Generally, with higher light and temperature intensity, the rate of photosynthesis increases. Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Temperature and Light Intensity In fact, the larger part of the world’s population gets over 80% of its food directly from plants. Easy to understand photosynthesis lesson. This whole process takes place in several stages. And there are six factors that influence the rate of photosynthesis: Namely, the higher the light intensity, temperature, carbon dioxide and chlorophyll concentration, the faster the rate at which photosynthesis occurs. They are for reverse respiration – allow carbon dioxide in and let oxygen out. Photosynthesis uses carbon dioxide, water, and light energy to make sugar. And animals are part of the food chain, which normally starts with plants. The first step in photosynthesis is (a) convert light energy into chemical energy (b) reduction of C0 2 gas to carbohydrates (c) photolysis of water (d) absorption of light energy by chlorophyll. Following is the fundamental equation of photosynthesis 6CO 2 + 6H 2 O (+ light energy) → C 6 H 12 O 6 + 6O 2. Produces oxygen that sustains all the life.
