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.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are the light-dependent reactions?

Back

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

Front

What are the light-independent reactions (Calvin Cycle)?

Back

The light-independent reactions, also known as the Calvin Cycle, occur in the stroma of chloroplasts and use ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is the significance of glucose in plants?

Back

Glucose serves as an energy source for plants and is used to build other carbohydrates, such as starch and cellulose, which are essential for growth and structure.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are light energy, carbon dioxide, and water.

Front

Why is oxygen considered a byproduct of photosynthesis?

Back

Oxygen is considered a byproduct of photosynthesis because it is produced during the process but is not used by the plant; instead, it is released into the atmosphere.

Front

How does photosynthesis impact the environment?

Back

Photosynthesis plays a crucial role in the environment by producing oxygen, which is essential for the survival of aerobic organisms, and by removing carbon dioxide from the atmosphere.

Front

What is the equation for photosynthesis?

Back

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