Water Plants

The diversification of life all began in the warm waters of Lujenar's oceans.  The first life forms were single celled organisms with very primitive structures.  After millions of year, these cells developed more complex structures to sustain life.

The Tanjen was one of the first microscopic eukaryotes to float freely in the open ocean of Lujenar.  It had a nucleus in its membrane and chloroplasts.  Sufficient sunlight allowed the Tanjen to sustain life through the process of photosynthesis.  

After floating around the shallow end of the oceans for millions of years, these early Tanjen cells slowly clumped together and became known as Bunchers.  The chloroplasts in these cells used water, carbon dioxide, and sunlight to make sugars which provided energy for growth.  Bunchers slowly evolved into two different forms, each adapted to their own environment.   
Through a long period of time, Bunchers developed tough ribbon-like structures to help them remain floating in the off shore waters.  The Freeler, approximately 11 inches long, was the new green plant evolved from Bunchers.  Central antenna-like leaves, the plant's special feature,  normally reached towards the surface to capture energy from the sun.  Small tiny red dots on the Freeler's surface allowed the plant to filter heat throughout its tissues.  The cells in these tissues contain chloroplasts to make sugar, water, and carbon dioxide which enabled Freelers to survive.  Freelers were abundant in the Lujenar's warm off shore waters even though sea creatures often ate them.  They were able to reproduce quickly because of such warm temperatures. They released little one-celled capsules that would float away and develop into new freelers.  
Moving to the rocky shores, Bunchers evolved holdfasts to allow them to cling to rocks.  The new plant called the Stickem had arm-like structures to hold the base of the plant in one place.  It could grow anywhere from 20 to 40 feet long.  Stickems reproduced vegetatively by breaking apart.  Stickems contained chloroplasts that make nourishing sugars from sunlight, water, and carbon dioxide.  The sticky substance on the Stickem's body protected it from many sea animals.  

Some Stickems were pulled out to the deep ocean.  In time, the Stickems adapted to its new environment by growing new structures.  Because the sea bottom was mostly sandy, there was nothing for the Stickems to hold onto.  They began to develop runners that grow through the sand and help hold the plant down.  The Tangler, as it became, also began to develop red bubbles on top of the leaves in order to absorb heat from above.  Because Lujenar's ocean isn't too deep, sunlight can still penetrate through the waters to help Tanglers synthesize their own food.   Tanglers became more brown through time.  Brown chlorophyll allowed them to live at greater depths.  The octopus-like leaves can tangle some of the the sea creatures that try to eat them.  Tanglers are about 10 to 20 feet tall.
