Photosynthesis is the method through which green plants and some other organisms convert light energy into chemical energy. In green plants, light energy is absorbed during photosynthesis and utilized to transform water, carbon dioxide, and minerals into oxygen and organic compounds rich in energy.

It would be unthinkable to undervalue the significance of photosynthesis in sustaining life on Earth. If photosynthesis stopped, there would quickly be minimal food or other organic materials on Earth. The majority of organisms would vanish, and eventually Earth's atmosphere would be almost lacking in gaseous oxygen. The only organisms that could survive in such conditions would be chemosynthetic bacteria, which can harness the chemical energy from specific inorganic compounds and are therefore independent of light energy conversion.

Utilize this useful lesson plan to instruct your students on the process of photosynthesis. Numerous activities are included, intended to take approximately 90 minutes. Photocopiable worksheets for students and their answers are also included at the end.
