while robert hooke’s discovery of cells in 1665 led to the proposal of the cell theory, hooke misled the cell membrane theory that all cells contained a hard cell wall since only plant cells could be observed at the time. microscopists focused on the cell wall for well over 150 years until advances in microscopy were made. in the early 19th century, cells were recognized as being separate entities, unconnected, and bound by individual cell walls after it was found that plant cells could be separated. this theory extended to include animal cells to suggest a universal mechanism for cell protection and development. by the second half of the 19th century, microscopy was still not advanced enough to make a distinction between cell membranes and cell walls. however, some microscopists correctly identified at this time that while invisible, it could be inferred that cell membranes existed in animal cells due to intracellular movement of components internally but not externally and that membranes weren’t the equivalent of a cell wall to plant cell. it was also inferred that cell membranes weren’t vital components to all cells. many refuted the existence of a cell membrane still towards the end of the 19th century. in 1890, an update to the cell theory stated that cell membranes existed, but were merely secondary structures. it wasn’t until later studies with osmosis and permeability that cell membranes gained more recognition. in 1895, ernest overton proposed that cell membranes were made of lipids.
