BIO 155 Exam 2 Actual study set with
Questions and correct/verified Answers
Which of the following organelles would only be found within a cell that was both eukaryotic and
autotrophic? - ANSWER-Chloroplast
After being formed by the ribosomes located on the endoplasmic reticulum, what is the next organelle
to which a protein could be transported? - ANSWER-Golgi apparatus
Which of the following help direct the movement of materials or organelles throughout the cell? -
ANSWER-all the choices are true
Which is NOT true about the cell theory? - ANSWER-the general concept of life is cellular still holds
because these organisms still utilize cells sometime in their life, but this shows that cell membrane
partitions can be abandoned.
Which is NOT a reason for the small size of cells? - ANSWER-The increased number of organelles requires
that eukaryotic cells be smaller than prokaryotic cells
A high powered microscope that produces an image from scattered secondary electrons is the -
ANSWER-SEM
A microscope that uses antibodies that glow to reveal the location of a protein in a cell is - ANSWER-
phase contrast light microscope
A microscope that uses antibodies that glow to reveal the location of a protein in a cell is the - ANSWER-
immuno microscope
Which statement is NOT true about bacteria ? - ANSWER-Their cell wall is made of a slime layer that is
the same as in plant cell walls
Which statement is NOT true about bacterial anatomy? - ANSWER-The glycocalyx sheath is located inside
the cell wall
An amino sugar called N-acetylmuramic acid is an important building block of the cell wall of some
bacteria. Penicillin prevents this amino sugar from being incorporated into the bacterial cell wall.
Therefore, - ANSWER-All of the choices are correct.
Most bacteria live in a solution that is
hypotonic relative to the cytoplasm of the bacteria. The cell wall of a bacterium is a peptidoglycan
polymer that is tightly cross-linked. This would therefore function to - ANSWER-provide a rigid wall that
prevents the cell wall from swelling
Which term is based on the Greek root words for "before" and "kernel"? - ANSWER-prokaryote
Which is NOT true of eukaryotic cells? - ANSWER-They contain ribosomes that are smaller than those of
prokaryotic cells.
Cells that do NOT produce cell walls are - ANSWER-animal cells
