Photosynthesis Basics

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy, mainly from the blue and red wavelengths.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What gas is produced as a byproduct of photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis.

Front

Where does photosynthesis primarily occur in plants?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts.

Front

What is the function of the stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases, such as the intake of carbon dioxide and the release of oxygen.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of light-independent reactions in photosynthesis that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that occur in the thylakoid membranes, where sunlight is converted into chemical energy (ATP and NADPH).
