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

A. A eukaryotic cell that can make its own food

Explanation;

-The endosymbiotic theory describes how a large host cell and ingested bacteria could easily become dependent on one another for survival, resulting in a permanent relationship.

-Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory. An endosymbiont is one organism that lives inside of another one.

-The mitochondrion and the chloroplast are both organelles that were once free-living cells. They were prokaryotes that ended up inside of other cells (host cells). They may have joined the other cell by being eaten (a process called phagocytosis), or perhaps they were parasites of that host cell.
