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 main products of photosynthesis?

Back

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

Front

What is the chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What role does sunlight play in photosynthesis?

Back

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

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, and is essential for converting that energy into chemical energy.

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 limit the process.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis, providing electrons and protons needed for the formation of glucose.

Front

What organisms perform photosynthesis?

Back

Photosynthesis is primarily performed by plants, algae, and some bacteria.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while respiration releases carbon dioxide and water, which are used in photosynthesis.
