Chapter 6: Tour of the Cell

One primary advantage of light microscopy over electron microscopy is that:

• light microscopy provides for higher magnification than electron microscopy

• light microscopy provides for higher resolution than electron microscopy

• light microscopy allows the visualization of dynamic processes in living cells

• light microscopy provides for higher contrast than electron microscopy

Which of the following would be the most appropriate method to observe movements of condensed chromosomes during cell division?

• a hand lens (magnifying glass)

• standard light microscope

• scanning electron microscope

• transmission electron microscope

Which of the following would be most appropriate method to observe three-dimensional structure and organization of microvilli on an intestinal cell?

• a hand lens (magnifying glass)

• standard light microscope

• scanning electron microscope

• transmission electron microscope

Which of the following would be the most appropriate method to observe and measure the size of ribosomes in a eukaryotic cell?

• a hand lens (magnifying glass)

• standard light microscope

• scanning electron microscope

• transmission electron microscope

A newly discovered unicellular organism isolated from acidic mine drainage is found to contain a cell wall, a plasma membrane, two flagella, and peroxisomes. Based just on this information, the organism is most likely:

• a nonmotile prokaryote

• a motile bacterium

• a motile archaea

• a nonmotile eukaryote

• a motile eukaryote

Which of the following is a major difference between eukaryotic cells and prokaryotic cells?

• Prokaryotic cells have cell walls, while eukaryotic cells do not

• Eukaryotic cells have flagella, while prokaryotic cells do not

• Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not

• Prokaryotic cells are generally larger than eukaryotic cells

Which structure is common to plant AND animal cells?

• chloroplast

• central vacuole

• mitochondrion

• centriole

Which of the following are found in plant, animal, and bacterial cells?

• mitochondria

• ribosomes

• chloroplasts

• endoplasmic reticulum
