Document Summary
The cell theory - was developed during the mid 1600s because of the discovery of microscopy. All cells only come from other cells (the principle of biogenesis) and 2. Cells are the fundamental units of organisms: robert hooke applied the microscope science, antony van leeuwenhoek (who was living in amsterdam) greatly enhanced and developed the microscope. There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell"s genetic material, while prokaryotic cells don"t have a nucleus and have free-floating genetic material instead. Comprised of: the cell surface, plasma membrane, cytoplasm, mitochondria, endoplasmic reticulum (er, vesicles, the nucleus, eukaryotic cells are distinguished from prokaryotic cells by the presence of membrane enclosed organelles within their cytoplasm. These organelles provide discrete compartments in which specific cellular activities take place. Transmembrane proteins - transport proteins: cell to cell recognition.
