Carl Nägeli
Carl Wilhelm von Nägeli (26 or 27 March 1817 – 10 May 1891) was a Swiss botanist. He studied cell division and pollination but became known as the man who discouraged Gregor Mendel from further work on genetics. He rejected natural selection as a mechanism of evolution, favouring orthogenesis driven by a supposed "inner perfecting principle". Birth and education Nägeli was born in Kilchberg near Zürich, where he studied medicine at the University of Zürich. From 1839, he studied botany under A. P. de Candolle at Geneva, and graduated with a botanical thesis at Zürich in 1840. His attention having been directed by Matthias Jakob Schleiden, then professor of botany at Jena, to the microscopical study of plants, he engaged more particularly in that branch of research. He also coined the term "meristematic tissue" in 1858. Academic career Soon after graduation he became Privatdozent and subsequently professor extraordinary, in the University of Zürich; later he wa ...

Simon Mawer
Simon Mawer ( ; 18 September 1948 – 12 February 2025) was a British author who lived in Italy. Early life and work Born in England and educated at Millfield School in Somerset and at Brasenose College, Oxford, Mawer took a degree in zoology and worked as a biology teacher for most of his life. He published his first novel, ''Chimera'', (Hamish Hamilton, 1989) at the comparatively late age of forty-one. It won the McKitterick Prize for a first novel by an author over the age of forty. ''Mendel's Dwarf'' (1997) followed three works of modest success and established him as a writer of note on both sides of the Atlantic. ''The New York Times'' described it as a "thematically ambitious and witty novel". Uzo optioned film rights, and then later Barbra Streisand optioned them. The novels ''The Gospel of Judas'' (2000) and ''The Fall'' (2003) came next, followed by ''Swimming to Ithaca'' (2006), a novel partially inspired by his childhood on the island of Cyprus. He then published a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisum Sativum
Pea (''pisum'' in Latin) is a pulse or fodder crop, but the word often refers to the seed or sometimes the pod of this flowering plant species. Peas are eaten as a vegetable. Carl Linnaeus gave the species the scientific name ''Pisum sativum'' in 1753 (meaning cultivated pea). Some sources now treat it as ''Lathyrus oleraceus''; however the need and justification for the change is disputed. Each pod contains several seeds (peas), which can have green or yellow cotyledons when mature. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a "pea" flower. The name is also used to describe other edible seeds from the Fabaceae such as the pigeon pea (''Cajanus cajan''), the cowpea (''Vigna unguiculata''), the seeds from several species of '' Lathyrus'' and is used as a compound form - for instance, in Sturt's desert pea. Peas are annual plants, with a life cycle of one year. They are a cool-season crop grown in many parts of the world; planti ...

Royal Bavarian Academy Of Sciences
The Bavarian Academy of Sciences and Humanities () is an independent public institution, located in Munich. It appoints scholars whose research has contributed considerably to the increase of knowledge within their subject. The general goal of the academy is the promotion of interdisciplinary encounters and contacts and the cooperation of representatives of different subjects. History On 12 October 1758 the lawyer Johann Georg von Lori (1723–1787), Privy Counsellor at the College of Coinage and Mining in Munich, founded the ''Bayerische Gelehrte Gesellschaft'' (Learned Society of Bavaria). This led to the foundation by Maximilian III Joseph, Elector of Bavaria, of the Bavarian Academy of Sciences and Humanities on 28 March 1759. Count Sigmund von Haimhausen was the first president. The Academy's foundation charter specifically mentions the Parnassus Boicus, an earlier learned society. Originally, the Academy consisted of two divisions, the Class for History (''Historische ...

Microsporidia
Microsporidia are a group of spore-forming unicellular parasites. These spores contain an extrusion apparatus that has a coiled polar tube ending in an anchoring disc at the apical part of the spore.Franzen, C. (2005). How do Microsporidia invade cells?. Folia Parasitologica, 52(1–2), 36–40. doi.org/10.14411/fp.2005.005 They were once considered protozoans or protists, but are now known to be fungi, or a sister group to true fungi. These fungal microbes are obligate eukaryotic parasites that use a unique mechanism to infect host cells. They have recently been discovered in a 2017 Cornell study to infect Coleoptera (beetles) on a large scale. So far, about 1500 of the probably more than one million species are named. Microsporidia are restricted to animal hosts, and all major groups of animals host microsporidia. Most infect insects, but they are also responsible for common diseases of crustaceans and fish. The named species of microsporidia usually infect one host species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Remak
Robert Remak (26 July 1815 – 29 August 1865) was an embryologist, physiologist and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. as well as several other key discoveries. According to historian Paul Weindling, Rudolf Virchow, one of the founders of modern cell theory, plagiarized Remak's notion that all cells come from pre-existing cells. Remak had concluded this after observing red blood cells from chicken embryos in various stages of division. He then confirmed that the phenomenon existed in the cell of every frog's egg immediately after fertilization, proving that this was a universal phenomenon and finally explaining the reason for the results of tests by Louis Pasteur which had previously proved that there exists no spontaneous generation of life. Remak obtained his medical degree from Friedrich Wilhelm University in Berlin (now Humboldt University of Berlin) in 1838 specializing in neurology. He ...

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
