Histology
Histology is the study of the cells and tissues of animals, plants and humans. The cells and tissues are placed under a microscope and study is conducted in order to determine the diseases and other abnormalities. This science is built on the grounds of high discipline as it studies the building blocks of plants, animals and human structure. The tissues or the collection of cells are studied in groups. For instance, in plants, cell histology examines how the cells process the absorbed nutrients and get rid of waste and communicate with other cells. On the other hand, human histology focus on how cells become tissues which them form organs in the body system.
