2. 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
