Warm-Up Questions
______ 1. Samples of pond water taken over a six week period showed an increase in pH.
During the same period, observations of the pond showed an increasing amount of green water
plants covering the surface. Which cellular structure in the green plants is likely a contributing
factor to the increase in pH?
A.
B.
C.
D.
Chloroplast
Nucleus
Cell wall
Mitochondrion
______ 2. Plant cells and animal cells are classified as eukaryotic, rather than prokaryotic, due to
their unique features. All eukaryotic cells contain a nucleus and membrane bound organelles.
Eukaryotic cells are classified as either plant or animal cells, dependent upon which specific
organelles and/or features they contain. Which of the following is found in plant cells, but not in
animal cells?
A.
B.
C.
D.
Cell wall
Vacuole
Mitochondria
Endoplasmic reticulum
______ 3. In 1665, Robert Hooke was the first scientist to view cells under a microscope, using a
slice of cork. In the 1800s, scientist Theodor Schwann determined plants were composed of
cells. Soon after, scientist Matthias Schleiden concluded animals were also composed of cells.
Together these two scientists cofounded the Cell Theory. This theory is still recognized today
and includes Rudolph Virchow’s cell division discoveries. Which of the following is NOT one
of the main components of the cell theory?
A.
B.
C.
D.
All living things are made of cells
Cells can only come from other cells
Cells must contain DNA
Cells are the basic unit of life
______ 4. Four of the six kingdoms are comprised of organisms that contain eukaryotic cells.
Which of the following structures in a cell would NOT be evidence that the cell is eukaryotic?
A.
B.
C.
D.
Vacuoles
Mitochondria
Cell walls
Internal membranes
