The Man Who Discovered Cells

Robert Hook is known for his natural observation of the 17th century "natural philosopher" - early scientist. But perhaps his most famous discovery occurred in 1665 when he observed the small pieces of cork through the microscope lens and discovered the cells.

Hook was the son of the British Minister and was born in 1635 on the Isle of Wight on the south coast of England. When I was a child, he studied at Westminster School in London. So he studied classics and dynamics. Later he went to Oxford where he served as a Royal Society physician and founding member Thomas Willis' assistant and worked with Robert Boyle, who was known for his gas discovery.

Hook is not as famous as his generation of the same generation. But when he observed microscopic pieces of cork and found that there were some "pores" or "cells", he had a place in his history book. Mr. Hook believes that these cells were containers of 'precious juices' or 'fiber strands' of coniferous trees once alive. Since he and his scientific contemporaries only observed the structure in the plant material, he believes that these cells are found only in plants.

Hook recorded his observations with Micrographia, the first book described with a microscope. The picture on the upper left of flea observed through his microscope was created by Hook. When he was explaining the cork, hook was the first person to use the word "cell" to explain microstructure

Robert Hook found the cell in 1665, and they named them similarly in the monastery where the Christian monks lived. Cell theory was originally developed by Matthias Jakob Schleiden and Theodor Schwann in 1839 and all organisms are composed of one or more cells, which are basic units of the structure and function of all organisms, all cells are It is derived from existing cells. Cells appear on the Earth at least 5 billion years ago. Prokaryotes include bacteria and archaebacteria that are two of these three life domains. Prokaryotic cells are the first living organisms on the planet and are characterized by important biological processes including intracellular signal transduction. They are simpler and smaller than eukaryotic cells and lack membrane-bound organelles like nuclei. Prokaryotic DNA consists of a single chromosome in direct contact with the cytoplasm.

Women produce eggs because some people produce sperm and their germ cells undergo meiosis. Meiosis is initiated within the cell, and each cell has an entire chromosome specific to each organism - human cells have 46 chromosomes. It ends in 4 cells called gametes, each with half of the chromosome. Meiosis is a multistage process in which cells make copies of each strand of DNA called chromosomes and then divide it into two. The amount of DNA is halved each time it is split. In humans, cells are derived from 46 DNA strands and then replicate 96 cells. The first division of meiosis fell from 96 to 46. The second division decreases from 46 to 23. This is the chromosome number of sperm or egg.
