which is not a fundamental concept addressed by cell theory?
cells may be classified as either prokaryotic or eukaryotic.
cells are the fundamental units of life.
modern cells evolved from a common ancestor.
all cells come from pre - existing cells.
all living organisms are composed of cells.

Explanation:

Cell theory has three main tenets: all living organisms are composed of cells, cells are the fundamental units of life, and all cells come from pre - existing cells. The idea that modern cells evolved from a common ancestor is related to evolutionary theory, not a core part of cell theory. Also, the classification of cells as prokaryotic or eukaryotic is a later - developed concept for categorizing cell types, not a fundamental concept of cell theory.

Answer:

A. Cells may be classified as either prokaryotic or eukaryotic.
C. Modern cells evolved from a common ancestor.
