Understanding Photosynthesis

What is the primary function of photosynthesis?

• To provide energy for cellular respiration.

• To absorb carbon dioxide from the atmosphere.

• To release oxygen as a waste product.

• The primary function of photosynthesis is to convert light energy into chemical energy in the form of glucose.

Which organisms are known to perform photosynthesis?

• Insects, reptiles, and amphibians.

• Plants, algae, and some bacteria.

• Fungi, viruses, and mammals.

• Mushrooms, yeast, and worms.

What are the main products of photosynthesis?

• Nitrogen and glucose

• Carbon dioxide and water

• Oxygen and carbon dioxide

• Glucose and oxygen

What is the role of chlorophyll in photosynthesis?

• Chlorophyll absorbs light energy for photosynthesis.

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll is a type of carbohydrate used in photosynthesis.

• Chlorophyll helps in the absorption of water for photosynthesis.

In which part of the plant does photosynthesis primarily occur?

• Flowers

• Stems

• Leaves

• Roots

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions (Calvin cycle)

• Photosynthesis and respiration

• Chlorophyll activation and oxygen release

• Light absorption and energy storage

How does sunlight affect the process of photosynthesis?

• Sunlight is essential for photosynthesis as it provides the energy needed for the conversion of carbon dioxide and water into glucose and oxygen.

• Sunlight is harmful to plants and inhibits glucose production.

• Photosynthesis occurs only in the absence of sunlight.

• Sunlight decreases the rate of photosynthesis by blocking carbon dioxide.

What is the chemical equation for photosynthesis?

• 6O2 + 6H2O -> C6H12O6 + 6CO2

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• 6CO2 + 6O2 -> C6H12O6 + 6H2O

Why is photosynthesis important for life on Earth?

• Photosynthesis is important because it produces oxygen and is the foundation of the food chain.

• Photosynthesis is mainly responsible for water purification.

• Photosynthesis is crucial for producing heat for the planet.

• Photosynthesis is important because it absorbs carbon dioxide only.

How do environmental factors influence the rate of photosynthesis?

• Environmental factors such as light intensity, carbon dioxide concentration, temperature, and water availability significantly influence the rate of photosynthesis.

• Photosynthesis occurs only at night regardless of environmental factors.

• Soil quality has no effect on photosynthesis.

• Increased humidity always decreases the rate of photosynthesis.
