is a process by which phototrophs convert light energy into chemical energy.
The word “photosynthesis” is derived from the Greek words "phos" (which means “
”) and "σύνθ-εóîς" (which means “
.”) And so it means “combining together with the help of light.”
The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.
Following is the photosynthesis formula:
6 CO2 + 6 H2O —> C6 H12 O6 (
) + 6 O2 (
).
