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 xylem

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

• The flowers capture water and deliver it to the leaves

Why do plants conduct photosynthesis?

• To make mitochondria
• To make glucose
• To release carbon dioxide
