Photosynthesis Basics

Front

What is the main purpose of photosynthesis?

Back

To convert light energy into chemical energy stored in glucose.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where do the light-dependent reactions occur?

Back

In the thylakoid membranes of the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.

Front

What is an autotroph?

Back

An organism that produces its own food through photosynthesis or chemosynthesis.

Front

What is a heterotroph?

Back

An organism that cannot produce its own food and must consume other organisms.

Front

What is the role of water in photosynthesis?

Back

Water provides electrons and protons for the light-dependent reactions and releases oxygen as a byproduct.

Front

What are carotenoids?

Back

Pigments that reflect orange and yellow light and assist in photosynthesis by capturing light energy.

Front

What is the significance of the Calvin cycle?

Back

It converts carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions.
