Later advances in lenses, microscope construction, and staining techniques enabled other scientists to see some components inside cells. Originally trained as a lawyer, he was really more interested in botany. He has since founded his own financial advice firm, Newton Analytical. Cell theory has become the foundation of biology and is the most widely accepted explanation of the function of cells.

Many sciences come down to the study of very basic concepts. English physicistRobert Hooke, who describedcorkand otherplanttissues in 1665, introduced the termcellbecause thecellulosewalls of dead cork cells reminded him of the blocks of cells occupied bymonks. Schleidens contributions on plants were acknowledged by Schwann as the basis for his comparison of animal and plant structure. Cells arise from other cells through cellular division. 6 What are the three scientists contributed to the cell theory? Schleiden suggested that all the different parts of plants are made of cells. 1674 - Leeuwenhoek discovered protozoa. Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. The inspired Dutch microscopistAntonie van Leeuwenhoek, beginning in 1673, discoveredblood cells,spermatozoa, and a lively world of animalcules. A new world of unicellular organisms was opened up. Even after the publication in 1672 of excellent pictures of plant tissues, no significance was attached to the contents within the cell walls. FIRST PART. The first part states that all organisms are made of cells. The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).Since the formation of classical cell theory, technology has improved, allowing for more detailed observations that have led to new discoveries about cells. The two scientists wrote each other about these discoveries to conclude that the cell is the basic unit of life.The collaboration between Schwan and Schleiden firmly established the second part of . | 26 A statement by Schleiden pointed toward the future direction of cell studies: Each cell leads a double life: an independent one, pertaining to its own development alone; and another incidental, insofar as it has become anintegralpart of a plant. Called the electron microscope, it used a beam of electrons instead of light to observe extremely small objects. Cell theory proposed certain concepts .
