Two students want to learn about plants. They observe two plants found in Florida. The students want to know how light affects leaves. The students make small holes in black construction paper. The students cover a leaf of the skunk vine plant and a leaf of the mimosa plant with the paper. The plants are placed near a sunny window for five days. The plants are watered during the five days. The plants are turned every day. On day five, the students remove the paper to look at the leaves. Their observations are recorded in the table below.

Why did the leaves of the mimosa plant become pale green after they were covered with black construction paper?

• Ⓐ

  The covered leaves could not take in air.

• Ⓑ

  The covered leaves could not obtain water.

• Ⓒ

  The covered leaves could not survive the heat.

• Ⓓ

  The covered leaves could not produce as much food.
