Photosynthesis

Process of photosynthesis is utilized by autotrophic organisms such as green plants, algae and cyanobacteria (photosynthetic bacteria). They use the photosynthesis process step by step in order to make their own organic nutrients from simple inorganic nutrients (water, carbon dioxide and minerals) and radiant energy. The radiant energy is converted into chemical energy of specific organic compounds, mainly sugars and ...

On the basis of Photoperiodism responses the plants are divided in to different types by Garner & Allard. The short-day flowering plants, long-day flowering plants and day-neutral plants. Short-Day Flowering Plants The plants that flower when the day length is less than a certain critical length termed as short-day plants (SDPs). These plants require a specific short duration of light period for ...

photosynthesis quiz Describe process of photosynthesis. Write note on action and absorption spectrum. Describe non-cyclic phosphorylation. Describe cyclic phosphorylation. Describe cavine cycle. Give factors affecting the rate of photosynthsis. What is the concept of limiting factor? SHORT QUESTIONS: Characterize photosynthsis. photosynthesis quiz Ans: Photosynthesis (photograph light, amalgamation assembling) might be characterized as the procedure in which the green plants incorporate sugars ...

MEASUREMENT OF PHOTOSYNTHESIS The rate of photosynthesis is measured by one of the accompanying strategies: By measuring (I) the volume of CO, devoured (2) volume of oxygen freed (3) measure of starch gathered. 1. OXYGEN EVOLVED It is the easiest strategy. It this case, number of rises of oxygen are excludeed given in unit time by green amphibian plants like ...

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 ...

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 ...

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 ...
