What did Schleiden and Schwann contribute to the cell theory?
In 1838 Schleiden defined the cell as the basic unit of plant structure , and a year later Schwann defined the cell as the basic unit of animal structure. Schleiden and Schwann articulated their observations as a unified theory—the cell theory—in 1839.
Who named the cell?
The Origins Of The Word ‘Cell’ In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork.
