Question

What are the various conditions necessary for photosynthesis?

Answer 1

1. Sunlight: Provides the energy in the form of photons needed to power the light-dependent reactions.
2. Chlorophyll: Acts as the green pigment that absorbs this light energy. It is located inside the chloroplasts of plant cells.
3. Carbon dioxide (CO₂): Serves as the primary carbon source for manufacturing sugars. It enters the leaves from the atmosphere through microscopic pores called stomata.
4. Water (H₂O): Supplies the essential electrons and protons (hydrogen ions) needed for the light reactions. It is absorbed from the soil by root hairs and transported to the leaves via the xylem.
