Plant Cell Walls: Structure, Composition, and Their Role in Growth and Defense | Chapter 3 of Plant Physiology and Development
Plant Cell Walls: Structure, Composition, and Their Role in Growth and Defense | Chapter 3 of Plant Physiology and Development Chapter 3 of Plant Physiology and Development explores the remarkable complexity and dynamic nature of plant cell walls. Far from being rigid barriers, cell walls are living, responsive structures essential for growth, communication, and protection. This chapter introduces the molecular architecture of primary and secondary walls, details the synthesis and arrangement of cellulose microfibrils, and explains how wall components interact to regulate mechanical strength and plasticity. To deepen your understanding, watch the full Last Minute Lecture summary below. Watch the full chapter breakdown here: The Fundamental Roles of Plant Cell Walls Cell walls give plants their structural integrity, define cell shape, and regulate the balance between rigidity and flexibility required for growth. Because plants lack internal skeletons, the cell wall assumes a ...
