If you compared a slide of an epithelial tissue to that of a connective tissue under a light microscope, which of these differences would you NOT expect to see?
A) The connective tissue would have widely spaced cells; the epithelial tissue would have tightly packed cells.
B) The epithelial tissue would line a surface; the connective tissue would not be a surface layer but may be closely associated with the surface epithelial layer.
C) The connective tissue would have an extensive network of blood vessels; the epithelial tissue would be avascular.
D) Connective tissue would have few cells compared to the amount of extracellular matrix (ECM); the epithelial tissue would have many cells relative to ECM.
E) The epithelial tissue may have a liquid ECM; connective tissues always have solid ECM.

Epithelial tissues do not have a liquid ECM; they have minimal ECM as the cells are tightly packed. Connective tissues can have various types of ECM, including liquid (as in blood), gel-like, or solid.
