What is Cell Biology? Cell biology is the study of cell structure & function ORGANIZATION OF THE HUMAN BODY 1-CELL: smallest structural & functional unit. 2-TISSUE: cells having same characters: – Epithelial. – Connective. – Muscular. – Nervous. 3-ORGAN: tissues together perform special function. 4-SYSTEMS: organs together perform complex function. Cytology Cytology is the science which deals with the study of cells. What is cell membrane? = Plasma membrane = plasmalemma
