1) Reed is working on a project about classifying cells as either prokaryotic or eukaryotic. He made a drawing of the cell that he observed under an electron microscope and he labeled its parts. Reed’s labeled drawing is shown. How should Reed classify this cell? a) As a prokaryotic cell b) As a eukaryotic cell c) There is not enough information to classify this cell d) This cell has components of both types of cells 2) What characteristics would you expect the organism in the diagram to possess? a) multicellular, eukaryotic cells with cell walls, are classified as a decomposer b) unicellular, eukaryotic cells without cell walls, are classified as a producer c) multicellular, prokaryotic cells with cell walls, are classified as a decomposer d) unicellular, prokaryotic cells with cell walls, are classified as a producer 3) Coal power plants supply a large amount of energy to the United States. For every pound of coal burned, only about 20 percent of the energy released is transformed into electrical energy that can be used to supply energy to homes and businesses. What happens to the rest of the energy released when coal is burned? a) It remains trapped in the coa b) It is reused in the power plant. c) It escapes as heat and light. d) It is transformed into geothermal energy. 4) Plant and animal cells have many similarities and differences. They have enough similarities that they are classified into the same domain. What characteristic do they share that classifies them both into the Eukarya domain? a) They both form multicellular creatures. b) They both have a cell wall. c) They both contain nuclei in their cells. d) They both produce their own energy. 5) Living things have been organized into ldifferent categories to make it easier to identify them. The diagram represents the organizational structure of living things. What goes on top of Kingdom? a) Multicellular b) Domain c) Unicellular d) Fungi 6) What basic characteristic divides the organisms in the column of animals is Kingdom B and plants are Kingdom A? a) The organisms in Kingdom A are all multicellular and those in Kingdom B are unicellular. b) The organisms in Kingdom A are all unicellular and those in Kingdom B are multicellular. c) The organisms in Kingdom A are all autotrophic and those in Kingdom B are heterotrophic. d) The organisms in Kingdom A are all heterotrophic and those in Kingdom B are autotrophic. 7) Riley is working on a project about classifying cells as either prokaryotic or eukaryotic. He made a drawing of the cell that he observed under an electron microscope and he labeled its parts. Riley’s labeled drawing is shown. How should Riley classify this cell? a) As a prokaryotic cell b) As a eukaryotic cell c) There is not enough information to classify this cell d) This cell has components of both types of cells 8) Gravity can be defined as a force of attraction between objects. The effects of gravity can be witnessed in many systems. Which of these actions is an example of gravity influencing other systems? a) surface water evaporating into the atmosphere b) planets moving around the Sun in an elliptical pattern c) glaciers melting because of increasing temperatures d) groundwater moving to the surface in an artesian well 9) The planets of the solar system travel in orbits but at different speeds. The reason that they travel at different speeds is that the Sun — a) does not exert tension on any of the planets. b) exerts a different amount of air resistance on each planet. c) exerts a different amount of gravitational force on each planet. d) does not exert electromagnetic force on any of the planets. 10) Scientists believe that all life on Earth is related and probably comes from a single ancestor. Which of the following contributes to the theory that all life comes from a similar ancestor? a) All life can perform photosynthesis b) All life has the ability to think c) All life is made from cells d) All life has the ability to communicate 11) Viruses are not considered living organisms because they are not composed of — a) DNA b) protein c) cells d) RNA 12) What do the dog, mushroom and a fish have in common? a) all perform photosynthesis b) all are composed of cells c) all are omnivores d) all are animals 13) Identify and choose the prokaryotic cell from the diagrams below. a) b) c) d) 14) The drawing was sketched by a student who was observing cells under a microscope. Which of the following characteristics would identify this cell as eukaryotic? a) Absence of a cell membrane b) Presence of flagella c) Presence of a nucleus d) Absence of a cell wall 15) Biologist are continually looking at the variety of life on Earth and trying to determine the best way to group it based on different characteristics. Recently, biologists have divided all life into three main groups, called domains. What are the three domains? a) plants, animals, and bacteria b) prokaryotic, eukaryotic, and viral c) archaea, bacteria, eukarya d) biotic, abiotic, viral 16) What do a mushroom, an amoeba, and a 6th grader have in common? a) They all belong to the Animal Kingdom. b) They are all composed of one or more cells. c) They are composed solely of gases and liquids. d) They are all classified as invertebrates 17) What is the best reason that fire is NOT considered a living organism? a) It requires oxygen to burn. b) It requires fuel to burn c) It can move from place to place. d) It is not composed of cells 18) The discovery of the cell was made possible by the invention of the microscope. In 1665, Robert Hooke first discovered and named the cell as he was observing dead plant cell walls of cork under a microscope. Over the next century Matthias Schleiden, Theodor Schwann, and Rudolph Virchow contributed to this work. Eventually, in 1839, the cell theory was formulated. It states that living organisms are composed of one or more cells, the cell is the basic unit of structure and organization in organisms, and cells arise from pre-existing cells. a) Only plants and animals are made of cells. b) Only animals are made of cells. c) All organisms are made of cells. d) Only Eukarya are made of cells. 19) The absence of which cell structure would indicate a cell is prokaryotic? a) Ribosomes b) Nucleus c) cell membrane d) cytoplasm 20) In which domain are humans classified? a) Archaea b) Bacteria c) Eukarya d) Fungi
