What is the primary role of chlorophyll in photosynthesis?
What is the primary role of chlorophyll in photosynthesis?
Chlorophyll absorbs light energy from blue and red wavelengths to initiate photosynthesis.
What are the main differences between chlorophyll a and chlorophyll b?
What are the main differences between chlorophyll a and chlorophyll b?
Chlorophyll a is the primary pigment directly involved in photosynthesis, while chlorophyll b serves as an accessory pigment that broadens the absorption spectrum.
Write the overall equation for photosynthesis and identify its reactants.
Write the overall equation for photosynthesis and identify its reactants.
The overall equation is $6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂$, with carbon dioxide and water as the reactants.

Study Notes
Chlorophyll Function
- Definition: Chlorophyll is a green pigment found in plants, algae, and cyanobacteria.
- Location: Primarily located in chloroplasts of plant cells.
-
Main Roles:
- Absorbs light energy, mainly from the blue and red wavelengths.
- Reflects green light, which is why plants appear green.
-
Process:
- Captures light energy to initiate photosynthesis.
- Converts light energy into chemical energy during the light-dependent reactions.
-
Types:
- Chlorophyll a: Primary pigment involved in photosynthesis.
- Chlorophyll b: Accessory pigment that broadens the absorption spectrum.
Photosynthesis Equation
-
Overall Reaction:
- 6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
-
Components:
-
Reactants:
- Carbon dioxide (CO₂): Absorbed from the atmosphere through stomata.
- Water (H₂O): Taken up from the soil by plant roots.
-
Products:
- Glucose (C₆H₁₂O₆): A simple sugar used for energy and growth.
- Oxygen (O₂): Released as a byproduct into the atmosphere.
-
Reactants:
-
Stages of Photosynthesis:
- Light-dependent reactions: Convert light energy into ATP and NADPH.
- Light-independent reactions (Calvin cycle): Use ATP and NADPH to synthesize glucose from CO₂.
Chlorophyll Function
- Green pigment found in plants, algae, and cyanobacteria, primarily located in chloroplasts of plant cells
- Absorbs light energy, mainly from blue and red wavelengths, reflecting green light, hence the green appearance of plants
- Captures light energy to initiate photosynthesis, converting it into chemical energy during the light-dependent reactions
- Two main types: chlorophyll a (primary pigment involved in photosynthesis) and chlorophyll b (accessory pigment broadening the absorption spectrum)
Photosynthesis Equation
- 6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
- Reactants: carbon dioxide (CO₂) absorbed from the atmosphere through stomata & water (H₂O) taken up from the soil by plant roots
- Products: glucose (C₆H₁₂O₆) used for energy and growth & oxygen (O₂) released as a byproduct into the atmosphere
- Two stages: light-dependent reactions converting light energy into ATP and NADPH, and light-independent reactions (Calvin cycle) using ATP and NADPH to synthesize glucose from CO₂
