Question

The site of photosynthesis in cyanobacteria is ________.

• A. Chloroplast
• B. Chromatophores
• C. Thylakoids
• D. Chlorosomes

Hint:

Thylakoids in cyanobacteria serve as the site for the light-dependent reactions of photosynthesis.

Answer 1

The Correct Option is C

Step 1: Understanding the question.
The question asks about the site of photosynthesis in cyanobacteria. Cyanobacteria are photosynthetic bacteria, also known as blue-green algae.
Step 2: Analyzing the options.
- (A) Incorrect, chloroplasts are found in plant cells, not in cyanobacteria.
- (B) Incorrect, chromatophores are membrane-bound structures in certain bacteria, but not the site of photosynthesis in cyanobacteria.
- (C) Correct, cyanobacteria have thylakoids, which are the membrane-bound structures where photosynthesis takes place.
- (D) Incorrect, chlorosomes are found in green sulfur bacteria, not in cyanobacteria.
Step 3: Conclusion.
Thus, the correct answer is (C) Thylakoids.
