1. Capturing Sunlight: Plants have special green pigments called chlorophyll in their leaves. Chlorophyll absorbs sunlight, particularly the red and blue wavelengths.
2. Water and Carbon Dioxide: Plants take in water through their roots and carbon dioxide from the air through tiny openings in their leaves called stomata.
3. Chemical Reaction: Inside the plant's cells, sunlight energy is used to combine water and carbon dioxide into a simple sugar called glucose. This sugar is the plant's primary energy source. Oxygen is released as a byproduct of this reaction.
The chemical equation for photosynthesis is:
6CO2 + 6H2O + sunlight → C6H12O6 + 6O2
* CO2 = Carbon dioxide
* H2O = Water
* sunlight = Energy source
* C6H12O6 = Glucose (sugar)
* O2 = Oxygen
So, plants use photosynthesis to convert sunlight into chemical energy stored in glucose, which they use for growth, reproduction, and all their other life processes. This energy is not directly transferred to other plants, but they get their energy from consuming plants or other organisms that have consumed plants.
