Assessment for the Daisy Experiment

Assessment for the Daisy Experiment

Question 1 of 5

1

How do plants drink water?

Select one of the following:

  • Plants absorb water that rains from the sky through a process called absorption.

  • Plants drink water and it travels up the stem through a process called capillary action.

  • Water travels through the stem by a magnetic pull.

Explanation

Question 2 of 5

1

Why did the flower in the experiment change color?

Select one of the following:

  • Because the flower absorbed the dye in the water.

  • Because some of the dye accidentally dropped on the leaves

  • All flowers change colors after some time.

Explanation

Question 3 of 5

1

Bigger plants absorb water through a process called photosynthesis, in order to make sure that the water travels to the higher parts.

Select one of the following:

  • True
  • False

Explanation

Question 4 of 5

1

Chlorophyll is a green pigment that is present in all green plants and its responsible for the absorption of light to provide energy for photosynthesis.

Select one of the following:

  • True
  • False

Explanation

Question 5 of 5

1

How does capillary action occur?

Select one of the following:

  • There is a chemical action between the stem molecules and the water molecules that allow for them to create and exchange energy.

  • Water accumulates in the stem and so the water level gets higher within the stem.

  • Water molecules stick together and to the walls of the tube as they are climbing up the stem. They will continue to climb until gravity is too much.
