All of the following characteristics are shared between plant and animal development except:
A)Gene expression in developing embryonic tissues is closely regulated.
B)Orientation of cells and tissues is critical for proper development.
C)Differentiation of cells is directed and maintained by cascades of signals.
D)Cell types,once determined,generally cannot change their differentiated characteristics.

Question

While all other options are characteristics shared by both plant and animal development, the ability for cell types to change their differentiated characteristics is unique to plant development due to the presence of totipotent cells, which can differentiate into any cell type. In animal development, cells typically lose the ability to differentiate into any cell type once they have taken on a specific differentiated state.
