The Greek words phs (pronounced “fos”) and v (pronounced “synthesis”) are where the word “photosynthesis” originates.Phs stands for “light” and for “combining together.” This signifies “combining with the aid of light.”

In addition to green plants, other creatures can also engage in photosynthesis. Several prokaryotes are among them, including cyanobacteria, purple bacteria, and green sulfur bacteria. The photosynthesis of these organisms is comparable to that of green plants.The numerous biological processes are then powered by the glucose created during photosynthesis. Oxygen is a by-product of this physio-chemical process.
