International is a scientific organization that promotes open access for relevant scientific information and research findings. About 700+ peer-reviewed journals are handled by more than 25000 editorial board members who belong to both academic and industrial circles in all aspects of Science, Engineering, Management and Technology journals. A collaboration set up recently with 100 international societies would provide a window to wider knowledge-base of worldwide open access health-related information. Cells are the basic structural and functional and unit of all known living organisms and are referred to as "building blocks of life". Organisms can be classified as unicellular and multicellular on the basis of number of cells. Organisms having single cell are called as Unicellular and those with multiple number of cells are called as multicellular organisms. In 1665 Robert Hooke discovered the cell. Matthias Jakob Schleiden and Schwann, were the first to explain the cell theory in 1839 which states that all organisms are composed of one or more cells, and all cells emerge from pre existing cells, vital functions of an organism occur within cells and all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation.
