    • Take in water and minerals from soil
    • Make seeds that grow into new plants

  3. Leaves use sunlight to help make food for the plant.

  2. Take in water and minerals from soil · Roots take in water and minerals dissolved in soil water.
  3. True · Leaves use energy from sunlight to make sugary food from water and carbon dioxide.
  4. It travels upwards through the stem · The stem provides a pathway for water to move from roots to leaves.
  5. The roots · Roots take in the soil water. It can then travel through the stem.
  6. False · A sunflower's seeds start to form in its flowers. Roots take in water and minerals.
  7. Water and food paths are broken · The cut breaks the pathways that carried water and food between the separated parts.
  8. Using sunlight to make sugary food · The covered leaves cannot use sunlight for food-making while the mud blocks that light.
