Environmental Regulation of Plant Growth and Development Explained | Chapter 19 of Plant Physiology and Development Chapter 19 of Plant Physiology and Development examines how environmental factors shape plant growth through their influence on cell division, expansion, differentiation, and hormone signaling. Plant growth is not fixed; it is a flexible, responsive process governed by both internal regulatory mechanisms and external environmental cues. This chapter reveals how plants integrate signals such as water availability, temperature, light, gravity, and mechanical forces to control growth rates, tissue elongation, and overall architecture. The full lecture below provides a guided and accessible breakdown of these concepts. Watch the full chapter explanation here: Fundamentals of Plant Growth Plant growth is driven by three interconnected processes: Cell division – increases cell number Cell expansion – enlarges cell size through turgor-driven elongation Cel...
