What do plants need for the photosynthesis process?

• a camera and tripod
• light, carbon dioxide, and water
• roots, flowers, and bees
• soil, air, and oxygen

What are the reactants of photosynthesis?

• carbon dioxide and oxygen
• water and oxygen
• carbon dioxide and water
• water and glucose

What are the products of photosynthesis?

• water and carbon dioxide

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the stem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

How does carbon dioxide get into the leaves of a plant?

• It's absorbed by the roots
• It's made in a chemical reaction in the stem
• It enters through the stomata
• It goes through the flowers
