Transcript of The Cell Theory

Cell Theory
Types of Microscopes
Compound: light illuminated, 2-D image, high magnification, low resolution. Most used. (Miamioh, n.d.).
Matthias Schleiden
All living organisms consist of one or more cells.
Theodor Shwann
Discover plants are made of cells.
Discover animals are made of cells.
Stereoscope:light illuminated,3-D image, low magnification. Used for dissection. (Miamioh, n.d.).
(GEEK, n.d.)
(GEEK, n.d.)
Confocal: uses laser light because of the wavelength, and it pass to a digital computer screen. (Miamioh, n.d.)
Electron micorscope (TEM): electron illuminated, 2-D image, high magnification and resolution. (Miamioh, n.d.).
(OLYMPUS, 2004)
(Swapp, n.d.)
Scanning Electron Microscope: electron illumination,3-D image, high magnification and resolution, black and white pictures. (Miamioh, n.d.).
(Swapp, n.d.)
1. The activity of an organism is dependent on both the individual and collaborative activities of its cells (Rajalakshmi, 2009).
2. The cell is the basic structural and functional unit of living organisms (Rajalakshmi, 2009).
3. All cells arise from preexisting cells (Rajalakshmi, 2009).
4. The biochemical activities of cells are determined and made possible by the sub-cellular structures of the cell.
Important Scientists
Concerning the Cell Theory
Hans and Zacharian Janssen
(Clip Art, 2009)
(HDW, 2009)
(Wallpaper, 2014)
He produced the first compound microscope in 1595.

Swapp, S. (n.d.). Geochemical. Retrieved from

He discovered the cellular composition of the cork in 1665 and invented the term "cell".
Anton van Leeuwenhoek
From the types of microscopes and the cell theory and the scientist that discover it.
Importance of the microscopes
Made magnification improved by polishing the lenses in 1674.
He also discovered "animalcules" (cells) in 1676.
(Cells Webquest)
(The Lint Screen, 2011)
All of the microscopes are really important for the cell theory and for science because the first microscope was the tool that scientist use to discover the cells. With them they see all of the microorganisms that cannot be seen at simple eye. Nowadays we have many different microscopes and with each one of them you can see different things about microorganisms.
(Sponge Lab A Global Science Community, 2013)
Matthias Schleiden
(Grace's Blog, 2014)
Discovered plants were made of cells in 1838.
Theodor Schwann
Discovered animals were made out of cells 1839.
Rudolph Virchow
He stated that all living things come from other living things in 1855.
