What is cell biology in short answer?
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms.

Biology. a usually microscopic structure containing nuclear and cytoplasmic material enclosed by a semipermeable membrane and, in plants, a cell wall; the basic structural unit of all organisms.
What is a simple cell easy definition?
A simple cell in the primary visual cortex is a cell that responds primarily to oriented edges and gratings (bars of particular orientations). These cells were discovered by Torsten Wiesel and David Hubel in the late 1950s.
What is in a cell biology?
Cell biology can be divided into many subtopics, including the study of cell metabolism, cell communication, cell cycle, and cell composition. Research in cell biology is interconnected to other fields such as genetics, biochemistry, neurobiology, plant biology, molecular biology, microbiology, and immunology.

What is the definition of a cell and its type?
A biological cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialized to perform a particular function in multicellular organisms (e.g. plants and …
