How did eukaryotic cells likely evolve
WebMitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis. Mitochondria and chloroplasts likely began as bacteria that were engulfed by larger cells (the ... Web29 de set. de 1995 · Eukaryotic cells evolved from bacterial ancestors whose fused genome was replicated from a single origin and whose means of segregating sister chromatids depended on fixing their identity at replication.
