  My topic is about Cell physiology on Wikipedia page. 
  MY goal is that I will improve this topic by adding information and figures if possible.  

    Cell physiology (including cellular electrophysiology) is the biological study which has been a very indispensable study in the last several years which is about the activities that take place in a cell to keep it alive whether the animal cells, plant cells and microorganisms. The term "physiology" refers to all the normal functions that take place in a living organism. all of these activities in the cell could be counted as following ; nutrition, environmental response , cell growth , cell division , reproduction and differentiation. The differences among the animal cell, plant cell and microorganisms shows the essential functional similarity eventhough those cells have different structures. Absorption of water by roots, production of food in the leaves, and growth of shoots towards light are examples of plant physiology.The heterotrophic metabolism of food derived from plants and animals and the use of movement to obtain nutrients (even if the organism itself remains in a relatively stationary position) are characteristic of animal physiology. In the context of human physiology, the term cell physiology often specifically applies to the physiology of membrane transport, neuron transmission, and (less frequently) muscle contraction. In general, these cover the digestion of food, circulation of blood, and contraction of muscles and, therefore, are important aspects of human physiology. For a more complete description of the general physiological function of human cells (as well as the cells of other life forms), see the article on cell biology.

    Experimental approach in cell physiology is an important aspect in cell physiology because it utilizes the experimental methods in order to solve any scientific issue related to physiology. the following examples have been studied in cellular problems by using the experimental method: First, the key of understanding cells' activities in animal, plant cells and microorganisms was studied by identified the nature of organization of cells. Second, the differences of the environment plays a role of the nature of the cell environment, cell resistance and the adjustment. Third, the nature of the cell in regulating and transporting materials into and out the cells crossing the cell membrane. Fourth, Cell foods and its inter-conversions and the mechanism of respiration process to release energy from cell's food. Fifth, the use of energy in respiration in terms of performing the variety types of work. For example, maintenance, readiness, osmotic and for manufacturing of secretions. 

   The relation of cell physiology to different fields of physiology such as, animal physiology, comparative animal physiology, plant physiology and molecular biology are being fundamental parts of physiology field. Animal physiology plays a role of the work of various organs of the body which those organs coordinate to integrate the animal behavior. medical men in were concerned about vertebrate organ physiology precisely with mammals, because the information provided could be beneficially applied to the physiology of human in health and diseases. it is a beneficial to work on organ physiology as an medical approach. However, the Cellular level can be used as well. In addition, Comparative animal physiology is a prat of studying the function of any organ in various types of animals such as, vertebrate and invertebrate to find the fundamental relations. Plant physiology is more likely concerns about the response, nutrition, growth and reproduction of different types of plants. and Since the functioning of the animal and plant depend on the function of the cells component. all of these physiological studies are have recognized by researchers whom were interested in organisms and worked at the cellular level to solve problems at the organs levels. on the other hand, Molecular biology turns to explain the cells activities in at the molecular level.In the past time, it has been limited in studying activities of viruses and bacteria. However, now it is being extended on studying the activities of the Eukaryota cells. Molecular biology has been contributed as an aim for cell physiology by being as powerful source of mutants( this method has been applied to many issues in cell physiology)such as, transportation across the cell membrane and the nature of the membranes. However, many of the cell physiology problems have not been solved by the molecular approach.
