Chapter 29 Plant Diversity I How Plants Colonized Land Answers
How did plants first colonize land? The early ancestors of land plants were charophyceans, which evolved specialized characteristics that allowed them to live permanently above the waterline. These traits eventually led to the first plants on land, which opened up an expanse of terrestrial habitat. This habitat was rich in minerals and had few herbivores, making this ideal for plant evolution.
Plants also have special adaptations for specific land conditions. They have two types of vascular tissue, which allow them to store glucose differently than humans. Their specialized structures, such as roots and stems, allow them to live on land. They have evolved to make the most of their habitat. This evolution has resulted in a diverse range of plants, including the plants we know today. These plant groups include algae, non-vascular seed plants, and vascular nonseed plants. Each group has its own physiology, life history, adaptations to the land, and other characteristics.
