Understanding Photosynthesis

What is photosynthesis?

• Photosynthesis is the process of respiration in animals.

• Photosynthesis is the method by which plants absorb nutrients from the soil.

• Photosynthesis is the process by which green plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

• Photosynthesis occurs only at night in plants.

Which organisms perform photosynthesis?

• Fungi, viruses, and mammals

• Insects, reptiles, and amphibians

• Plants, algae, and some bacteria

• Fish, birds, and worms

What do plants convert during photosynthesis?

• Nitrogen and sunlight into glucose and water

• Carbon dioxide and water into glucose and oxygen

• Glucose and sunlight into carbon dioxide and water

• Oxygen and minerals into carbon dioxide and glucose

What type of energy do plants use in photosynthesis?

• Sunlight

• Water

• Soil nutrients

• Carbon dioxide

What is the main purpose of photosynthesis?

• To produce oxygen for respiration.

• To absorb carbon dioxide from the atmosphere.

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

• To store energy in the form of fat.

Can algae perform photosynthesis?

• Only certain types of algae can perform photosynthesis.

• Yes, algae can perform photosynthesis.

• No, algae cannot perform photosynthesis.

• Algae primarily absorb nutrients from the soil instead of photosynthesizing.

What do plants produce as a result of photosynthesis?

• Nitrogen and glucose

• Oxygen and nitrogen

• Glucose and oxygen

• Carbon dioxide and water

Is sunlight necessary for photosynthesis?

• Yes, sunlight is necessary for photosynthesis.

• Photosynthesis occurs only at night.

• Sunlight has no effect on photosynthesis.

• Photosynthesis can happen without any light source.

What role do bacteria play in photosynthesis?

• Bacteria, especially cyanobacteria, perform photosynthesis by converting sunlight into energy, producing oxygen as a byproduct.

• Bacteria do not participate in photosynthesis at all.

• Bacteria only consume oxygen during photosynthesis.

• Bacteria produce carbon dioxide as a byproduct of photosynthesis.

How does photosynthesis help fuel a plant's metabolism?

• Photosynthesis produces oxygen, which is not used for metabolism.

• Photosynthesis provides glucose, which fuels a plant's metabolism.

• Photosynthesis creates water, which is essential for plant growth.

• Photosynthesis absorbs nutrients from the soil for energy.
