WebApr 17, 2024 · Both elements are brittle and have a metallic luster. Each of these elements has an outer electron shell that contains four electrons; this property of silicon and germanium makes it difficult for either element in its purest form to be a good electrical conductor. One way to cause a metalloid to conduct electric current freely is to heat it up. WebMonocots and dicots differ in their boron (B) requirement, but also in their capacity to accumulate silicon (Si). Although an ameliorative effect of Si on B toxicity has been reported in various crops, differences among monocots and dicots are not clear, in particular in light of their ability to retain B in the leaf apoplast. In hydroponic experiments under controlled …
