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. In this theory the internal contents of cells were called protoplasm and described as a jelly-like substance, sometimes called living jelly.
Eukaryotic cells contain organelles including mitochondria, which provide energy for cell functions; chloroplasts, which create sugars by photosynthesis, in plants; and ribosomes, which synthesise proteins. Cells were discovered by Robert Hooke in 1665, who named them after their resemblance to cells inhabited by Christian monks in a monastery.
Christian René Marie Joseph, Viscount de Duve (2 October 1917 – 4 May 2013) was a Nobel Prize-winning Belgian cytologist and biochemist. [1] He made serendipitous discoveries of two cell organelles, peroxisomes and lysosomes, for which he shared the Nobel Prize in Physiology or Medicine in 1974 with Albert Claude and George E. Palade ("for their discoveries concerning the structural and ...
English scientist Robert Hooke discovered cells in 1665, looking at cork under a microscope. He introduced the word cell because the patterns made by the cellulose walls of dead cork reminded him ...
[13] [14] Hooke coined the term "cell", suggesting a resemblance between plant structures and honeycomb cells. [137] The hand-crafted, leather-and-gold-tooled microscope he designed and used to make the observations for Micrographia, which Christopher Cock made for him in London, is on display at the National Museum of Health and Medicine in ...
In 1935, Karl Lohmann discovered ATP and its role as a source of energy for cells, so the concept of a metabolically-driven sodium pump was proposed. The tremendous success of Hodgkin , Huxley , and Katz in the development of the membrane theory of cellular membrane potentials , with differential equations that modeled the phenomena correctly ...
Theodor Schwann (German pronunciation: [ˈteːodoːɐ̯ ˈʃvan]; [1] [2] 7 December 1810 – 11 January 1882) was a German physician and physiologist. [3] His most significant contribution to biology is considered to be the extension of cell theory to animals.
Anthony Binfield was 30 years old when he was found in his cell on 6 March 2023, just weeks after Lowdham Grange changed hands. He had first arrived at the jail in August 2021, and after a short ...
