Material and Energy transport in organisms

Every multicellular organisms would require water and nutrients from the environment and the metabolic waste released into the environment. Water and nutrients required can not be obtained directly by all the organs. Therefore there is need for systems that carry the substance of the organ to the absorption of organs that need. In plant cell protoplasm has a plasma, whereas in animal cells are the cell plasma membrane of cells. Plasma cells or cell membranes have the ability to regulate the flow of fluid from the environment of a good cell into the cell or out of cells selectively. There are two fisiokimia process of diffusion and osmosis (Kimball, 1992).

Transport in plants is very important is photosynthesis. Fotositesis activity is the process of formation or kmia energy by forming organic compounds and are anorgank by Using the sun, where no ray will not happen matahar photosynthesis process. As for understanding the evolution of photosynthesis is light driven, water and energy storage resulting reduction in the various other components that make up the carbon micro-organism (Wilkina, 1992).

       Osmosis is the movement of water from the solution molekol a high water concentration to a low concentrated solution through a membrane smipermiable or selectively permeable (Syamsuri, 2000).

        Plasmolysis is the process of separation of protoplasm from the cell wall caused by water seeping in from vakoula el, and to return the opposite process is required, namely deplasmolisis (Kimball, 1992).

        Red blood cells must be in a state that sotonik, if not going to happen that isebut Crenation pengkerutan, whereas when in the solution will experience swelling hipertonk. Then broke out and resulted in red hemoglobin, this event is called hemolysis (Wilkina, 2000).

Cell protoplasm in plants and has a plasma membrane of animal cells capable of selectively regulate the flow of cells from the fluid environment of a cell into the cell or vice versa. There are two important processes fisiokimia, namely diffusion and osmosis, with the process stated osmoses of a permeable membrane, semipermiable, or impermiable. Transport systems in plants involves a process dfusi, osmosis, and active transport (Saktiyono, 2000).

        Plants take food and water in the form of mineral salts dissolved in it and the O2 and CO2 from the environment. Capture and transport of food going through the process of diffusion, osmosis, and Active transport. Substances and the dangers of chemical water through the roots, while the gases O2 and CO2 through the leaves. Substance that is needed and the rest of giant metabolism need to be transported. Transportation system is very pentig for plants and animals associated with the mass of the organism. Transportation is happening in the body of animals and plants occur in active or passive (D. Dwidjoseputro, 1986).

        Molecules of water as a solvent slightly, while the large solute molecules. Thus, when viewed from the osmotic solution hipertonis, in fact also review the water molecules in the solution (Saktiyono, 2000).

        Diffusion is a physical event which is very useful for plant life. Diffusion occurs because of relief of concentration, which diusi pressure menmbulkan, then with dmikian ifusi can dideinisikan as movement of liquid molecules from high concentration solution to a solution of low concentration yag (Kimball, 1992).

          Active transport is the transport of substances through the barriers in a way that a membrane is impermiable which allegedly plasmalenia to use energy from ATP (Kimball, 1992).

         Imbibisi the event of water absorption by the surface is hydrophilic substances, so-zt substances such as proteins, starches, gelatin, gelatin can expand the After absorbing water (Kimball, 1992).
