Anabaena Occurrence: Anabaena is a class of filamentous cyanobacteria, or blue green growth. It found as microscopic fish. It is known for its nitrogen settling capacities. They shape cooperative associations with specific plants, for example, the mosquito plant. A few types of Anabaena are endophytes. They live in the underlying foundations of Cycas and Azolla Anabaena is found in a ...

PRODUCTS OF PHOTOSYNTHESIS The products or result of photosynthesis are the carbohydrates and oxygen. Four starches, D-glucose. D-fructose, sucrose and starch are regularly are framed in the green cells in photosynthesis. Plant physiologists and natural chemists have attempted to locate the primary result of this procedure. Yet at the same time it is not clear which the principal result of ...

Factors Affecting Photosynthesis Light And Photosynthesis Light is an important factor as photosynthesis does not take place in dark. When considering effect of light on photosynthesis it is important to distinguish between the effects of light intensity and light quality. Light Quality The light consists of rays of different wavelengths. The study of absorption spectrum revealed that only red and blue ...

Photorespiration Photo-respiration is light dependent uptake of oxygen and output of carbon dioxide. It is not related to the normal respiration and resembles only in that oxygen is used and carbon dioxide produced. Warburg Effect Photosynthesis is believed to have evolved in atmosphere much richer than carbon dioxide than it is today, but one containing little oxygen, probably about 0.02% ...

CAM Plants Dark Fixation of carbon Dioxide Many species living in arid climates have thick leaves and relatively low surface-to-volume ratio and have low transpiration rates. Their cells have large central vacuoles with a thin layer of cytoplasm around them. These plants are called succulents. Another characteristic feature of these plants is that their stomata opens at night and fix ...

Majority of them are fresh water. They are also found on moist soil. They form dark green mats. General structure of Vaucheria Vegetative structure:The thallus is filamentous. The filament is cylindrical, branched, tubular, erect coenocytic. The filament is attached to the substratum by hepteron. Hepteron is colourless branched rhizoid like structure. Filament increases in length by apical growth. Cross walls are ...

Calvin Benson Cycle Dark reaction involves conversion of carbon dioxide into carbohydrate. It occurs in the stroma of the chloroplast and involves many reactions, each catalyzed by a different enzyme. The dark reactions require the products of light step (ATP and NADPH2), but does not itself requires light. This is why it is referred to as dark reaction. C-3 Plants ...

Photophosphorylation The production of ATP in the chloroplast or in the other membranes during light reaction is called photophosphorylation. Photophosphorylation occurs in ATP-synthase complex or coupling factor (CF) located in stroma thylakoid membranes. The coupling factor is also responsible for transport of H+ from the thylakoid channel to the stroma. The electron transfer during photophosphorylation takes place firstly when the ...

Hill Reaction Chloroplasts contained the naturally occurring electron acceptor NADP+ and that it was reduced to NADPH2 in the light by addition of electrons and hydrogen ions. The hydrogen ions for the reduction are provide by water molecule which split into hydrogen ions and electrons releasing the oxygen (photolysis of water). The chloroplasts supplied with ADP and inorganic phosphate, manufacture ...

Photo-Systems – The Light Traps The orderly arrangement of photosynthetic pigments on thylakoid membrane is called photo-system. History Hill and Fay Benda11 (1960) proposed that photo-chemical phase of photosynthesis involves two events, one that tended to oxidize the cytochrome and the other that tended to reduce it. It is now known that oxidation is brought by far-red light of wavelengths ...
