Plant Physiology Fundamentals: Life Processes and Metabolism

Plant physiology is the key to understanding how life works on Earth, exploring the complex mechanisms that allow plants to grow, thrive, and convert energy. This text-only course provides a comprehensive introduction to the core functions of plant systems. You will develop a solid conceptual framework for understanding processes like photosynthesis, respiration, water potential, and hormonal regulation, preparing you for higher-level biological sciences. What you'll learn: * Understand the principles of water relations and mineral nutrition, including absorption, translocation, and the role of essential elements. * Master the detailed steps of photosynthesis (light and dark reactions) and cellular respiration in plant cells. * Analyze the mechanisms of transport in plants, focusing on xylem and phloem function and the pressure flow hypothesis. * Learn the five major classes of plant growth regulators (hormones) and their influence on development, dormancy, and flowering. * Apply foundational knowledge of photoperiodism and vernalization to explain how plants respond to light and temperature cues. The content begins with defining key terminology and cellular structure before moving into detailed discussions of energy conversion, transport systems, and regulatory mechanisms. Each section includes written explanations and practice exercises to reinforce conceptual understanding. This course is designed for absolute beginners and students seeking a rigorous, systematic foundation in plant physiology for academic or professional preparation. No prior biological science knowledge is required. Start building your essential knowledge base in plant biology today.
