Question

Quizplus · Accepted Answer

One of the key characteristics of complex multicellularity is that interior cells are exposed to a different physical and chemical environment than exterior cells. This is because the exterior cells are in contact with the external environment while the interior cells are shielded from it by layers of other cells. This difference in environment leads to specialized functions and adaptations for both types of cells.
