The theory of endosymbiosis suggests that chloroplasts and mitochondria were once free-living prokaryotes, that
were engulfed by larger prokaryotic cells. Eventually, this relationship lead to the development of eukaryotic cells
with cellular organelles. These organelles included mitochondria, and in some cases, chloroplasts.
Why would engulfing these smaller prokaryotic cells be an advantage to the larger prokaryotic cells?
A)
The smaller prokaryotic cell would be protected by the larger cell.
B)
The smaller prokaryotic cell produced the proteins needed by the larger
cell
)
The smaller prokaryotic cells would provide a source of energy to the
larger cells.
D)
The smaller prokaryotic cell provided genetic information so the larger cell
could evolve.
