Exploring the evolutionary journey of plants from algae to complex organisms, this overview delves into plant physiology, hormonal regulation, and adaptations that enabled the transition from aquatic to terrestrial life. It examines the development of vascular systems, the role of plant hormones in growth and response to stimuli, and the intricate anatomy and morphology that define plant life.
