- Carbon, Hydrogen, Oxygen
- Oxygen, Helium, Calcium
- Nitrogen, Potassium, Zenon
Based on the data table, which area would have the best chance at having organiccompounds?
AArea 1
B Area 2
C Area 3
D Area 4
11 Corn is an organic compound. What are the main elements found in corn?

G FeO2 – iron oxide
H C8H9NO2 – acetaminophen
J H2SO4 – sulfuric acid
1 Living organisms are made up of cells. Cells are organized at different levels to formvery complex living organisms like your body. Each level has a specific role or job toperform.Which of the following lists these levels in the correct order of organization from thesimplest to the most complex?
A Cells, tissues, organs, organ systems, organisms
B Organisms, organ systems, organs, tissues, cells
C Tissues, cells, organs, organisms, organ systems
D Organs, organ systems, organisms, cells, tissues
3 Which phrase best describes the function of mitochondria?
A Located in the cytoplasm
B Bacteria-sized organelle
C Converts energy from food for cell use
D Contains a folded inner membrane
28 What is the purpose of mitosis?
F It guarantees that each daughter cell has half the amount of DNA of parent cells.
G It ensures that new nuclei have an exact copy of DNA.
H It ensures the reproduction of mitochondria and chloroplasts.
J It prevents the occurrence of cancer cells.
16 The primary function of a chloroplast is to —
F convert food into energy a cell can use
G control the functions of a cell and control genetic traits
H convert radiant energy into chemical energy through photosynthesis
J store water and nutrients
15 A student observing a sample of cheek cells noticed that all of the cells wereidentical. Which statement below explains why these cells are identical?
A Cheek cells are identical because they all come from the same location in thebody.
B Cheek cells are identical because all cells come from other cells through division.
C Cheek cells are identical because they do not have a cell wall.
D Cheek cells are identical because they have a chloroplast.
12 Which of the following statements accurately represents the differences in plant andanimal cells?
F Only plant cells have a cell wall, chloroplasts, and a vacuole.
G Only animal cells have a cell wall, chloroplasts, and a vacuole.
H Only plant cells have a cell membrane, mitochondria, and cytoplasm.
J Only animal cells have a cell membrane, mitochondria, and cytoplasm.
9 Which of the following do all living organisms have in common?
A They all have cells that are held up by cell walls.
B They all have the same way to get water and food into their cells.
C They all have cells.
D They all have special cells that can do many different things.
5 In all living organisms, the presence of what structure supports the cell theory? Youdrew this structure for all your slide drawings during the Cell Lab.
A Cell wall
B Cell membrane
C Vacuole
D Chloroplast
19 A scientist observes two cells. Cell 1 and Cell 2 both contain DNA (genetic material)and ribosomes. However, Cell 1 contains a nucleus and other membrane-boundorganelles, but Cell 2 does not contain a nucleus.
What is the correct classification for each of the cells?
A Cell 1 = Eukaryotic, Cell 2 = Prokaryotic
B Cell 1 = Prokaryotic, Cell 2 = Eukaryotic
C Cell 1 = Eubacteria, Cell 2 = Archaea
D Cell 1 = Archaea, Cell 2 = Eubacteria
18 In 1838 botanist Matthias Schleiden determined that all plants are composed of cells.In 1839 anatomist Theodor Schwann proposed that all animals are composed ofcells. In 1855 biologist Rudolph Virchow added to Schleiden’s and Schwann’sobservations and proposed that all living things are composed of cells. Whichstatement is also part of Virchow’s cell theory?
F All cells have a cell wall.
G All cells arise from pre-existing cells.
H All cells are capable of photosynthesis.
J All cells can develop into any other type of cell.
