Mushrooms are a type of fungus. What characteristic of fungi makes them different from plants?

• Fungal cells are eukaryotic

• Fungi are multicellular

• Fungi are heterotrophic.

• Fungi have cell walls.

The Florida Panther was once considered to be a subspecies of cougars and given a special trinomial taxonomy of Puma concolor coryi. Current scientists however, have studied the Florida Panther and removed the subspieces classification to only Puma concolor. Which of the following would most likely explain why the classification of the Florida Panther changed.

• New genetic evidence suggests a much closer relationship between the Florida Panther and other cougars.

• Shared features between the Florida Panther and other cougars were also found in newly discovered organisms in the world.

• Advanced technologies have shown a large difference in cell structure between the Florida Panther and other cougars

• Trinomial naming conventions are no longer used by longer used by scientists because only the genus and species are important in taxonomy.

In 1990, Carl Woese introduced the three domain system for classifying living things, after the advancement of DNA analysis allowed for a comparison of species genetic code. Which of the following is the best explanation for why domains were added to the previous system of classification?

• The old system of classification was wrong and needed to be corrected.

• New species are evolving too quickly to keep up with the old system of classification.

• Domains have always been included, they were just made official recently.

• Some organisms, which were previously characterized together, were determined to be genetically very different.

• Both protists and bacteria can be motile.

• Both protists and bacteria are microorganisms.

• Protists are eukaryotes, while bacteria are prokaryotes.

• Protists may be photosynthetic, but bacteria cannot be photosynthetic.

Terrestrial plants have stomata on the surface of their leaves. Stomata are 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 plants?

• 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 reproduction.

What is the main function of leaves?

• Leaves provide support for growth and a place to store food.

• Leaves provide a place for photosynthesis to occur

• Leaves absorb water and minerals and transport nutrients to the stem.

• Leaves create a barrier that prevents water in the plant's tissues from evaporating.
