Final answer:
Unicellular organisms such as bacteria and yeast cells do not typically exhibit differentiation.
Step-by-step explanation:
Unicellular organisms such as bacteria and yeast cells do not typically exhibit differentiation. Differentiation refers to the process by which cells become specialized for specific functions. In multicellular organisms, differentiation allows for the formation of different types of cells, such as muscle cells or nerve cells. However, unicellular organisms generally do not have specialized cell types and perform all necessary functions within a single cell.
