Understanding Photosynthesis

What is photosynthesis?

• Photosynthesis is the process by which green plants convert light energy into chemical energy in the form of glucose.

• Photosynthesis occurs only in the dark.

• Photosynthesis is the conversion of chemical energy into light energy.

• Photosynthesis is the process of respiration in animals.

Which organisms primarily perform photosynthesis?

• Insects, reptiles, and amphibians

• Plants, algae, and some bacteria

• Fish, birds, and mammals

• Fungi, viruses, and mammals

What are the main ingredients needed for photosynthesis?

• Carbon monoxide, sunlight, and soil

• Sunlight, carbon dioxide, and water

• Sunlight, nitrogen, and minerals

• Oxygen, nitrogen, and glucose

What role does sunlight play in photosynthesis?

• Sunlight is harmful to plants during photosynthesis.

• Sunlight is essential for providing the energy required for photosynthesis.

• Sunlight is only needed for plant growth, not photosynthesis.

• Sunlight is a byproduct of the photosynthesis process.

What is the chemical equation for photosynthesis?

• 6O2 + 6H2O -> C6H12O6 + 6CO2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• 6CO2 + 6H2O -> 6C6H12O6 + 6O2

What is produced as a result of photosynthesis?

• Carbon dioxide and water

• Glucose and oxygen

• Nitrogen and glucose

• Oxygen and carbon dioxide

How do plants absorb carbon dioxide?

• Via photosynthesis in the stems

• Plants absorb carbon dioxide through stomata on their leaves.

• Through roots in the soil

• By absorbing water from the air

What part of the plant is responsible for photosynthesis?

• Flowers

• Leaves

• Roots

• Stems

Why is photosynthesis important for life on Earth?

• Photosynthesis occurs only in the dark and does not require sunlight.

• Photosynthesis is only important for plants and has no impact on animals.

• Photosynthesis consumes oxygen and releases carbon dioxide.

• Photosynthesis is crucial for life on Earth as it produces oxygen and is the foundation of the food chain.

How does photosynthesis benefit humans?

• Photosynthesis decreases the amount of food available for humans.

• Photosynthesis provides oxygen and food, supporting human life and ecosystems.

• Photosynthesis has no impact on human health or the environment.

• Photosynthesis produces carbon dioxide, which is harmful to humans.
