MP3 Players - PowerPoint Presentation Example s, I searched the internet to find the detailed specifications of the mp3 players I and other acquaintances were familiar with and using them in practical life. I was already familiar with the software which comes as a part and parcel of the operating systems like Windows Media Player and Itunes by Apple. Third party software came as additional add-ons with other software packages of sound cards and speaker systems for computers. Moreover such third party mp3 software are frequently advertised on various web sites. The software industry is primarily focused on developing media rich web sites where entertainment can be at your fingertips. When computers are inaccessible or cannot be carried along, like on mountaineering trips and other outdoor excursions then the portable mp3 players come into the picture. Advanced electronics technology has miniaturized the music players while retaining the sound quality along with long lasting power packs so that music can be enjoyed in all sorts of places and circumstances. The software was developed concurrently with the operating systems and has become more functional, error free and user friendly along the course of history.

What Role does Bundle Sheaths Play in C4 Plants Essay

What Role does Bundle Sheaths Play in C4 Plants - Essay Example Bundle sheath cells are the major site of refixation of the CO2 and C4 acid decarboxylation. The mesophyll cells also concentrate the CO2 and send it to the bundle sheath cells. NADP-malic enzyme (NADP-ME) and phosphoenolpyruvate carboxykinase (PCK) are expressed in the bundle sheath cells of the C4 plants. They are the major enzymes responsible for the refixation of the CO2 from the C4 acid. (Nomura et al. 2005). In C4 leaves, each vein is surrounded by a ring of the bundle sheath cells surrounded again by the mesophyll cells. These bundle sheaths have the chloroplasts arranged centrifugally with the large starch granules and unstacked thylakoid membranes. In the bundle sheath cells ribulose-1,5-bis-phosphate carboxylase/oxygenase (Rubisco) enzyme accumulates extensively. The specific enzyme activity can be easily determined by using the non aqueous fractionation techniques and pulse labeling techniques. (Majeran et al. 2005).
