Spring Final Review 3/5

Terrestrial plants have stomata on the surface of their leaves. A single stoma is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in the plant?

• Water enters the plant through the surface of the leaf for transpiration.

• Gases for photosynthesis are exchanged through the surface of the leaf.

• Energy for cellular reproduction is absorbed through the surface of the leaf.

• Carbon dioxide enters the plant through the surface of the leaf for cellular respiration.

From the paragraph above, this relationship is an example of

• predation

• mutualism

• commensalism

• parasitism

What is produced during transcription?

• mRNA.

• DNA.

• tRNA.
