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 states that eukaryotic cells evolved from the symbiosis of different prokaryotic cells. Cyanobacteria are photosynthetic (can make their own food) prokaryotes. When a cell endosymbiotically takes in a cyanobacterium, the resulting cell becomes eukaryotic (as endosymbiosis leads to eukaryote formation) and gains the ability to photosynthesize (make its own food) from the cyanobacterium. Prokaryotic cells don't form from endosymbiosis of a cell and cyanobacterium in this context, and aerobic/anaerobic bacteria don't relate to this specific endosymbiosis for food - making eukaryotes.

Answer:

a eukaryotic cell that can make its own food
