All cells spring from other cells through and through cell division. In multicellular organisms, every cell in the organisms body derives ultimately from a unity cell in a fertilized egg. The cell is also consi! dered to be the basic unit in many pathological processes.[12] Additionally, the phenomenon of energy flow occurs in cells in processes that are part of the function known as metabolism. Finally, cells contain hereditary information (DNA) which is passed from cell to cell during cell division. ssociate with their environment.[3]If you want to get a beat essay, order it on our website: OrderEssay.net
