What is the composition of cytoplasm? also summarize the key points of the cell theory.

In 1838, a German botanist Matthias Schleiden concluded that all plants are composed of cells. A year later, Theodor Schwann, a German zoologist concluded the same thing from animals. All animals are composed of cells. In 1821-1902 Rudolf Virchow, German physicians said in his study of human diseases that all cells come from other cells. These three observations were combined to form a basic theory about the cellular nature of life

All organisms are composed of one or more cells 
Cells are the basic unit of structure and function in a living organism
Cells come only from the reproduction of existing cells
