Correct Answer: Carbon dioxide ko organic molecules mein convert karna.
Step 1: Understand that the Calvin cycle is a process that occurs in plants.
Step 2: Know that it takes place in the chloroplasts, which are the parts of plant cells that help with photosynthesis.
Step 3: Recognize that the main ingredient the Calvin cycle uses is carbon dioxide (CO2) from the air.
Step 4: Learn that the cycle transforms carbon dioxide into organic molecules, which are compounds that contain carbon and are essential for life.
Step 5: Conclude that the primary purpose of the Calvin cycle is to convert carbon dioxide into these organic molecules, which plants use for energy and growth.
