MARCELO MALPIGHI (1620-1694)
- Considered to be the father of the microscopy
- He made obrervations of tissues
- Malpighi made many drawings of his observationsANTON VAN LEEUWENHOEK (1632-1723)
- He manufactured some microscopes and
then used them to observe microorganismsROBERT HOOKE (1635-1703)
- He studied a sheet of cork with a simple microscope
- Hooke named the cells
- cell = small room (latin)ROBERT BROWN (1773-1857)
- He observed the plant cells
- He discovered the nucleus in plant cells
- Later scientists that the structure is in all eukaryotic cellsMATTHIAS SCHLEIDEN (1804-1881)
-Came to the conclusion that all plants are made of cellsTHEODOR SCHWANN (1810-1882)
- A year later concluded that all animals are also made of cells like
Schleiden concluded for plants.RUDOLF VIRCHOW (1821-1902)
- Studied the physiology of cells
- Concluded that every cell carried out the three vital functions
- His work led to the completion
of the other two principles of the cell theory- Based on the conclusions of both scientist the first principle of the cell theory was developedSANTIAGO RAMÓN Y CAJAL (1852-1934)
- He proved that the cell theory also applied to nervous tissue
- Cajal studied tissue samples obtained from embryos and infants
- He observed that the tissues are made up of cells
- He was awarded the Nobel PrizeMICROSCOPES
- Optical microscopes were greatly improved
- Microscopes continue to evolve today.
- Now we are able to observe tiny details inside cells and organelles
