When a chemical signal from a group of embryonic cells causes a different, nearby group of cells to embark on a particular developmental course (say, differentiating into a leg), the interaction between the two groups of cells is called
A) induction.
B) coordinated differentiation.
C) implantation.

Question

Quizplus · Accepted Answer

The term "induction" refers specifically to the process by which one group of cells signals another group of cells to begin a particular developmental course. Coordinated differentiation is a more general term that could refer to any situation in which multiple groups of cells undergo distinct developmental trajectories in a coordinated manner, and implantation is unrelated to embryonic cell signaling.
