Introduction: Why Cell Communication Matters Cell signaling enables organisms to coordinate activities, respond to environmental changes, and maintain homeostasis. Chapter 11 explains the universal mechanisms underlying local and long-distance cell communication, signal transduction, and programmed cell death. Types of Cell Signaling Local Signaling: Direct Contact: Cells communicate via ce...
