These are important reasons to consider Si among research topics in biology, to describe its participation in metabolic processes. El silicio es un elemento no metálico y al mismo tiempo metaloide que viene representado por el símbolo químico Si. A role of Si has also been observed on animals, especially in some processes like bone formation and immune response. El silicio tiene un punto de fusin de 1,411 C, una densidad relativa de 2,33 (g/ml) y un punto de ebullicin de 2355 C.Su masa atmica es de 28,086 u (unidad de masa atmica). Resumen en espaol En el presente trabajo se aborda el aumento del ndice de. Even though a genetic base for absorption and accumulation of Si has been found, there is still much to explore on the role of Si on plants at the biochemical and physiological level. Esto constituye el 27,72 de los slidos cr ust, mientras que el oxgeno constituye el 46,6 y el elemento que sigue al silicio es el aluminio que es el 8,13. Sample records for OXIDOS DE SILICIO (silicon oxides) from. Si also confers plant resistance to biotic and abiotic stress. In the case of vascular plants, the absence of Si has been shown to increase their vulnerability to pathogens and insects. Si presence has proven to be of importance in some unicellular organisms such as diatoms and in other multicellular sea living organisms such as sponges, in addition to some Equisetaceae and other plants of relevance to man, such as rice, sugar cane and pumpkin. It is expected that this element should have some effect on living organisms, given the abundance of Si on the planet and the fact that it is believed to have existed at even higher concentrations at the beginnings of life. The interest on the study of silicon (Si) effects on living organisms has recently increased.
