Understanding Photosynthesis

What is photosynthesis?

• Photosynthesis is the process by which green plants convert light energy into chemical energy.

• Photosynthesis is the process of respiration in animals.

• Photosynthesis occurs only in the presence of water and soil nutrients.

• Photosynthesis is the method by which animals convert food into energy.

Which organisms perform photosynthesis?

• Insects, reptiles, and fish

• Plants, algae, and some bacteria

• Fungi, viruses, and mammals

• Mushrooms, worms, and protozoa

What are the main ingredients needed for photosynthesis?

• Carbon monoxide, water, and soil

• Oxygen, nitrogen, and glucose

• Sunlight, nitrogen, and minerals

• Sunlight, carbon dioxide, and water

What is the role of sunlight in photosynthesis?

• Sunlight is harmful to plants during photosynthesis.

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

• Sunlight is used to absorb nutrients from the soil.

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

What gas do plants take in during photosynthesis?

• Oxygen

• Carbon dioxide

• Nitrogen

• Hydrogen

What do plants produce as a result of photosynthesis?

• Carbon dioxide and water

• Oxygen and nitrogen

• Nitrogen and glucose

• Glucose and oxygen

How does photosynthesis benefit the environment?

• Photosynthesis increases carbon dioxide levels.

• Photosynthesis benefits the environment by reducing carbon dioxide levels, producing oxygen, and supporting the food chain.

• Photosynthesis produces harmful gases.

• Photosynthesis has no impact on the food chain.

Can photosynthesis occur without water?

• Yes, photosynthesis can occur with minimal water.

• Photosynthesis can occur using only carbon dioxide.

• No, photosynthesis cannot occur without water.

• Photosynthesis requires sunlight but not water.
