<unk>  (also<unk> ular biology or cytology) is a branch of biology that studies the structure, function and behavior of<unk> s. All living organisms are made of<unk> s. A<unk>  is the basic unit of life that is responsible for the living and functioning of organisms.<unk>  is the study of structural and functional units of<unk> s.<unk>  encompasses both prokaryotic and eukaryotic<unk> s and has many subtopics which may include the study of<unk>  metabolism,<unk>  communication,<unk>  cycle, biochemistry, and<unk>  composition. The study of<unk> s is performed using several microscopy techniques,<unk>  culture, and<unk>  fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how<unk> s function, ultimately giving insight into understanding larger organisms. Knowing the components of<unk> s and how<unk> s work is fundamental to all biological sciences while also being essential for research in biomedical fields such as cancer, and other diseases. Research in<unk>  is interconnected to other fields such as genetics, molecular genetics, molecular biology, medical microbiology, immunology, and cytochemistry.
