Question

Chloroplasts found in plants arose via ________.a. endosymbiosis of euglenids b. endosymbiosis of cyanobacteria c. endosymbiosis of proteobacteria d. endosymbiosis of dinoflagellates

Answer 1

Answer:

b. endosymbiosis of cyanobacteria

Explanation:

• A chloroplast is an organelle that plays important roles in the plants during the process of photosynthesis.
• It has certain pigments that are responsible for the trapping of the sunlight such as chlorophyll and some other pigments.
• Since each chloroplast has two membranes so named as the double-membrane organelles like mitochondria and some other organelles.
• It is considered that the evolution of the chloroplast took place by the process of endosymbiosis of cyanobacteria.
• Cyanobacteria are such kinds of prokaryotic organisms that have the ability to prepare their food by the mechanism of photosynthesis.
