How do plants obtain carbon dioxide for photosynthesis?

• From the soil

• Through their roots

• By absorbing sunlight

• From the atmosphere through stomata

What role does sunlight play in photosynthesis?

• It helps the plant absorb water

• It provides energy for the chemical reaction

• It produces carbon dioxide

• It heats the plant

What happens to the oxygen produced during photosynthesis?

• It is converted into carbon dioxide

• It is stored in the leaves

• It is used to absorb more sunlight

• It is used in cellular respiration
