Water is an essential component of plant life. Twylo is a water planet. It is 85% water. It would be surprising if aquatic plants weren't the predominant life forms on Twylo. The first plants on Twylo got their start in the waters of Twylo. Twylo water still to this day is the home of most of these plants. The water there still teems with microscopic plants that have changed little from their distant ancestors. On Twylo there are over 100,000,000 species of aquatic plants. These plants can be found in the oceans, seas, ponds, lakes, and rivers. Some of them live in fresh water, some are found in salt water. Some are single celled, others multicellular.
Twylo has a large variety of aquatic plants. One such plant is the Zoplamocapa. The Zoplamocapa is found deep in the oceans of Twylo. Zoplamocapae are very primitive and successful, being particularly abundant in deep dark areas of the ocean. This species of plant is made up of simple cells aggregated into loose colonies. The colonies may be embedded in a gelatinous matrix. It is bluish in color.
Throughout the world of Twylo there some 200,000 species of this plant. The plants can be rooted or free-floating and may grow their leaves and flowers above the water surface. They have small flowers that grow on long stalks to the surface. Some species have small flowers that bloom under the water surface.
Tyculacacease vary greatly in shape and size. They occur in many ecological areas from water to fields. The aquatic types at times have a small white flower. Their leaves are of two kinds, floating and submerged. Some types grow on dry land. The water types and the land types occupy separate habitats and have distinctive anatomical characteristics. The water types are generally large and covered with coarse hairs. They many have tendrils that help them climb to the water surface.
The Janphyta is single celled plant and is capable of independent existence. This plant can be found in the oceans of Twylo. The Janphyta have very little chlorophyll with which to convert light energy into chemical energy. The plant is more like a bacteria than like other ocean plants. They lack true organelles, have little or no power of movement and do not truly have sexual reproductive processes. This plant has the capacity to convert oxygen into carbon dioxide.
Twygrasses live in freshwater, ponds, lakes, and rivers. Most of them are rooted to the bottom, but some have no roots and receive all the nutrients they need from the water instead of the soil. They grow up out of the water and often form thick beds at the water's edge. Twygrasses have finely divided underwater leaves which are not damaged by the current. During the warm seasons this plant has white or rose-purple flowers that my be 1/2 foot in diameter. They grow on a weak stalk, 1 to 2 feet long, and rise only little above the water. The leaves spread out on the water's surface. The Twygrasses' ancestors originally left water and evolved on land, but as time went by they returned to a watery habitat.
The autumn produces underwater bulbs. Every autumn the leaves of the Autumna die, but the following Spring new leaves develop from buds. The young plant grows rapidly, producing only shallow roots. Flower buds appear in early Summer and by midsummer the flowers open, ready to be pollinated by insects. As soon as they have been pollinated, the flowers wither.
The Terwa is an example of an emergent water plant. It starts its annual cycle underwater but quickly reaches the surface and then moves to land. The plant can live both in the water and on the land. The flowers bloom about 2 feet above the leaves, where they attract pollinating insects.
