The correct answer is A.
According to the endosymbiotic theory, it is stated that chloroplasts and mitochondria evolved as a result of a prokaryotic cell engulfing a bacteria cell.
Further Explanation
The endosymbiotic theory postulates that the evolution of chloroplasts and mitochondria could be traced to the prokaryotes cohabitating with other prokaryotes.
The endosymbiotic theory can be traced to former Boston University Biology, Dr Lynn Margulis who firstly proposed the theory in the 1960s, and was officially outlined in a book she published in 1981 called “Symbiosis in Cell Evolution.”
Dr Lynn Margulis proposed that the similarities between prokaryotes and organelles, alongside their appearance in the fossil record, could be described as “endosymbiosis.”
She further proposed that the best explanation for the evolution of the eukaryotic cell is “endosymbiosis.”
Dr Margulis’s hypothesis was explained as:
- Chloroplasts are the result of endocytosis of photosynthesis bacteria
- Mitochondria are the result of endocytosis of aerobic bacteria
- Anaerobic bacteria would not be able to exist in an aerobic community in both cases
- This arrangement turn out to be a mutually beneficial relationship for both cells (symbiotic)
Chloroplasts and mitochondria are two important organelles found in a cell. Organelles like chloroplasts are found in the cell of the broccoli, alongside other plants and algae. Chloroplasts are known to capture light energy and further transfer it as molecules of fuels to the plant’s tissues.
Mitochondria are majorly found in plants cells and also in human cells, and they usually convert stored energy in the molecules from broccoli into a particular cell they can use.
