This increased the chances of horizontal gene transfer and also increase the mobility required for phagocytosis. 2.

WebMitochondria are proposed to have evolved from primitive prokaryotes that could utilize oxygen for respiration (aerobic prokaryotes) following their ingestion into the proto-eukaryotic cells through the process of phagocytosis (Fig. 20.8). The O 2 utilizing prokaryotic cells became symbionts of the proto-eukaryotic cells which had ingested them. WebIn this model, ancestral mitochondria were small heterotrophs capable of using oxygen to perform cellular respiration and thereby create useful energy. They became part of a large cell either by direct invasion as an internal parasite or as an indigestible food source.
