What are the products for photosynthesis?

• Oxygen and Water

• Oxygen and Carbon Dioxide

• Oxygen and Glucose (Sugar)

• Oxygen and Sunlight

What happens during photosynthesis?

• The cell uses glucose to make oxygen

• The cell uses the energy in sunlight to make food

• The cell uses oxygen to make food

In which of these does alcoholic fermentation occur?

• lactic

• yeast

• carbon dioxide

Carbon dioxide enters plants through the small openings in the leaf called the

• stomata

• chloroplasts

• pigments

How does photosynthesis benefit heterotrophs?

• It creates food that they can eat

• It creates clean water

• It adds carbon dioxide to the air

What happens during respiration?

• Water and carbon dioxide are converted into energy

• Oxygen is released into the air

• Glucose is broken down, releasing energy
