Abstract
Understanding the evolution and adaptations of plants is central to ecological and evolutionary biology. Plants have developed sophisticated strategies for survival, responding to changing environments through structural, physiological, and biochemical innovations. This study investigates plant evolution across geological timescales, focusing on major evolutionary milestones such as the transition from aquatic to terrestrial life, development of vascular tissues, reproductive innovations, and the evolution of complex photosynthetic mechanisms. Using paleobotanical data, genetic studies, and contemporary ecological observations, this study explores how plants have adapted to environmental challenges such as drought, predation, and nutrient limitations. Results indicate that the evolution of vascular systems and seeds were pivotal in plant colonization of land. Additionally, modern plants exhibit remarkable adaptive responses like xerophytic traits in arid environments and mutualistic relationships with fungi and insects. This study concludes that plant evolution is a dynamic process driven by selective pressures from both biotic and abiotic factors, leading to a diverse array of survival strategies that enable plants to thrive in varied environments.
