L.14.3 Cell Types and Microscopes

Why would a scientist use a transmission electron microscope (TEM) instead of a compound microscope to view a tissue sample?

• The TEM will produce an image with a higher resolution.

• The TEM allows viewing of individual atoms.

• The TEM image will be three-dimensional.

• The TEM is used for live samples.

Which microscope would be best to observe a living jellyfish?

• transmission electron microscope

• scanning electron microscope

• compound microscope

• dissecting/stereo microscope

Cells may be classified as either eukaryotic or prokaryotic. What is the difference between eukaryotic and prokaryotic cells?

• Eukaryotic cells are found in bacteria. Prokaryotic cells are not.

• Prokaryotic cells are found in plants and animals. Eukaryotic cells are not. 

• Eukaryotic cells contain DNA enclosed in a nucleus. Prokaryotic cells do not.

• Prokaryotic cells contain membrane-bound organelles. Eukaryotic cells do not.

The chart below compares the characteristics of four different cells.

Which cell most likely represents a plant cell?

• Cell W

• Cell X

• Cell Y

• Cell Z

Which statement best compares an animal cell to a plant cell?

• Both plant and animal cells have a large central vacuole.

• Both plant and animal cells perform cellular respiration.

• Both plant and animal cells perform photosynthesis.

• Both plant and animal cells have a cell wall.

Which cell structure is common in both prokaryotic and eukaryotic cells?

• cell capsule

• plasma membrane

• circular DNA molecule

• membrane-bound organelle

A student compares the structures found in two different cells.

Which of these best identifies both cells based on their structures?

• Cell 1 and Cell 2 are both eukaryotic.

• Cell 1 and Cell 2 are both prokaryotic.

• Cell 1 is eukaryotic and Cell 2 is prokaryotic.

• Cell 1 is prokaryotic and Cell 2 is eukaryotic.

Which cell structure is present only in a plant cell and NOT in an animal cell?

• central vacuole

• Golgi apparatus

• plasma membrane

• endoplasmic reticulum

Which set of structures can be found in many prokaryotic and eukaryotic cells?

• nucleus, mitochondria, cell wall

• nucleus, cell membrane, cell wall

• cell wall, cell membrane, ribosomes

• ribosomes, lysosomes, cell membrane
