- Shwann discovered that all animals are made of cells! Did you know that cells come from preexisting cells?
- No! I didn't. Thanks for telling us.
- My studies of the notochord led me to propose that the nucleated entities I had observed were the animal counterparts of the plant cells
- Schleiden declared that the cell is the basic building block of all plant matter. Cells are organisms and all organisms consist of one or more cells.
- all plant tissues are composed of cells and that an embryonic plant arose from a single cell.
