Biological Oxygen Transport Essay Example | Topics and Well Written Essays - 1500 words

Biological atomic number 8 convey - Essay ExampleThe term biological group O expect refers to the incorporation of oxygen from the environment into the cellphone. It covers wholly the processes right from breathing to the respiration. Such transport process encompasses different levels of harmoniumization from organism to the level of submarine cellular organelles. The transport of oxygen in various biological sy husks majorly depends upon the process of diffusion and convection.Generally in that location atomic number 18 two biological systems plant and animals. Plants do not have any specialized organ for the transport of oxygen. Roots stem and leaves are major sites involved in uptake and release of oxygen. Oxygen is absorbed for respiration and is released into the atmosphere as a result of photosynthesis. Leaves being exposed to air are the major sites of oxygen uptake. Air mixed oxygen enters the empty spaces in the leaves through the openings called stomata. The entr y of oxygen to the intracellular air spaces is followed by the process of rapid diffusion. The interior of the cells have less oxygen submersion as compare to the exterior. So, following the principle of diffusion, oxygen moves from the higher exterior absorption to the lower concentration inside the cell. This transport is accomplished by passing through various cellular-barriers such as cell wall and cell membrane. Oxygen being non polar easily diffuses through these barriers.Oxygen can overly be transported through the stem and the roots. The cork of roots and stem contain openings called lenticels, for the transport of oxygen into and forbidden of the plant body. Moreover plants with soft green stems bear stomata for the transport of oxygen.As far as the transport of oxygen within the plants is concerned, experiments have shown that the plant contains non tortuous gas filled channels between the stem and the root. Apart from the lenticels the oxygen requirement
