Plants and algae most recently shared a common ancestor 480 million years ago, and plants colonized land shortly after that. Lig
ht, water, minerals, and dissolved gases surround the whole body of a submerged green alga, and the buoyancy of water provides physical support. What evolved in terrestrial plants to provide support and also transport water and minerals?
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.
The plants also added the deposition of the cutin layer over their structure which allows the plants to stand straight and few amounts of loss of water from the plants.
