  1. It carries water and food around the plant · The stem acts like a highway, carrying water up and food back down through the plant.
  2. Soak up water and minerals from soil · Roots reach into the soil and soak up water and minerals, like a straw pulling a drink.
  3. True · That's right. Leaves use sunlight to cook up food for the whole plant.
  4. It travels up through the stem · The stem is the path water travels through the plant, all the way from the roots to the leaves.
  5. The roots · Roots sit underground and are built to soak up water from the soil right away.
  6. False · Flowers don't absorb water. Roots do that job down in the soil.
  7. Water and food could not move between the roots and the leaves · The stem carries water and food between the roots and leaves. Cut it, and that path breaks.
  8. Making food · Leaves need sunlight to make food. If they cannot catch light, the plant makes less food.
