NEET Biology Photosynthesis In Higher Plants Based Practice Questions & Answers with Viewers Discussion and Detailed Explanation

Answer: (b)

During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Factors which influence the rate of photosynthesis are of two kinds - external (environmental) or internal. The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants. Plants factors affecting photosynthesis includes number, age, size and orientation of leaves, mesophyll cells and chloroplast, internal $CO_{2}$ concentration and the amount of chlorophyll.
