Photosynthesis Review

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.

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

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 needed to drive the photosynthesis process, specifically in the light-dependent reactions.

Front

What is produced as a byproduct of photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the main purpose of the Calvin cycle?

Back

The main purpose of the Calvin cycle is to convert carbon dioxide into glucose using the energy produced in the light-dependent reactions.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is the significance of glucose in photosynthesis?

Back

Glucose serves as an energy source for plants and is used to build other organic compounds.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.
