PHOTORESPIRATION PHOTORESPIRATION first demonstrated by Decker in 1955 and 1959. ‘The Photorespiration defined as “the Respiration that occurs in green cells in the presence of light resulting into excess evolution of CO2” OR “The release of CO2 in Respiration in presence of light.” Always required light to perform. The photorespiration rate of reaction takes place … Read more

Plant Hormones In 1905, the British physician E. H. Starling introduced the term hormone Plants are multicellular complex organisms, to grow themselves they require coordination between cells about their activities, cells must be able to communicate with each other. So the principal means of intercellular communication within plants are the hormones. Hormones are molecular signals that … Read more

What is Soil? Soil is the loose surface of the earth and it’s the material that covers most of the land and area. It consists of inorganic particles and organic matter. In India, soil classification varied because of physical, chemical, biological, and fertility properties of soil as studies stated. Decades have been passed scientist and … Read more
Chlorosis: A deficiency of chlorophyll (natural compound present in green plants that gives them their color) causes chlorosis, a yellowing of leaf tissue. Poor drainage, damaged roots, compacted roots, high alkalinity, and nutrient shortages in the plant are all possible causes of chlorosis. Nutrient deficits can result from a lack of nutrients in the soil … Read more
Differences between Pigment System I and Pigment System II Pigment System I (PS I) Pigment System II (PS II) PS I is made up of about 200 to 400 chlorophyll molecules; 50 carotenoid molecules; one molecule of reaction centre P700 (Chl.a700), Plastocyanin, Cytochrome f each; two molecules of Cyt. b563 (Cyt b6) and one … Read more

PHOTOSYNTHESIS It is an anabolic process. Carbohydrates are synthesized. Light energy is stored in the form of glucose or chemical energy. The amount of CO2 in the air decreases during photosynthesis. It takes place only in chlorophyllous cells. It occurs only in the light. The dry weight of the plant increases. Photophosphorylation occurs. 6CO2+12H2O——–> + … Read more
RESPIRATORY QUOTIENT The ratio of the volumes of CO2 liberated and O2 used during respiration in a given period of time. Also called the respiratory coefficient. PHOTOSYNTHETIC QUOTIENT The ratio of the volumes of O2 evolved and CO2 absorbed during photosynthesis in a given period of time. DIFFERENCE BETWEEN RESPIRATORY QUOTIENT AND PHOTOSYNTHETIC QUOTIENT Respiratory … Read more
