Cell Quiz

The 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?

• All living things are made of cells

• All cells come from other preexisting cells.

• Cells form through spontaneous generation

• Cells are the basic structural and functional units of life

There are some similarities between prokaryotic and eukaryotic cells. Which of the following

structures is found in both prokaryotic and eukaryotic cells?

• lysosome

• mitochondrion

• nucleus

• ribosome

One way prokaryotes differ from eukaryotes is that they

• contain DNA, which carries biological information.

• have a surrounding barrier called a cell membrane.

• do not have a membrane separating DNA from the rest of the cell.

• are usually larger and more complex

How is a plant cell different from an animal cell?

• An animal cell has a cell membrane that allows certain substances to pass through

• An animal cell has a central vacuole for storing material

• A plant cell has a cell wall for support and protection

• A plant cell has ribosomes for assembling proteins

Bacteria are prokaryotic cells. By contrast, animal, plant, and fungal cells are eukaryotic. What is the MAIN difference

between prokaryotes and eukaryotes?

• Eukaryotes have a cell wall

• Prokaryotes cannot live without a host

• Eukaryotes copy DNA and are able to reproduce

• Prokaryotes do not have a membrane-bound nucleus

Which cell structure pairing is CORRECTLY paired with it’s function?

• ribosome- protein synthesis

• vacuole- cell division

• mitochondria- photosynthesis

• endoplasmic reticulum- contains DNA

If you examined a cell under a microscope and found it had a nucleus and other organelles, how would you classify the

cell?

• It is a plant cell

• It is an animal cell

• It is a eukaryotic cell

• It is a prokaryotic cell

In the past, some scientists accepted the theory of spontaneous generation. This theory states that organisms can arise

from nonliving matter. Now scientists generally accept cell theory to explain the origin and growth of new organisms.

Which of these statements is a key idea of cell theory that disproves the theory of spontaneous generation

• The cell is the basic unit of life

• All living things are made up of matter

• All cells arise from pre-existing cells by division

• All cells are formed from the combination of two other cells

Bacteria are prokaryotic cells, while multicellular and more sophisticated single-celled organisms are eukaryotic. Which

of these describes a prokaryotic cell and NOT a eukaryotic cell?

• Sunlight is absorbed by chloroplasts in the cell

• Molecules join together to assemble a permeable cell membrane

• The nuclear membrane disassembles and chromosomes align in a cell

• DNA is distributed loosely within the cell rather than in chromosomes

Different types of cells can have certain organelles and structures in common. Which types of cells definitely contain

cell walls?

• plant and animal cells

• plant and eukaryotic cells

• plant and prokaryotic cells

• animal and eukaryotic cells
