• water
• soil

7) Which statement is true about the plant pictured?

• It requires soil to grow.

8) How does soil help a plant? Select all that apply:

• It gives them the nutrients they need to survive.
• It helps them stand upright.

9) A student wants to design an experiment to test different conditions for growing plants. He places one plant in soil and an identical plant in water. Both plants receive the same amount of light. What results might you expect from this experiment?

• A plant in the soil will grow better than the plant in water.
• The plant in the water will grow better than the plant in the soil.
• The two plants will grow similarly well.
• Both plants will die because they need heat to survive.

10) The arrow is pointing to the part of a plant that ___________________________.

• takes in carbon dioxide
• absorbs nutrients from water
• soaks up heat from the sun
• produces food for the plant.
