Photosynthesis

Front

What is photosynthesis?

Back

The process in which plants make their food using sunlight, carbon dioxide, and water.

Front

What is the main purpose of the light reactions in photosynthesis?

Back

To provide the energy and electrons for the Calvin cycle.

Front

Which organisms perform photosynthesis?

Back

Only Autotrophs.

Front

What are the two main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is produced during the light reactions of photosynthesis?

Back

ATP and NADPH, which are used in the Calvin cycle.

Front

What is the Calvin cycle?

Back

A series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

How does temperature affect the rate of photosynthesis?

Back

The rate of photosynthesis increases with temperature up to a certain point, after which it decreases.

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.
