Question

what is cell theory ?state the three key point of the cell theory​

Answer 1

Answer:-

Credit for developing cell theory is usually given to two scientists: Theodor Schwann and Matthias Jakob Schleiden.While Rudolf Virchow contributed to the theory, he is not as credited for his attributions toward it. In 1839, Schleiden suggested that every structural part of a plant was made up of cells or the result of cells. He also suggested that cells were made by a crystallization process either within other cells or from the outside. However, this was not an original idea of Schleiden. He claimed this theory as his own, though Barthelemy Dumortier had stated it years before him. This crystallization process is no longer accepted with modern cell theory. In 1839, Theodor Schwann states that along with plants, animals are composed of cells or the product of cells in their structures. This was a major advancement in the field of biology since little was known about animal structure up to this point compared to plants. From these conclusions about plants and animals, two of the three tenets of cell theory were postulated.

All living organisms are composed of one or more cells.

1. The cell is the basic unit of structure and organization in organisms.
2. Cells arise from pre-existing cells.
3. There is no universally
