Who discovered the cell for the first time, and how did

Robert Hooke. He discovered the cell in 1665 by examining a thin slice of cork and seeing a multitude of little pore. He said thet the pores looked like the walled compartments a monk would live in, because of this he called them cells the name they still have today. Even though Hooke discovered the cell he did not know of the structure. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope In 1665, Robert Hooke was the first person to discover cells. When Hooke viewed a thin cutting of cork with his microscope he discovered empty spaces contained by walls, and termed them pores, or cells. The term cells stuck and Hooke gained credit for discovering the building blocks of all life The next significant discovery occurred in 1833 when the British botanist Robert Brown first discovered the nucleus in plant cells. From the years 1838-1839, the German scientist Matthias Schleiden proposed the first foundational belief about cells, that all plant tissues are composed of cells In the first decade of the eighteenth century, nucleus was probably observed in plant and animal tissues, but the first description of nuclei in epithelial cells was made by Felice Fontana (1730-1805) and published in 1781 in the Traitésur le Vénin de la Vipére [ 3, 37 ]

The First Cells It was once believed that the formation of the first cell was the most difficult and time consuming part of creation, but once that first cell had formed, it had not taken long for multicellular organisms to evolve.. Fossil evidence shows that multicellular life came into existence about 600 million years ago, however, the age of the earth was over 4.6 billion years old There are three parts to this theory. The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells
