Question

According to the endosymbiotic theory,the original chloroplast was a
A)chemisynthetic archaea.
B)green algae.
C)purple sulphur bacteria.
D)mitochondria.
E)photosynthetic prokaryote.

Accepted Answer

The endosymbiotic theory suggests that the original chloroplast was a photosynthetic prokaryote that was engulfed by a larger host cell and eventually evolved into a symbiotic relationship, leading to the development of modern-day chloroplasts in eukaryotic cells. The other options listed, such as chemisynthetic archaea or purple sulfur bacteria, do not have the necessary characteristics to form the chloroplasts found in eukaryotic cells.
