Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, 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.

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

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process, allowing plants to convert carbon dioxide and water into glucose and oxygen.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

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.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.
