Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
A chromosomal deletion that is too short to cause any apparent change in morphology under a light microscope, though it may still be detectable with other methods such as sequencing. microfilament A long, thin, flexible, rod-like structure composed of polymeric strands of proteins, usually actins , that occurs in abundance in the cytoplasm of ...
The flow of cytoplasmic components plays an important role in many cellular functions which are dependent on the permeability of the cytoplasm. [8] An example of such function is cell signalling, a process which is dependent on the manner in which signaling molecules are allowed to diffuse across the cell. [9]
Neuropharmacology – study of how drugs affect cellular function in the nervous system. Neurophysiology – study of the function (as opposed to structure) of the nervous system. Systems neuroscience – studies the function of neural circuits and systems. Theoretical Biology – the mathematical modeling of biological phenomena.
Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope. Cells emerged on Earth about 4 billion years ago.

This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
This is a clinical laboratory finding. It is visualized by drawing blood from a patient and viewing the blood smeared on a slide under a microscope. Normal neutrophils are uniform in size, with an apparent diameter of about 13 μm in a film. When stained, neutrophils have a segmented nucleus and pink/orange cytoplasm under light microscope.
