Which process is directly facilitated by chlorophyll in plants?

• A. Transpiration
• B. Nitrogen fixation
• C. Photosynthesis
• D. Cellular respiration

Answer: (C)

Chlorophyll is the green pigment found in the chloroplasts of plant cells and is crucial for the process of photosynthesis. During photosynthesis, chlorophyll absorbs light energy, primarily from the sun, and converts it into chemical energy. This process uses carbon dioxide and water to produce glucose and oxygen. The energy captured by chlorophyll enables the conversion of solar energy into chemical energy, which is vital for the plant's growth and sustenance. Transpiration involves the movement of water vapor from within the plant to the atmosphere and is not directly facilitated by chlorophyll. Nitrogen fixation is the process by which certain bacteria convert nitrogen gas from the atmosphere into a form usable by plants. While important for plant nutrition, it does not involve chlorophyll. Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water; although it occurs in all living cells, including those of plants, chlorophyll does not play a direct role in this process. Thus, the role of chlorophyll is explicitly tied to photosynthesis, making it the correct answer.
