B. 3. Light microscopy (LM) versus electron microscopy (EM): Circle the correct statement.
A. LM gives sharper pictures at higher magnification.
B. EM, not LM, shows details within cells.
C. Both EM and LM give colored images (pink from eosin and purple from hematoxylin, for example).
D. EM does not use sectioned-tissue slices, only whole, preserved tissue.

B. 4. Which of these cell structures is attached to the glycocalx (cell coat)?
A. glycosome (glycogen granule)
B. sarcolemma (plasmalemma of a muscle cell)
C. nucleolus
D. nuclear envelope
E. lipid droplet
C. 5. Use logic and what you already know to answer this: One of our cellular organelles contains its own DNA and 37 genes that are much more similar to those of bacteria than to the ordinary genes in the nucleus of any kind of animal cell. That organelle is the . . .
A. rough endoplasmic reticulum
B. smooth endoplasmic reticulum
C. mitochondrion
D. lysosome
E. ribosome
A. 6. Choose the WRONG statement about the cell structures.
A. The part of the cell skeleton (cytoskeleton) that resists tension is elastin (elastic fibers).
B. A cell that contains especially abundant rough ER is a goblet cell.
