6.13AB - Unit Test Review

Tigers, sponges, and whales are all members of the animal kingdom. These organisms are very different but are similar in some ways. Which of the following is a characteristic used to classify these organisms as animals?

• They have fur.

• They eat other living organisms.

• They feed on decomposing organic matter.

• They have cell walls.

Which of the following organisms is most likely a prokaryote?

• A fungus

• An amphibian

• A plant

• A bacterium

What is the most basic difference between autotrophs and heterotrophs?

• Heterotrophs remain in one place, while autotrophs move around.

• Heterotrophs get nutrition by eating, while autotrophs make their own food.

• Heterotrophs respond to their surroundings, while autotrophs do not.

• Heterotrophs excrete waste products, while autotrophs do not.

What aspect of cell theory is shown in this image?

• Cells arise from existing cells.

• Only plants are made up out of cells.

• Cells are the basic unit of structure and function in living things.

• Only parts of plants are made up of cells.

The development of cell theory was begun by scientists who were observing which kind of cell?

• Cork cells

• Onion cells

• Cheek cells

• Cardiac cells

Tamara studies the living things in a forest ecosystem and classifies an organism as a heterotroph based on what she observes. Which of Tamara's observations would best support identifying it as a heterotroph?

• It needs water to survive.

• It eats insects and mice.

• It lives on the forest floor.

• It is composed of many cells.
