Matthias Jakob Schleiden and Theodor Schwann proposed that all living things are made of cells, one of the main points stated in the cell theory. This was modified by Rudolf Virchow.
In 1838 by Matthias Schleiden and by Theodor Schwannproposed this theory.
The cell theory states:Cells are the basic units of structure and function in living things.All living things are composed of cells.All cells are produced from other cells.
Scientists first thought of them as small animals. They first observed cells using the microscope and the work of many scientists led to the development of the cell theory.
Robert Hooke discovered cell theory and cells
Cell theory is one of many subdivisions of scientific theory. Therefore, since cell theory IS scientific theory, I don't see how you can compare them. This is like saying compare mammals to squirrels.
It means that cells form the fundamental units of all living organisms. It was proposed by Matthias Schleiden and Theodor Schwann.

Organic systems and cells
The word "theory" is used differently by scientists than by the general public. The general public means "theory" as a proposed explanation for something which is not proven and which is possibly spurious; scientists may mean "theory" in that way, but may also mean "theory" as a hypothesis that has been tested multiple times and has been validated each time. Also leukocytes which mean white blood cells.
In 1838 by Matthias Schleiden and by Theodor Schwannproposed this theory.
More scientists worked on finding out about cells
Matthias Schleiden studied plant tissues and made the first statement of cell theory. He stated that all plants are aggregates of individual cells which are fully independent. Theodor Schwann reported that all animal tissues are also composed of individual cells. Rudolf Virchow proposed an important extension of cell theory that all living cells arise from the pre existing cells.
The cell theory states:Cells are the basic units of structure and function in living things.All living things are composed of cells.All cells are produced from other cells.
Matthias Schleiden, Theodor Schwan, and Rudolph Virchow all stated that cells must come from existing cells. This is known as the cell theory.
