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 is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

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 light-dependent reaction?

Back

The light-dependent reactions are the first stage of photosynthesis, where sunlight is captured and used to produce ATP and NADPH, and oxygen is released as a byproduct.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis, where ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide into glucose.

Front

What is the ultimate source of energy for photosynthesis?

Back

The ultimate source of energy for photosynthesis is the sun.

Front

What gas do plants absorb during photosynthesis?

Back

Plants absorb carbon dioxide (CO2) from the atmosphere during photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the respiration of most living organisms.

Front

How does photosynthesis impact the carbon cycle?

Back

Photosynthesis helps regulate the carbon cycle by removing carbon dioxide from the atmosphere and converting it into organic matter.
