INTERPRETING GRAPHICS
Biology students were working on a class project. They prepared copies of
transmission electron micrographs of a bacterium, a plant cell, and an animal cell
for display in their classroom. Unfortunately, the pictures were not labeled and got
mixed up. Help these students correctly identify the cells and cell structures. Use
the figures below to answer questions 1–5.
In the space provided, write the names of each cell’s labeled structures (A–I).
Using this information, write the identity of each cell—bacterium, plant cell, or
animal cell.
1. Cell 1 identity ___________________________________________________
A. _____________________________________________________________
B. _____________________________________________________________
C. _____________________________________________________________
2. Cell 2 identity ___________________________________________________
