Explanation:
The plants and algae evolved from a common ancestor and studies have also found that the algae-like Chara also evolved into plants.
The plants became adapted to grow in the terrestrial habitat by modifying themselves. The modification was that they developed the vascular system which helps them in conduction of the nutrients and water from the soil to the top of the plants and also the food to every part of the plant.
