Definition of Cell Biology

Cell biology in a science that is responsible for studying the properties, functions, structures, components of cells, as well as the interaction they have with the environment and the life cycle. With the appearance of the microscope it became easier to study the cells, making possible the study of certain structures that had never been studied by humans, using cytochemical techniques and coloring of the samples to be studied.

Those skilled in the art are responsible for studying cells from a molecular point of view, this is what is known as molecular biology. Some of the structures most frequently studied in cellular biology are mitochondria, ribosomes, the membrane and the endoplasmic reticulum. The use of this science in daily life can be seen in the study of certain diseases, allowing them to know how they work and then fight them properly, through the creation of treatments to eliminate bacteria and viruses, besides contributing in the repair of some tissues of the body.

The scientist Robert Hooke was one of the first to use the term cell, referring to certain hollow polyhedral shapes that made up structures of some plant origin, but it was not until the 19th century that the concept evolved taking into account the structure internal In this same century is when the so-called cell theory develops, which admits the cell as the structural and functional basis of living organisms, becoming the fundamental element of biology today. Thanks to this theory, research in the field of biology began to concentrate more towards the field of microscopy since the structures were not seen by the human eye.

Investigations in the field of microscopy, were not slow to give results, resulting in the discovery of the internal structure that makes up the cell (chromosomes, nucleus, cytoplasm, Golgi etc.) and the relationship between these elements. In the 20th century with the advent of electronic microscopy, discoveries of ultracellular structures were possible, giving way to the creation of histochemistry, cytochemistry and cytogenetics.
