What are the byproducts of respiration?

• Sugar and starch

• Oxygen and sugar

• Carbon dioxide and water

• Water and oxygen

What happens to the sugar produced during photosynthesis?

• Released into the air

• Used for respiration and some is stored as starch

• It is all stored as starch

• Converted entirely into oxygen
