Which of the following is an input of photosynthesis?

• A. Glucose
• B. Oxygen
• C. Carbon dioxide
• D. Chlorophyll

Answer: (C)

In photosynthesis, carbon dioxide is a key input that plants use to produce glucose and oxygen. During the process, plants absorb carbon dioxide from the atmosphere through small openings in their leaves called stomata. This carbon dioxide then enters the chloroplasts, where it combines with water in the presence of sunlight to synthesize glucose, which serves as an energy source for the plant. At the same time, oxygen is released as a byproduct into the atmosphere, which is essential for the respiration of almost all living organisms. The roles of glucose and oxygen are actually the products rather than inputs in photosynthesis, and while chlorophyll is crucial in capturing light energy, it is not classified as an input because it is a pigment that aids in the process rather than a substance that is consumed or transformed during the reaction. Thus, carbon dioxide is rightly recognized as a vital input in the photosynthesis process.
