule New cells are clones to self and to the parent Eukaryotes Mitosis Chromosome homologues are split  2 identical copies of DNA (2n) Cytokinesis divides cytoplasm  2 daughter cell clones All somatic cells Unicellular eukaryotes reproduce asexually Sponges, flatworms, seaweed, fungi, and plants Meiosis Form sex cells (gametes: ova & sperm) with ½ amount of DNA (1n) All cells transfer DNA from parent to daughter cells/ offspring
