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 primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy, primarily from the blue and red wavelengths.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is glucose and why is it important?

Back

Glucose is a simple sugar produced during photosynthesis that serves as an energy source for plants and is used in cellular respiration.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy required to drive the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose and oxygen.

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 water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in photosynthesis that is fixed during the Calvin cycle to produce glucose.

Front

What is the significance of oxygen produced in photosynthesis?

Back

Oxygen produced during photosynthesis is released into the atmosphere and is essential for the respiration of most living organisms.
