Question

multiple choice question
what type of prokaryote might have formed endosymbiotic relationships with other larger bacteria, eventually evolving into a chloroplast?
a hypothetical archeon
an anaerobc bacterium
a photosynthetic bacterium
a non - photosynthetic pigmented bacterium

Explanation:

Chloroplasts are organelles responsible for photosynthesis. According to the endosymbiotic theory, they originated from prokaryotes that could perform photosynthesis. Photosynthetic bacteria, like cyanobacteria, are thought to have formed endosymbiotic relationships with larger cells and evolved into chloroplasts over time.

Answer:

A photosynthetic bacterium
