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".
Since the invention of the microscope in the seventeenth century it has been known that plant and animal tissue is composed of cells : the cell was discovered by Robert Hooke. The plant cell wall was easily visible even with these early microscopes but no similar barrier was visible on animal cells, though it stood to reason that one must exist.

Cells were discovered by Robert Hooke in 1665, who named them after their resemblance to cells inhabited by Christian monks in a monastery. Cell theory , developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann , states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function ...
Robert Hooke's discovery of cells in 1665 led to the proposal of the cell theory. Initially it was believed that all cells contained a hard cell wall since only plant cells could be observed at the time. [9] Microscopists focused on the cell wall for well over 150 years until advances in microscopy were made.
Hooke most famously describes a fly's eye and a plant cell (where he coined that term because plant cells, which are walled, reminded him of the cells in a honeycomb [2]). Known for its spectacular copperplate of the miniature world, particularly its fold-out plates of insects, the text itself reinforces the tremendous power of the new microscope.
The fact that PLK-1 endures in the cells of tumors shows that it endures in general, and is involved in mitosis (the division of cells for replication) under even extreme body conditions like ...
Robert Remak (26 July 1815 – 29 August 1865) was an embryologist, physiologist and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. [1] as well as several other key discoveries.
