Sooto has an interesting variety of land plants. They had their origins in the ocean. The first aquatic plants evolved on the water's surface where ambient light was in abundance. These one celled plants used sunlight and carbon dioxide to produce glucose for energy and oxygen as a waste product. The oxygen accumulated in Sooto's atmosphere, making it possible for land animals and plants to exist.
Aquatic plants had to develop true roots and leaves with an advanced vascular system. This enabled them to pull water and nutrients up through their roots and disperse photosynthetic products throughout their organism. The earliest land plants, Imeldaphytes, were low lying plants which grew in moist environments. They needed the moist environment because they lacked a true vascular system.
The next group of plants, the Strawlophytes, see the beginning of a vascular system enabling them to grow taller. These plants relied less on high moisture content and were able to spread around the planet. Soon, more advanced plants with more advanced vascular system, xylem and phloem, became abundant on Sooto.
