Cell Theory

Cell Theory
Cell theory refers to the idea that cells are the basic unit of structure in every living thing. This theory is one of the foundations of biology. The theory says that new cells areformed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all living stuff .
The cell was discovered by Robert Hooke in 1665. He examined (undera coarse, compound microscope) very thin slices of cork and saw a multitude of tiny pores that he remarked looked like the walled compartments a monk would live in. Because of this association,Robert Hooke called them cells, the name they still bear.
In 1824, Rene Dutrochet discovered that "the cell is the fundamental element in the structure of living bodies, forming both animals and plantsthrough juxtaposition." However, the first sightings of the internal action of the cell were made by Robert Brown. In Berlin, Johannes Muller created connections between biology and medicine, promptingthe connective thinking of his students, such as those of Theodore Schwann. Schwann created the term "cell theory" and declared that plants consisted of cells. This declaration was made after that ofMatthias Schlieden's (1804 - 1881) that animals are composed of cells.
The cell theory holds true for all living things, no matter how big or small, or how simple or complex. Since according toresearch, cells are common to all living things, they can provide information about all life. And because all cells come from other cells, scientists can study cells to learn about growth, reproduction,and all other functions that living things perform. By learning about cells and how they function, you can learn about all types of living things.
Credit for developing cell theory is usually given tothree scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow.
The generally accepted parts of modern cell theory include:
