The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Schleiden suggested that all the different parts of plants are made of cells. LUCA was one of the earliest prokaryotic cells. These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within cells. Cell Theory is one of the basic principles of biology. Who are the 10 scientists who discovered cells?

They recognized the common features of cells to be the membrane, nucleus, and cell body and described them in comparisons of various animal and plant tissues. Rudolf Virchow later made important contributions to this theory. Despite the limitations of his now-ancient lenses, van Leeuwenhoek observed the movements of protista (a type of single-celled organism) and sperm, which he collectively termed animalcules.

By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. Schleiden further suggested that cells were made by a crystallization process either within other cells or from the outside.

Before him, many people believed in spontaneous generation, or the idea that life can literally occur without any other living source of life.
