    Biology Revision questions 2
    1. Explain how apicomplexans seem to have evolved through various stages of endosymbiosis.

    1.1. Apicomplexans from endosymbiosis (Bodyl et. al 2013)
    1.1.1. Started with an anaerobic bacteria without a cell wall and another anaerobic bacterium as an endosymbiont
    1.1.2. The nucleus evolved autogenously after endosymbiosis
    1.1.3. The proto-Eukaryotic cell then acquired a cilium and cytoskeleton from a spirochete
    1.1.4. The acquired bacteria underwent transformation into true organelles
    1.1.5. Endosymbiotuc gene replacement took place
    1.1.6. Import of proteins with N-terminal into the endosymbiont
    1.1.7. Formation of eukaryotic cells (Apicomplexans)

    2. What are the similarities and differences between a moss sporophyte and a fern ...
