Photosynthesis

What do plants absorb from the soil that is essential for photosynthesis?

• Oxygen

• Nitrogen

• Water

• Carbon Dioxide

What are the two main reactants needed for photosynthesis?

• Oxygen and glucose

• Carbon dioxide and water

• Nitrogen and minerals

• Hydrogen and sulfur

What is the importance of photosynthesis to life on Earth?

• It produces oxygen and organic compounds for food.

• It absorbs carbon dioxide and releases nitrogen.

• It generates heat for the planet's atmosphere.

• It creates energy from inorganic materials.

What is the role of chloroplasts in plant cells?

• They are the site of photosynthesis.

• They store nutrients for the plant.

• They help in the absorption of water.

• They provide structural support to the cell.

What is taken in by the leaves of the plant to give the chloroplasts energy for food production?

• Water

• Sunlight

• Carbon Dioxide

• Nutrients

What are the raw materials of a chemical reaction located on the left side of a chemical equation?

• Products

• Catalysts

• Reactants

• Solvents

What is the byproduct of photosynthesis that is essential for human respiration?

• Carbon Dioxide

• Oxygen

• Nitrogen

• Hydrogen

What are the 'outputs' of a chemical reaction located on the right side of a chemical equation?

• Reactants

• Catalysts

• Products

• Solvents

What is the role of sunlight in photosynthesis?

• It provides the energy needed for the process.

• It absorbs carbon dioxide from the atmosphere.

• It helps in the formation of glucose directly.

• It cools the plant to prevent overheating.

What gas do plants release during photosynthesis?
