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 are the raw materials needed for photosynthesis?

Back

The raw materials for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the main products of photosynthesis?

Back

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

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 and oxygen.

Front

How does carbon dioxide concentration affect the rate of photosynthesis?

Back

As carbon dioxide concentration increases, the rate of photosynthesis typically increases until it reaches a saturation point.

Front

What happens to the rate of photosynthesis if light intensity increases?

Back

Increasing light intensity generally increases the rate of photosynthesis, up to a certain point where other factors become limiting.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily in the blue and red wavelengths, which is essential for photosynthesis.

Front

What is the chemical formula for glucose?

Back

The chemical formula for glucose is C6H12O6.

Front

What is the effect of temperature on photosynthesis?

Back

Photosynthesis rates generally increase with temperature up to an optimal point, beyond which the rate may decline due to enzyme denaturation.
