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 reactants of photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6), which serves as an energy source for plants.

Front

What role does chlorophyll play in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen, which is essential for the survival of most living organisms, and it forms the base of the food chain.

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 light-dependent reaction?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is the second stage of photosynthesis, where ATP and NADPH are used to convert carbon dioxide into glucose.
