**Lesson: Cell Communication** ------------------------------ ### **What is Cell Communication?** Cell communication is how cells talk to each other and respond to signals from their environment. This is important for things like growth, defense, and coordination within an organism. ### **How Do Cells Communicate?** Cells communicate using **signals** (like hormones or molecules) that travel to the cell's surface or inside the cell. These signals can be received through: 1. 2. ### **Types of Signals** 1. 2. ### **Steps of Cell Communication** 1. 2. 3. - - - 4. ### **Example: Ethylene in Plants** When ethylene, a plant hormone, binds to a receptor on a plant cell: 1. 2. 3. ### **Why Is Cell Communication Important?** - - - #### **Types of Signaling** - - - - #### **Signal Transduction Pathways** Signal transduction pathways are networks of molecules that relay signals from receptors to the final response. Key components include: - - - #### **Examples of Cell Communication** - - -
