10. Plant roots absorb water and minerals from the soil. What does "absorb" mean?

• to release

• to send

• to take up or in

• to let go

Zane knows that plants use materials in the environment-soil, water or air-for their growth. He thinks plants probably use the soil to grow bigger, so he tests the idea with an experiment.

11. Zane puts a plant in a pot with soil. At the start of the experiment, he records how much the plant weighs. He also records how much the soil weighs. Zane adds water to the soil.
    

    Then, Zane lets the plant grow for a few weeks. At the end of the experiment, he weighs the plant and the soil again. His results are shown in the picture.

12. What did Zane find in his experiment? Select all the TRUE statements.

• The plant weighed the same at the start and end of the experiment.

• The plant weighed more at the end of the experiment.

•  The soil weighed the same at the start and end of the experiment.

• The soil weighed less at the end of the experiment.

Using only the information from his soil experiment, what can Zane say about plants and their growth?

• 1. Plants use material from the soil to grow bigger and heavier.

• 1. Plants do not use material from the soil to grow bigger and heavier.

• 1. Plants do not use material from the air to grow bigger and heavier.

Zane knows that plants have tiny openings in their leaves so that air can center into the plant. This makes him wonder if plants use the material from the air to grow bigger. But, Zane isn't sure if air even weighs anything.

Zane sets up a balloon experiment to test if air weighs anything. He sets up a balance scale with an equal number of balloons on each side. On one side the balloons are inflated with air. On the other side they are deflated—without any air. The side with inflated balloons pulls down.

Which of the following statements is true about what Zane discovered?

• The experiment shows that air has weight. This shows that air can contribute to the weight of a tree.

• The experiment shows that air is needed for a plant to be healthy. This shows that air is needed for a plant to survive.

• The experiment shows the process of how air can get into a plant. This shows that air can contribute to the weight of a tree.
