Front

Why are plants usually green?

Back

Because the chlorophyll reflects green light

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to convert carbon dioxide and water into glucose and oxygen.

Front

What is the overall equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis produces oxygen and organic compounds that are essential for the survival of most life forms.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).
