Answer:
How have prokaryotic cells produced aerobic eukaryotic
cells and photosynthetic aerobic eukaryotic cells?
- Based on Endosymbiotic theory Eukaryotic cells evolved from
prokaryotic cells (endosymbiotic bacteria). Endosymbiotic events
gave rise to mitochondria and chloroplasts.
- This theory was developed extensively by Lynn Margulis
(American biologist)
- According to this theory, eukaryotic cells initially didn't
contain mitochondria and chloroplasts and began as anaerobic
organisms. Eukaryotic cells subsequently established endosymbiotic
relationship with bacteria and utilized their oxidative
phosphorylation system.
- First endosymbiotic event led to the ancestral eukaryotic cell
consume aerobic bacteria that evolved into mitochondria and second
endosymbiotic event led to the ancestral eukaryotic cells consume
photosynthetic bacteria that evolved into chloroplasts.
