Omar's Land Plants


 

            Early plants evolved in the oceans. The clear warm shallow water of Eucaliptus' oceans was the perfect place for microorganisms to develop. The first micro cells appeared about 2 billion years ego. Those very first organisms still exist today. They can be seen swimming in the ocean. 

            The cell above called, algebra, was the very first living organism on the planet. The ability of this cell to respond to light was the most important event. It  started to manufacture its own food, because it took advantage of the light of the sun. The cell multiplied itself  by  exponential growth  which means that if there was one cell  it became two cells, if there were 2 cells they became 4 cells, and so on. All living organisms on Ecaliptus are made up of cells. Plants are not the exception. Algebra is an oval in shape and it is so soft and fragile. It is usually very small so that it cannot be observed with the naked eye.  Algebra gave origin to early plants.

            The ability of Algebra to manufacture its own food allowed it to conquer the ocean floor. The buoyant force of water pushed large colonies of Algebra to the surface of the water. The cells then turned into different kinds of creatures. As they became more exposed to the light of the sun they grew what we called leaves.  The first plants called La Angela and Ninfa lived in the oceans for a very long time. Strong currents pushed plants to the dry land and they quickly died. Some however survived and adapted to the new environment. Thus stated a brand new way of life. 

            The new plants became more and more adapted to dry conditions. They produced flowers and seeds. The strong wind currents moved the seeds to different parts of the planet. For example they went to the desert and rain forests. These seeds found new homes and flourished. In the desert plants became very strong. They developed ways of saving water in their trunks and leaves. There was not much water available. Therefore most plants did not develop branches and did not grow very tall.

Photosynthesis

 

            On the dry surface the primitive plants developed leaves and roots. The roots have two functions: one to hold the plant in place and the other to absorb nutrients and water from the soil. Leaves also help absorb water and light needed to process the nutrients. 

 

            Cactus and Amatillo are two types of plants that adapted to the harsh conditions of the desert. Since the desert only receives less than ten inches of rain a year Cactus and Amatillo store water in their trunks and leaves. The water must last them until next winter. These plants are unique to desert areas but we can also find them in the rain forest. Plants such as Trorafia and Colorbunga are descendants of Cactus and Amatillo respectively.  The plant cells reproduced rapidly. The plant went into a lot of changes. It developed different type of cells. For example, it had to develop epidermis. The epidermis is composed of cells that fit tightly together. The epidermis has two functions to hold the plant together and to protect the inner part of the plant. 

Floor Blanca

            Floor Blanca is a plant that also holds water in its trunk. After winter it produces beautiful white flowers. It does not have many leaves, so that the flowers can be seen from a great distance. Plants share the same genetic structure. The genetic structure is sensitive to heat, cold, dry, and wet environments. Thus, plants vary depending the environmental conditions they live in. For example, leaves growing from submerged stems in the ocean are more finely divided than the leaves growing in the air. The variation occurs even in the  same leaf if it develops half in and half out of water.
