In plant nitrogen metabolism, a significant role is played not only by the uptake of nitrogen compounds but also by their release into the environment. One of the ways in which plant nitrogen is released is the volatilization of reduced and oxidized nitrogen forms through the above-ground plant...
以这个管理例子和产生结果多数雇员在这些组织成为安全主张自己。 成功的组织产生使角色主要安全提倡者更加容易责任和介入的文化。 [translate] aNitrogen in the form of soil compounds enters plants, which then are consumed by other organisms 氮气以土壤化合物的形式进入植物,由其他有机体然后消耗 [translate] ...
For example, some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes(豆科植物)are especially good at this nitrogen(氮)-fixing. Then any crops that share the same space...
结果1 题目Plants take in ___ from the air. A. oxygen B. carbon dioxide C. nitrogen 相关知识点: 试题来源: 解析 B。植物从空气中吸收二氧化碳进行光合作用。氧气是植物产生的,氮气一般不是植物直接从空气中大量吸收用于生长的。反馈 收藏
Therefore, the preferred form in which nitrogen is taken up depends on plant adaptation to soil conditions. Generally, plants adapted to low pH and reducing soils as found in mature forests or arctic tundra tend to take up ammonium or amino acids, whereas plants adapted to higher pH and more...
Current studies suggest that many plants are able to take up not only inorganic nitrogen (N) but also organic N. We used the novel tool of position-specific isotope labeling to improve the quantification of intact amino acid uptake and to deepen our understanding of the processes occurring at ...
aNitrogen is present as nitrate salts or urea, which dissolve in water into the nitrate ion (among other things). Phosphorus is incorporated as phosphate, which provides the phosphate ion. Potassium is generally in the form of potash, which ... well off-hand I forget what the form of pota...
Take nitrogen from the air and combine it with oxygen to make it usable to the plant Legumes Soybeans, clover, alfalfa, beans, peas Healthy Roots Roots are white or nearly white, and smell fresh. Unhealthy Roots Roots are black, brown, or dark orange and smell rotten and sour. Terminal ...
