Henri Dutrochet :
*1824
*Dutrochet stated that all organic tissues are actually globular cells of exceeding smallness, united by simple adhesive forces. This helps support the theory that cells are the most basic unit of life.

Franz Meyen :
*1830
*Meyen stated that each cell forms an independent, isolated whole. He also stated that each cell nourishes and builds itself up. This supports the part of cell theory that states that the cell is the most basic unit of life.
