What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

What role do stomata play in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases; they enable carbon dioxide to enter the leaf and oxygen to be released.

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the respiration of most living organisms.

How does light intensity affect the rate of photosynthesis?

Back

In general, as light intensity increases, the rate of photosynthesis increases, up to a certain point, after which it may plateau.

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it is split into oxygen and hydrogen, providing electrons and protons for the process.

What is the overall chemical equation for photosynthesis?

Back

The overall chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
