Laga's Land Plants

IN THE BEGINNING

The ancestoro of the land plants of Laga were multicelled green algae that have developed in the shallow waters of the oceans. The first cell to photosynthesize visible light was the "Chloroulva", which appeared 930 million years ago. Approximately 320 million years ago, simple green shoots were established on land. These primordial plants had simple water-conducting cells within their photosynthetic stems.

DEVELOPMENT OF PLANT LIFE

The exact relationship between the first plant life and the actual groups are not clearly understood. The primeval cell that originated the existence of the actual plants found in Laga was the "Chloroulva cell". As it was described in the water plants chapter, this cell was the primordial photosynthetic cell, with complete eukaryote characteristics. It has chloroplastids that contained the pigment chlorophyll, which allowed the photosynthesizing of the visible light coming from the sun Kadesh.
We have explained in previous chapters the clustering process of the chloroulva cells. These colonies first developed in the shallow waters and then, due to adaptive processes began to populate the beaches and surrounding land. Perhaps the same process had occurred in the areas near to freshwater lakes and rivers. Up to this point the primordial plants were nonvascular, i.e. they didn't have the tubules that carry water and dissolved minerals ions needed for survival, but they began to develop a primordial root system that provided the necessary life nutrients. The first nonvascular plant was the "Calendula flotus" described in the chapter for Water Plants.
Up to this point the only mechanism for moving the necessary materials were diffusion and osmosis, such as the one found in the earthly mosses and liverworts. The development of the primordial root system allowed the early plant to move inland. It was probable at this time that the primordial vascular tissues began to develop.
The development of vascular tissues allowed primitive plants to shoot upward to utilize better the light energy. Up to this point we believe that Laga's primeval plants did not have a distinction between xylems and phloems. Xylems are the vascular tissues that transport water and dissolve mineral ions, and phloem transports sugars and other photosynthetic products. The environmental conditions of Laga began to stabilize diminishing the effects of UV radiation and the water vapor canopy began to recede and give way to a more gaseous atmosphere.
With the stabilization of the atmosphere and the development of true vascular tissues, plants began to move upward, and to develop larger and better shaped roots and stronger shoots. The atmosphere became richer in oxygen and the carbon-nitrogen cycle began to stabilize.
