Question:
Cellular organelle associated with photosynthesis is
Cellular organelle associated with photosynthesis is
Show Hint
Chloroplasts have their own DNA (ctDNA), similar to mitochondria, suggesting they were once independent prokaryotic cells!

The Correct Option is A
Solution and Explanation
Concept:
Photosynthesis is the process by which light energy is converted into chemical energy (glucose).
• This process occurs in specialized double-membrane organelles in plant cells and algae.
• These organelles contain the green pigment called chlorophyll.
Step 1: Identifying the Photosynthetic Organelle.
Chloroplasts are the dedicated sites for both the light-dependent and light-independent reactions. The thylakoid membranes within the chloroplast capture sunlight using chlorophyll pigments.
Step 2: Distinguishing from other Organelles.
Ribosomes are associated with protein synthesis. Mitochondria are associated with cellular respiration and ATP production. The ETR (Electron Transport Chain) is a process occurring within membranes, but the organelle as a whole is the Chloroplast. Final Answer: The cellular organelle directly associated with photosynthesis is the Chloroplast.
