Cell theory was first proposed in 1838. Evidence obtained through additional scientific
investigations resulted in the current cell theory. Which statement describes a component of the
original cell theory that was removed because of the new scientific knowledge?
Cells form through spontaneous generation
Which invention from the 17th century allowed for the development of modern cell theory?
The light microscope
A plant and an animal are both living things. According to the Cell Theory, what can you conclude
about these two very different organisms?
They are both made of one or more cells
The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow
resulted in the formation of the cell theory. Which of the following is not part of the cell theory?
All cells contain a nucleus
There are some similarities between prokaryotic and eukaryotic cells. Which of the following
structures is found in both prokaryotic and eukaryotic cells?
Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from
a low concentration to a high concentration.
Which of the following best describes the type of transport across the cell membrane?
Which type(s) of cells have genetic material that is contained in a nucleus?
both plant and animal cells
Which characteristic do most plants have in common?
they are autotrophic
Which cell structure is correctly paired with its primary function?
Ribosome- protein synthesis
The diagram below represents a cell of a green plant.
Solar energy is used to produce energy-rich compounds in which structure?
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases.
Which of the following has occurred?
The water in the gums has moved out due to the high concentration of salt in the solution.
Which organelle is the site where amino acids are synthesized into proteins?
Joy took the notes shown below while learning about cells.
• Forms boundary between a cell and the outside environment
• Controls the movement of materials into and out of the cell
• Consists of double layer of phospholipids
She forgot to write the name of the cell structure that her class was studying that day. What structure
is described in her notes?
Which of these best completes this concept map?
Look at the diagram of a cross-section of a cell membrane below.
The cell membrane controls movement of materials into and out of the cell.
The following particles are moving from high concentration to low concentration and are using a
carrier protein. How would you describe this type of movement across the membrane?
The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass
through. Because other substances are blocked from entering, this membrane is called
Osmosis occurs when there is a different concentration of solute molecules
on each side of the membrane. The drawing below shows a beaker containing
30% salt solution and a suspended cell containing a 10% salt solution.
What statement best describes the cell after 20 minutes?
A. Water will move from the cell into the beaker, resulting in a smaller cell.
Muscle cells are responsible for obtaining energy so the body can perform
voluntary and involuntary movement. Using you knowledge about
organelles and muscles, how would a muscle cell differ from other types of
The muscle cell would have more mitochondria than the other types of animal cells.
Cells found in plants and animals have similarities but can differ in function. Consider the
following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the
best explanation for the difference in the cellular vacuole size between these two biotic
The camel cells' have a small vacuole size because it does not need long term water and
The diagram below represents a cell.
