Jean Senebier
Jean Senebier (25 May 1742 – 22 July 1809) was a Republic and Canton of Geneva#History, Genevan Calvinist pastor and naturalist. He was chief librarian of the Republic of Geneva. A pioneer in the field of photosynthesis research, he provided extensive evidence that plants consume carbon dioxide and produced oxygen. He also showed a link between the amount of carbon dioxide available and the amount of oxygen produced and determined that photosynthesis took place at the parenchyma, the green fleshy part of the leaf. Biography Senebier was born in Geneva, the son of a wealthy merchant. He wrote extensively on plant physiology and was one of the major early pioneers of photosynthesis research. Senebier also published on the experimental method, first in 1775, and then in an expanded work, in 1802. His precise definition of the experimental method anticipated the work of noted French physiologist Claude Bernard fifty years later. Senebier also served as chief librarian of the R ...

Canton Of Geneva
The Canton of Geneva, officially the Republic and Canton of Geneva, is one of the Cantons of Switzerland, 26 cantons of the Switzerland, Swiss Confederation. It is composed of forty-five Municipality, municipalities, and the seat of the government and parliament is in the Geneva, city of Geneva. Geneva is the French-speaking westernmost canton of Switzerland. It lies at the western end of Lake Geneva and on both sides of the Rhone, its main river. Within the country, the canton borders Vaud to the east, the only adjacent canton. However, most of Geneva's border is with France, specifically the region of Auvergne-Rhône-Alpes. As is the case in several other Swiss cantons (Ticino, canton of Neuchâtel, Neuchâtel, and canton of Jura, Jura), Geneva is referred to as a republic within the Swiss Confederation. One of the most populated cantons, Geneva is considered one of the most cosmopolitan regions of the country. As a center of the Calvinism, Calvinist Protestant Reformation, Re ...

His father Jean Huber (1721–1786) was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jan Ingenhousz
Jan Ingenhousz FRS (8 December 1730 – 7 September 1799) was a Dutch-British physiologist, biologist and chemist. He is best known for discovering photosynthesis by showing that light is essential to the process by which green plants absorb carbon dioxide and release oxygen. He also discovered that plants, like animals, have cellular respiration. In his lifetime he was known for successfully inoculating the members of the Habsburg family in Vienna against smallpox in 1768 and subsequently being the private counsellor and personal physician to the Austrian Empress Maria Theresa. Early life He was born into the patrician Ingen Housz family in Breda in Staats-Brabant in the Dutch Republic. From the age of 16, Ingenhousz studied medicine at the University of Leuven, as the Protestant Universities were not then open to Catholics like himself, where he obtained his MD in 1753. He studied for two more years at the University of Leiden, where he attended lectures by, among othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Priestley
Joseph Priestley (; 24 March 1733 – 6 February 1804) was an English chemist, Unitarian, Natural philosophy, natural philosopher, English Separatist, separatist theologian, Linguist, grammarian, multi-subject educator and Classical liberalism, classical liberal Political philosophy, political theorist. He published over 150 works, and conducted experiments in several areas of science. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. Priestley's science was ...

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Chemistry#Subdisciplines, subdisciplines of chemistry. Materials science, Materials scientists and metallurgists sha ...

Marcello Malpighi
Marcello Malpighi (10 March 1628 – 30 November 1694) was an Italians, Italian biologist and physician, who is referred to as the "founder of microscopical anatomy, histology and father of physiology and embryology". Malpighi's name is borne by several physiological features related to the biological excretory system, such as the Renal corpuscles, Malpighian corpuscles and Renal pyramids, Malpighian pyramids of the kidneys and the Malpighian tubule system of insects. The White pulp, splenic lymphoid nodules are often called the "Malpighian bodies of the spleen" or White pulp, Malpighian corpuscles. The botanical family Malpighiaceae is also named after him. He was the first person to see capillaries in animals, and he discovered the link between arteries and veins that had eluded William Harvey. Malpighi was one of the earliest people to observe red blood cells under a microscope, after Jan Swammerdam. His treatise ''De polypo cordis'' (1666) was important for understanding blood ...
