Plant Growth and Development: Hormones and Environmental Responses

How do plants know when to bend toward light, shed their leaves, or begin flowering? Understanding the chemical messengers and environmental cues that dictate plant behavior is key to mastering plant physiology. This course guides you through the core mechanisms of plant development, focusing on phytohormones, photoperiodism, and growth movements. You will gain a clear, structured understanding of plant biology, enabling you to explain how plants adapt to their surroundings at a cellular and organismal level. What you'll learn: - Understand the core functions and signaling pathways of major plant hormones, including auxins, gibberellins, and abscisic acid - Analyze how plants perceive and respond to light and gravity through phototropism and gravitropism - Explain the mechanisms of photoperiodism and vernalization in regulating flowering cycles - Explore modern agricultural applications of plant growth regulators in crop management - Define the biological processes of seed dormancy, germination, and senescence Starting with foundational biochemistry definitions, you will progress from individual hormone functions to complex environmental interactions, concluding with practical scenarios in modern plant science. This text-only course is designed for beginning biology students, plant enthusiasts, and curious learners, requiring no prior advanced science background.
