In C4 plants, Calvin cycle works at:
In C4 plants, Calvin cycle works at:
Show Hint
C4 plants:
Mesophyll cells: initial CO\(_2\) fixation.
Bundle sheath cells: Calvin cycle.
Calvin cycle occurs in the stroma.
Mesophyll cells: initial CO\(_2\) fixation.
Bundle sheath cells: Calvin cycle.
Calvin cycle occurs in the stroma.

- Stroma of bundle sheath chloroplasts
- Grana of bundle sheath chloroplasts
- Grana of mesophyll chloroplasts
- Stroma of mesophyll chloroplasts
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
C4 plants have a specialized mechanism to concentrate CO\(_2\) around RuBisCO.
They have two types of cells: mesophyll cells and bundle sheath cells.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the C4 pathway.
Step 3: Detailed Explanation:
In C4 plants, the Calvin cycle occurs in the bundle sheath cells.
The initial fixation of CO\(_2\) occurs in mesophyll cells.
The Calvin cycle takes place in the stroma of bundle sheath chloroplasts.
The grana are thylakoid stacks where light reactions occur.
Thus, the Calvin cycle works at the stroma of bundle sheath chloroplasts.
Step 4: Final Answer:
Calvin cycle works at the stroma of bundle sheath chloroplasts in C4 plants.
Hence, the correct option is (A).
