Photosynthesis

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 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 primary purpose of photosynthesis?

Back

The primary purpose of photosynthesis is to produce glucose, which serves as an energy source for plants.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the red and blue wavelengths, which is essential for the light-dependent reactions.

Front

What are NADPH and ATP?

Back

NADPH and ATP are energy carriers produced during the light-dependent reactions of photosynthesis, used in the light-independent reactions.

Front

During which stage of photosynthesis is glucose produced?

Back

Glucose is produced during the light-independent stage, also known as the Calvin Cycle.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in the Calvin Cycle, where it is fixed into organic molecules to form glucose.

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis, where light energy is converted into chemical energy (ATP and NADPH) in the thylakoid membranes.

Front

What is the light-independent reaction?

Back

The light-independent reaction, or Calvin Cycle, is the second stage of photosynthesis, where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in the light-dependent reactions, where it is split to release oxygen and provide electrons.
