Cell Structures & Cell Transport

Which cell function is most directly dependent on the cytoskeleton?

• transport of material inside the

  cell

• response of the cell to external

  pathogens

• storage of energy in stable long-

  term forms

• direction of cellular activity

Which structure does a virus have in

common with a prokaryotic cell?

• cell wall

• nucleic acid

• ribosome

• capsid

All cells, prokaryotic and eukaryotic, have a few common features. Which cell feature is found in both prokaryotic and eukaryotic cells?

• ribosome

• chloroplast membrane

• nucleus

• endoplasmic reticulum

Which of these is found in both

prokaryotic and eukaryotic cells?

• vacuole

• nucleiod

• mitochondrion

• cytoplasm

Which condition must be fulfilled in order for a virus to reproduce?

• A virus must have completed

  internal replication of its DNA.

• A virus must be absorbed by a

  living cell.

• A virus must store a surplus of

  tRNA and amino acids.

• A virus must have taken over the protein production resources of a host cell.

Which of the following is an example

of a prokaryotic cell?

• bacterial cell

• fungal cell

• plant cell

• animal cell

An animal cell that lacks a rough endoplasmic reticulum would be unable to perform which function?

• storing water

• producing proteins

• maintaining shape

• generating energy

Which option accurately differentiates

prokaryotes from eukaryotes?

• Prokaryotes do not have

  cytoplasm.

• Prokaryotes do not undergo

  cell division.

• Prokaryotes do not

  synthesize proteins.

• Prokaryotes do not have

  membrane-bound

  organelles.

Scientists claim that viruses are not

living. Which evidence supports the

classification of viruses as nonliving?

• Viruses are unable to change

  or evolve over time.

• Viruses must use their host's

  cellular machinery in order to

  reproduce.

• Viruses cause many different

  types of diseases.

• Viruses lack genetic material

  that can be passed to future

  generations.

This is a nonliving component of a

plant's structure made primarily of

cellulose.

• cell membrane

• cell wall

• chloroplast

• nucleus
