Based on the endosymbiotic theory, what cell would result from the endosymbiosis of a cell with a cyanobacterium?

The following options are attached to the question given above:

A) A eukaryotic cell that can make its own food

B) A prokaryotic cell that can make its own food

C) An aerobic bacterium

D) An anaerobic bacterium

ANSWER

The correct option is A.

Endosymbiotic theory is a theory that talks about the evolution of eukaryotic cells from prokaryotic organisms. The theory proposes that mitochondria and plastids {chloroplast}, which are found in eukaryotic cells were once prokaryotic cells. Based on this theory, an endosymbiosis of a cell with a cynaobacterium would result in a eukaryotic cell that can manufacture its own food because it contains plastids.
