Identify epithelial tissue.
Compare and contrast epithelium with deeper tissues.
Notice differences in the size, shape, and texture of cell nuclei.
Notice differences in the amount, color, and texture of cell cytoplasm.
 Slide 58 [trachea].

thickness.
o Find non-epithelial tissue.
o Find at least two different types of cells, with markedly differing appearances.
 Note size, shape, and texture of nucleus.
 Note amount, color, and texture of cytoplasm.
