Describe evidence to support the cell theory

By early 1800s, the accepted intellection was that appoints and animals were composed of globules called cells. Robert Brown rise this nous by describing the nuclei in cells of orchid founds. In 1838, a German botanist, Matthias Schleiden suggested that cells were the basic structural whole of all plant matter. German zoologist, Theodor Schwann proposed that animals were made up of cells. The both biologists came to recognise that both plant and animal tissues have a cellular organization. This basic fancy of Schleidan and Schwann was published in 1839 and is cognize as the cell guessing: - stalls atomic number 18 the smallest units of life - All live things are made of cells A German doctor, Rudolf Virchow added to the understanding of cells by providing a new answer to the walk: How are living things produced? sometime(prenominal) answers included unrehearsed generation, the psyche that living things arose from non-living or beat(p) matter. Virchow challenged these old ideas with his concept of biogenesis (bio=life; genesis=origin, creation). He proposed that new cells came from pre-existing cells, which was contributed into the Cell Theory.

In1862, French biologist, Louis Pasteur carried out an try that disproved the old idea of involuntary generation. His experiment involved swan-necked flasks, extend to air. It was then heated and cooled slowly. The swan-necks unploughed new micro-organisms from falling into the alimental medium in the flasks, so having no new gain ever appearing. Hence pecuniary support the view that cells are produced from pre-existing cells. If you want to take out a full essay, say it on our website: Orderessay
