Bryophytes, commonly identified as mosses, form the simplest and oldest of the four plant classifications. The earliest mosses evolved from algae and so were adapted to living in an aquatic environment. As such, they had no vascular systems or roots, since all cells could extract water from their aquatic environment.ubmit. Some 475 million years ago, algae washed ashore into a moist, protected nook and developed as the first land plant. Since then, species have gone extinct and the very shape of the world has changed, but the plants have remained, adapting to each new challenge with increasing complexity and variety.
