<P> The cell was first discovered by Robert Hooke in 1665 , which can be found to be described in his book Micrographia . In this book , he gave 60 ' observations ' in detail of various objects under a coarse , compound microscope . One observation was from very thin slices of bottle cork . Hooke discovered a multitude of tiny pores that he named `` cells '' . This came from the Latin word Cella , meaning ' a small room ' like monks lived in and also Cellulae , which meant the six sided cell of a honeycomb . However , Hooke did not know their real structure or function . What Hooke had thought were cells , were actually empty cell walls of plant tissues . With microscopes during this time having a low magnification , Hooke was unable to see that there were other internal components to the cells he was observing . Therefore , he did not think the `` cellulae '' were alive . His cell observations gave no indication of the nucleus and other organelles found in most living cells . In Micrographia , Hooke also observed mould , bluish in color , found on leather . After studying it under his microscope , he was unable to observe `` seeds '' that would have indicated how the mould was multiplying in quantity . This led to Hooke suggesting that spontaneous generation , from either natural or artificial heat , was the cause . Since this was an old Aristotelian theory still accepted at the time , others did not reject it and was not disproved until Leeuwenhoek later discovers generation is achieved otherwise . </P>
