Question

based on the endosymbiotic theory, what cell would result from the endosymbiosis of a cell with a cyanobacterium?
a eukaryotic cell that can make its own food
a prokaryotic cell that can make its own food
an aerobic bacterium
an anaerobic bacterium

Explanation:

The endosymbiotic theory posits that eukaryotic cells evolved from prokaryotic - prokaryotic symbiotic relationships. Cyanobacteria are photosynthetic prokaryotes. When a cell undergoes endosymbiosis with a cyanobacterium, the resulting cell is a eukaryotic cell that can perform photosynthesis (make its own food) due to the presence of the cyanobacterial symbiont which becomes a chloroplast in the eukaryotic cell over time.

Answer:

a eukaryotic cell that can make its own food
