Cell Wall Dynamics, Signaling Pathways, and Stress Responses Explained | Chapter 18 of Plant Physiology and Development Chapter 18 of Plant Physiology and Development examines the plant cell wall as a highly dynamic interface that senses environmental changes, mediates signaling, and supports adaptive responses to biotic and abiotic stress. Far from being a passive structure, the cell wall is continually remodeled to balance growth with protection. This chapter explores the receptors, enzymes, and molecular pathways that detect cell wall integrity, trigger immune responses, and regulate wall reinforcement. The full lecture below provides a clear, structured walkthrough of these processes. Watch the full chapter explanation here: The Cell Wall as a Dynamic Signaling Hub The plant cell wall is constantly remodeled to accommodate growth and respond to stress. Structural changes in the wall act as signals that activate defense pathways or trigger reinforcement. Plants monitor wa...

Cell Wall Structure, Remodeling, and Development Explained | Chapter 17 of Plant Physiology and Development Chapter 17 of Plant Physiology and Development provides an in-depth examination of the plant cell wall—one of the most essential and multifunctional structures in plant biology. Acting as both a protective barrier and a dynamic regulator of growth, the cell wall is a central player in plant physiology, development, signaling, and defense. This chapter highlights the biochemical components of primary and secondary walls, their biosynthesis, the enzymes that remodel them, and the sophisticated communication pathways that integrate cell wall status with plant growth and immunity. The full lecture below offers a clear and accessible walkthrough of these concepts. Watch the full chapter explanation here: Primary and Secondary Cell Wall Composition The plant cell wall is a composite structure composed mainly of cellulose, hemicelluloses, pectins, and structural proteins.
