English-Ireland (top end) Renown is listed as a verb in Chambers Dictionary. I looked for etymology - the similarity with known is tantalising.... c.1300, from Anglo-Fr. renoun, O.Fr. renon, from renomer make famous, from re- repeatedly + nomer to name, from L. nominare to name..
Photosynthesis is the process whereby plants using light energy from the sun convert carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions. The overall equation for photosynthesis is. carbon dioxide + water =light energy=> glucose + oxygen. 6CO2 + 6H2O =light energy=> C6H12O6 + 6O2. Light energy from the sun is converted into chemical energy by the production of glucose molecules. Photosynthesis is carried out in the chloroplasts of plant cells using the green pigment chlorophyll.
Photosynthesis-Photolysis and Carbon Fixation. - Cell Biology. Photosynthesis is the means that primary producers (mostly plants) can obtain energy via light energy. The energy gained FROM light can be used in various processes mentioned below for the creation of energy that the plant will need to survive and grow. Photosynthesis is a reduction process, where hydrogen is reduced by a coenzyme. This is in contrast to respiration where glucose is oxidised. The process is split INTO two DISTINCT areas, photolysis (the photochemical stage) and the Calvin Cycle (the thermochemical stage).
