Aside from Lamarck's contributions to evolutionary theory, his works on invertebrates represent a great advance over existing classifications; he was the first to separate the Crustacea, and Annelida from the "Insecta." His classification of the mollusks was far in advance of anything proposed previously; Lamarck broke with tradition in removing the tunicates and the barnacles from the . He also anticipated the work of Schleiden & Schwann in cell theory in stating that: . . . no body can have life if its constituent parts are not cellular tissue or are not formed by cellular tissue."
He dissected animals and studied the ways that they reproduce.
1838, he discovered that all animals are made up of cells!
All life actives take place in cells #one answer
von Mohl developed the idea that the nucleus of the cell was within the granular, colloidal material that made up the main substance of the cell. In 1846 he named this substance protoplasm
He studied plant structure under a microscope, and saw the intner cell parts. He found that the cell nucleus was very important, and thought that it might be connected with cell division. He concluded that all plant parts were made of cells, contributing to the cell theory.
The name of the theory that Schleiden and Schwann developed is the cell theory.
Lamarck proposed an hypothesis that had species evolving desired traits and passing them to their offspring. For example, if you were a bodybuilder, your offspring would be born with larger than normal muscles. This hypothesis, while incorrect, was still significant in the history of evolutionary thought.
He said that cells can reproduce cell

she didn't
he stated that the cell is a structural unit of an organism.
