They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. </span>
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.<span> </span>
