Bell Work EOC Review

Which invention from the 17th century allowed for the development of modern cell theory?

• light microscope

• xrays

• scanning electron microscope

• computers

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?

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

• All cells come from other living cells.

• All cells contain a nucleus.

• All living organisms are made of one or more cells.

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 are the basic structural and functional units of life.

• Cells form through spontaneous generation.

• All living things are made of cells.

• All cells come from other preexisting cells

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two very different organisms?

• Plants have cells but animals do not.

• They both come from a non-living organism.

• They both come from the same kind of cell.

• They are both made of one or more cells.

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

1. bacteria 2. viruses 3. eukaryotic 4. prokaryotic

• 3 and 4

• 4 only

• 1 and 2

• 3 only

Which of the following functions does active transport perform in a cell?

• equalizing the concentration of water inside and outside the cell

• distributing enzymes throughout the cytoplasm

• packaging proteins for export from the cell

• moving substances against a concentration gradient

Which characteristic do most plants have in common?

• they produce seeds

• they are prokaryotic

• they are unicellular

• they are autotrophic

There are some similarities between prokaryotic and eukaryotic cells. Which of the following structures is found in both prokaryotic and eukaryotic cells?

• mitochondria

• nucleus

• ribosomes

• lysosome

Which cell structure is correctly paired with its primary function?

• vacuole - cell division

• mitochondrion - movement

• nucleus - storage of nutrients

• ribosome - protein synthesis
