Final answer:
Homogeneity describes the condition where all cells in a tissue or group appear and function similarly, unlike the process of differentiation which leads to specialized cell structures and functions.
Step-by-step explanation:
The term that is described as "normal cell functioning where all cells look alike" is Homogeneity. This refers to the condition where cells within a particular tissue or group are similar in appearance and function. On the other hand, differentiation is a process where cells become specialized in their structure and function. The unique genetic expression of each cell type dictates its specific role and characteristics in the body. In contrast, dysplasia refers to abnormal cell growth, and metastasis is the spread of cancer cells from one part of the body to another.
