What is the chemical equation for photosynthesis?
What is the chemical equation for photosynthesis?
- $C6H12O6 + 6O2 + light + chlorophyll \rightarrow 6CO2 + 6H2O$
- $6CO2 + 6O2 + light + chlorophyll \rightarrow C6H12O6 + 6H2O$
- $6CO2 + 6H2O + light + chlorophyll \rightarrow C6H12O6 + 6O2$ (correct)
- $6CO2 + C6H12O6 + light + chlorophyll \rightarrow 6H2O + 6O2$
What is the role of chlorophyll in photosynthesis?
What is the role of chlorophyll in photosynthesis?
- Releasing oxygen as a byproduct
- Activating the water molecules for the reaction
- Breaking down glucose into carbon dioxide and water
- Absorbing photons of light and converting light energy into chemical energy (correct)
How is the presence of starch detected as a product of photosynthesis?
How is the presence of starch detected as a product of photosynthesis?
- By boiling in alcohol, which changes the color of starch
- By adding iodine, which turns the starch blue (correct)
- By exposing to sunlight, which causes starch to appear
- By mixing with water, which reveals the starch content
