Why are The bacteria that live within the roots of a soybean plant are a critical part of of the nitrogen cycle?
The bacteria that live within the roots of soybean plants, specifically rhizobia, play a crucial role in the nitrogen cycle by converting atmospheric nitrogen into a form that is usable by plants, a process known as nitrogen fixation. This symbiotic relationship allows soybeans to thrive in nitrogen-poor soils and contributes to soil fertility. As soybeans and other legumes are harvested, they enrich the soil with nitrogen, benefiting subsequent crops and promoting sustainable agricultural practices. Thus, these bacteria are essential for maintaining ecosystem health and agricultural productivity.

Nitrogen is biochemically fixed within the soil by?
Nitrogen is biochemically fixed within the soil primarily by certain species of bacteria. These bacteria convert atmospheric nitrogen into a form that plants can use, through a process known as nitrogen fixation. This process is essential for making nitrogen available to plants for growth and development.
Which bacteria live in soil and fix nitrogen as part of the nitrogen cycle?
Leguminous plants contain symbiotic bacteria called Rhizobia within nodules root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilise the soil.
Why are bacteria important in the carbon nitrogen and phosphorus cycle?
Bacteria play a crucial role in the carbon, nitrogen, and phosphorus cycles by facilitating the transformation and recycling of these essential nutrients within ecosystems. In the carbon cycle, bacteria decompose organic matter, releasing carbon dioxide through respiration and contributing to soil health. In the nitrogen cycle, nitrogen-fixing bacteria convert atmospheric nitrogen into forms usable by plants, while nitrifying and denitrifying bacteria help convert nitrogen compounds through various stages, maintaining soil fertility. Similarly, in the phosphorus cycle, bacteria help solubilize phosphorus, making it accessible to plants, thus supporting overall ecosystem productivity.
Why legiminous plants have root nodules?
Leguminous plants have root nodules because they form a symbiotic relationship with nitrogen-fixing bacteria, usually of the genus Rhizobium, that reside within these nodules. The bacteria convert atmospheric nitrogen into a form that the plant can use for growth, providing the plant with a vital source of nitrogen while the bacteria receive nutrients from the plant.
What is the right sequence of steps during infection of plants by nitrogen-fixing bacteria?
During the infection of plants by nitrogen-fixing bacteria, the process typically begins with the recognition of the bacteria by the plant roots, often facilitated by root exudates. This recognition triggers the formation of root nodules, where the bacteria enter and establish a symbiotic relationship. Next, the bacteria are encapsulated within the plant cells, leading to the differentiation of both the plant and bacteria for mutual benefit, ultimately resulting in nitrogen fixation. Throughout this process, signaling molecules play a crucial role in coordinating the interactions between the plant and the bacteria.

Which parts of the natural environment carry out nitrogen fixation?
Legumes; possess nodules located within their roots that are packed with Nitrogen-Fixing bacteria. So the Answer is: leguminous [root-bound] nodules.
Why legiminous plants have root nodules?
Leguminous plants have root nodules because they form a symbiotic relationship with nitrogen-fixing bacteria, usually of the genus Rhizobium, that reside within these nodules. The bacteria convert atmospheric nitrogen into a form that the plant can use for growth, providing the plant with a vital source of nitrogen while the bacteria receive nutrients from the plant.
What is the difference between symbiotic and asymbiotic nitrogen fixation?
Symbiotic nitrogen fixation occurs when nitrogen-fixing bacteria form a mutually beneficial relationship with plants, typically within nodules on plant roots. Asymbiotic nitrogen fixation, on the other hand, happens in free-living bacteria in the soil or water that can fix nitrogen without the need for a specific plant host.
Nitrogen fixing bacteria live symbiotically in what?
Nitrogen fixing bacteria live symbiotically in the root nodules of leguminous plants such as peas, beans, and clover. This symbiotic relationship allows the bacteria to convert atmospheric nitrogen into a form that the plant can use for growth, while the plant provides the bacteria with nutrients and shelter.
What type of bacteria is found in legumes?
Special class of bacteria called Rhizomes live on the roots of leguminus plants. They take free nitrate and nitrites from the environment and change to a form that can be readily used by plants. Relationship between nitrogen fixing bacteria and plants is called Symbiosis.
What organisms perform nitrogen fixation?
There is a bacterium that resides within the rhizomes - nodules found within the roots - of Legumes that transforms atmospheric N2 [gaseous molecular Nitrogen] into its forms [NO2 and NO3] that are biochemically active.
How do plants get the nitrogen?
Although nitrogen is abundant in the atmosphere, atmospheric nitrogen features a triple bond that is difficult to break. Bacteria in the soil are mainly responsible for breaking this bond to create organic nitrates that are used by the plants. Such bacteria are called "nitrogen-fixing bacteria" because they take nitrogen from the air (N2) and "fix" it into ammonium (NH4+). Then other bacteria called nitrifying bacteria convert this ammonium to nitrate and nitrite. The nitrates are assimilated by plants through the root systems and incorporate them into nucleic acids and proteins. Animals eat these plants and can use the nitrogen stored within. Then the consumers further up the trophic levels can obtain their nitrogen from the herbivores.
The main purpose of DNA is to store information. Where is information stored within a DNA molecule?
It is stored within the sequence of nitrogen bases.
