STANDARD Botany Chloroplast structure and function MCQ Question
See the following diagram and identify X and Y with their functions
X: Grana, Function: CO₂ fixation; Y: Lamellae, Function: Photolysis of water
X: Stroma, Function: Photolysis; Y: Stroma, Function: Photolysis of water
X: Grana, Function: CO₂ fixation; Y: Stroma, Function: Photolysis of water
X: Grana, Function: Photolysis of water; Y: Stroma, Function: CO₂ fixation
Correct Answer
Detailed Explanation
In chloroplasts, grana are involved in the photolysis of water during the light-dependent reactions of photosynthesis, while the stroma is where the Calvin cycle occurs, fixing CO₂.
