Which of the following is NOT a factor influencing photosynthesis?

Soil type does not directly influence the process of photosynthesis. Photosynthesis primarily occurs in the leaves of plants, where chlorophyll captures sunlight and converts carbon dioxide and water into glucose and oxygen. The main factors that affect the rate of photosynthesis include temperature, light intensity, and the availability of carbon dioxide.

Temperature affects enzyme activity involved in photosynthesis; certain temperatures can optimize or hinder this process. Light intensity influences the amount of energy available for photosynthesis, generally leading to higher rates at increased light levels, up to a saturation point. The availability of carbon dioxide is also crucial, as it is one of the key reactants needed for the photosynthetic process.

In contrast, soil type impacts plant growth by determining nutrient availability and water retention but does not affect the photosynthetic mechanism directly.
