Where in a plant cell does the Calvin Cycle take place?

• A. Thylakoid membrane
• B. Nucleus
• C. Cytoplasm
• D. Stroma of the chloroplast

Answer: (D)

Verified step by step guidance

1. Understand that the Calvin Cycle is a part of photosynthesis, which occurs in plant cells.
2. Recall that photosynthesis takes place in the chloroplasts of plant cells.
3. Differentiate between the two main stages of photosynthesis: the light-dependent reactions and the Calvin Cycle (light-independent reactions).
4. Identify that the light-dependent reactions occur in the thylakoid membranes, while the Calvin Cycle occurs in a different part of the chloroplast.
5. Recognize that the Calvin Cycle takes place in the stroma of the chloroplast, which is the fluid-filled space surrounding the thylakoids.
