- The word cell was first used by English scientist Robert Hooke in 1665 to describe the cell walls visible in cork when seen through a microscope. In 1838 the German botanist M…atthias Schleiden concluded that all plant tissues were made of cells. In 1839 the zoologist Theodor Schwann reached the same conclusion about animal tissues. By 1885 the German physiologist concluded that cells only originated by the division of a preexisting cell.

History of Biology: Cell Theory and Cell Structure Early Observations. The invention of the microscope allowed the first view of cells. English physicist and microscopist Robert Hooke (1635–1702) first described cells in 1665. He made thin slices of cork and likened the boxy partitions he observed to the cells (small rooms) in a monastery.he first unequivocal description of the cell nucleus was made by a Czech, Franz Bauer, in 1802 and was given its name in 1831 by Robert Brown (1773–1858) of Scotland, who is best remembered for discovering the random Brownian motion of molecules.

Antony van Leeuwenhoek (1632-1723) Leeuwenhoek looked at animal and plant tissues, at mineral crystals and at fossils. He was the first to see microscopic foraminifera, which he described as little cockles. . . no bigger than a coarse sand-grain.. He discovered blood cells, and was the first to see living sperm cells of animals.

Robert Hooke (28 July 1635 â 3 March 1703) It was in his description of cork that he first used the term cell even though he did not know how important his discovery would become. The cell wasn't really understood until 1839 when scientists began to discover its importance.

"Why did Robert Hooke use the term ""cells"" in reference to small biological organisms?" What did Gustav Kirchhoff and Robert Hooke both discover? In 1665, Hooke, an English natural philosopher, published Micrographia, the first book to contain illustrations of the microscopic world. In the book, Hooke used the term cell to describe the microscopic structure of a thinly sliced piece of cork.

- Hooke's Microscope Hooke's drawing of Cork Cells. 1670: Antonie van Leeuwenhoek (1632-1723) described cells in a drop of pond water using a microscope. A Dutch businessman and a contemporary of Hooke. He also used microscopes and was a physicist. He made his own fine quality lens for use in monocular microscopes and was the first person to observe bacteria and protozoa. Some of his lenses could magnify objects 250X.

- Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells.

Cell theory 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.

History of Cell Biology Hooke’s description of these cells was published in Micrographia. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.

What Were Theodor Schwann's Contributions to Cell Theory? Although there was some minor advancement in cellular theory between Hooke's discoveries and the presentation of Schwann's and Schleiden's theory, it was Theodor Schwann that first introduced the idea that living things are composed of cells.

- DISCOVERY OF CELLS The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke. Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery.

Evolution of cells The first cells [edit]. The origin of cells was the most important step in the evolution of life on Earth. The birth of the cell marked the passage from pre-biotic chemistry to partitioned units resembling modern cells.hese would foster subsequent cellular evolution and metabolism. Each of these three essential processes probably originated and was lost many times prior to The First Cell, but only when these three occurred together was life jump-started and Darwinian evolution of organisms began.

Hooke drew the cells he saw and also coined the word CELL.lso, when Robert Hooke discovered cells, he was not a criminal and he also did not get tours of jail. He did not know what jail cells looked like. Though, he did know what semenary rooms for priests looked like, as he was very religious.

When did scientists realize that all organisms contain cells? 1839 Although first seen by Robert Hooke in 1695 (he also first used the term cells), it wasn't until 1839 when Theodor Schwann and Mattais Schleiden first theorized that all plants and animals are made of cells in The Theory of Cells.

Explore the BBC Exactly when the first life on Earth-the ancestors of modern bacteria-began is a subject of debate, but evidence suggests it could be as much as 3.5 billion years ago. Early bacterial life introduced oxygen to the atmosphere. As the first free oxygen was released through photosynthesis by cyanobacteria, it was initially soaked up by iron dissolved in the oceans and formed red coloured iron oxide, which settled to the ocean floor.

Cell theory The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.ver a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1838.
