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 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 the process of photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

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 in the form of ATP and NADPH.

Front

What are light-independent reactions (Calvin Cycle)?

Back

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

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including the light-independent reactions of photosynthesis.

Front

What is NADPH and its function in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a reducing agent that provides the high-energy electrons needed for the Calvin Cycle to synthesize glucose.

Front

How does carbon dioxide concentration affect photosynthesis?

Back

Increasing carbon dioxide concentration generally increases the rate of photosynthesis, up to a certain point, after which other factors may become limiting.

Front

What is the effect of light intensity on photosynthesis?

Back

Higher light intensity increases the rate of photosynthesis, but only to a certain level; beyond that, other factors like CO₂ or temperature may limit the process.
