What Does cell theory Mean
The concept of theory can make mention of a hypothesis whose result can be applied to a science; the group of laws that serve to establish links between events or phenomena; or knowing that it has not yet been verified.
Cell , for its part, is that related to cells : the minimal and primordial unit that constitutes living beings.
Before proceeding with the notion of cell theory , we must know that this idea is part of the so-called scientific theories , formed by concepts that, following certain rules, allow to detail the relationships between observations made of the concepts in question. In other words: a scientific theory is built from the empirical data obtained through observations.
The cell theory , in this sense, is used in the field of biology to provide an explanation of the constitution of living organisms from cells . This theory details how cells are essential for the existence of life and how they determine the most important characteristics of living beings.
According to cell theory, living matter can metabolize and perpetuate itself, unlike matter that lacks life. Cells are the fundamental units that make up the structure of this living matter: organic functions develop inside cells or in their closest environment, under the control of the substances they secrete. The cell theory also indicates that cells come from other pre-existing cells through their division .
In addition to the data presented so far on the cell theory, it is worth knowing other equally relevant and significant ones such as these:
-The first study or investigation that began to lay the foundations of the aforementioned cell theory was carried out in 1665 by the British scientist Robert Hooke, who is considered the father of cells, their discoverer. And it is that this, by examining a cork sheet with the microscope, was able to verify that said object was formed by different cavities that he called cells, cells. A study that was followed by others who came further to delve into its discovery, such as the one undertaken by Antony van Leeuwenhoek, also in the seventeenth century.
-The cell theory as such, however, it is established that it was developed from the principles established by Schleiden and Theodor Schwann in the years 1838 and 1839.
-Another key moment in the history of cell theory was the establishment in 1858 of Virchow's idea: "every cell comes from another cell."
-The scientists who managed to demonstrate and develop it with the greatest skill throughout history and after the aforementioned discoveries were Pasteur, who specialized in the multiplication of unicellular microorganisms; Santiago Ramón y Cajal, who shaped the neuron doctrine, and Camillo Golgi, who had the merit of identifying one of the well-known nerve cells. Two figures, these last two, who precisely for these discoveries managed to be recognized with the Nobel Prize in 1906.
