Nageli and Cramer in 1855 had already suggested that biological cells are separated from their environment by a membrane possessing special characteristics, and in 1900 Overton performed some simple but classical experiments which proposed that cell membranes were composed of lipids (1).
Below are some names and descriptions of organelles commonly found in cells. There is also an interactive cell viewer and game that can be used to learn about the parts of animal and plant cells. Plasma membrane- The membrane enclosing a cell is made up of two lipid layers called a bilipid membrane. The lipids that are present in the plasma membrane are called phospholipids.. These lipid layers are made up of a number of fatty acid building blocks.
