Plant Physiology: Exploring Cell Functions and Metabolism in Botany
This course in Plant Physiology (Bot. 271) at King Saud University delves into the intricate functions of cell components, water relations, mineral nutrition, phloem transport, photosynthesis, and more. Taught by Dr. Abdel-Rhman Z. Gaafar, students will gain insights into the complex world of plant biology, including topics such as phytohormones, protein metabolism, and growth regulation. Through lectures, exercises, and practical sessions, students will develop a deep understanding of plant physiology and its practical applications in botany and microbiology.
