What is Cytology?
'''Cytology''' is the study of the [[cell]]s, especially their appearance and [[structure]]. Cells are the small parts that make up all living things, and their effects on each other and their [[environment]]. There are two types of cells. [[Prokaryote|Prokaryotic]] cells do not have a clear and easy-to-see [[Cell nucleus|nucleus]], and do not have a [[membrane]], or wall, around them. [[Eukaryote|Eukaryotic]] cells have an easy-to-see nucleus where all of the cell's functions take place, and a membrane around them. The main [[organelle]]s of a cell and their uses are: * [[Mitochondria]]: produces [[energy]] for the cell * [[Endoplasmic reticulum]]: makes [[protein]]s and [[carbohydrate]]s for the cell to use * [[Golgi body|Golgi bodies]]: store and package products that the cell uses * Plastid (present in plant cells only): contains chemicals needed to [[photosynthesis|photosynthesize]] (create energy from sunlight); in plants only. * [[Nucleus]]: directs the actions of the cell * [[Centrosome]]s: guides the cell in [[mitosis]] and [[meiosis]], the processes for cell division. ==Related pages== *[[Cell biology]] is mostly about how cells work, and about [[cell division]] and [[molecular biology]]. *[[Histology]] deals with techniques for looking at tissues under a [[microscope]]. *Cytopathology is a medical discipline that deals with techniques for looking at cells under a [[microscope]]. {{biology-stub}} [[Category:Cell biology| ]] [[Category:Molecular biology]]
