Rudolf Virchow: Father of Modern Pathology. Cells were discovered in the middle of the seventeenth century after the microscope was invented. Before that time, the individual organism was studied as a whole in a field known as organismic biology; that area of research remains an important component of the biological sciences. They share many common features, such as a cell membrane, nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, ribosomes, and more.. A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.White blood cells carry out their defense activities by ingesting foreign materials and cellular debris, by destroying infectious agents and cancer cells, or by producing antibodies. Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Biology Expert.
