Chloroplasts are proposed to have arisen after archaea cells engulfed ___,in endosymbiosis,allowing the engulfed cell to remain,with specialized function.

Question

Quizplus · Accepted Answer

Chloroplasts are specialized organelles found in the cells of photosynthetic organisms such as plants, algae, and some bacteria. The proposed theory of endosymbiosis suggests that a photosynthetic bacterium was engulfed by a larger archaeal cell and, over time, the two organisms evolved a symbiotic relationship, with the photosynthetic bacterium becoming the modern-day chloroplasts found in photosynthetic eukaryotic cells. Therefore, the most suitable option is E - photosynthetic bacteria.
