CELL THEORY
THE OLD STATEMENTS OF THEORY
Cell come from preexisting cells
All living organisms are maded by cells
They are the basic unit of live
EUKARYOTES
Most Important Organells
Nucleus: It contains all the genetic code
Vacuole: help sequester waste productes
Mitocondria: generate of the energy needed to power the cells
prokaryotes
arche
bacterias
THE NEW STATEMENTS OF CELL THEORY
Each cell is a unique and unrepeatable open system, which exchanges matter and energy with its environment. All vital functions fit in a cell, so that a cell is enough to have a living being (which will be a unicellular living being). Thus, the cell is the physiological unit of life).
HISTORY
Cell theory is the most important and relevant part of biology that explains the constitution of living matter based on cells and the role that these cells play in the constitution of living matter. In 1665, the English scientist Robert Hooke, examining a cork slide under the microscope, noticed that it was formed by small polyhedral cavities which he called cells, meaning "little cells".
However, it was not until good optical microscopes became available, at the beginning of the 19th century, that it was found that all living organisms, both animal and vegetable, are composed of cells. According to the cellular theory, we have the possibility of concluding that: the cell is the structural and serviceable unit of living organisms, so that the essential activity of these is the result of the sum of the occupations of each of its cells, in the midst of which there is a coordination.
