What is the relationship between the plant and bacteria in root nodules?
The nodules contain bacteria which can convert atmospheric nitrogen into ammonia
What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
What form of nitrogen is produced by bacteria - in certain plant root nodules?
These bacteria, through the plant, receive elemental nitrogen from the air, and use it to produce ammonia (NH3). This process is called nitrogen fixation. The ammonia can then be converted in to oxides of nitrogen and nitrogen salts, such as nitrites and nitrates, which are used by the host plant and others as nutrients.
What two functions of bacteria in the nitrogen cycle?
Bacteria function in the nitrogen cycle as nitrogen fixers and denitrifiers. Nitrogen fixing bacteria take in atrmospheric nitrogen gas and "fix" it into a nitrate or nitrite that can be used by plants. Denitrifiers decompose dead plant tissues and release nitrogen to the atmosphere.
What does certain bacteria that live on the roots of plants provide for the plant?
I think you are thinking of nitrogen fixing bacteria which are associated with nodules on the roots of plants belonging to the legume family (peas and beans). The bacteria that form and live in these nodules have the ability to take nitrogen form the air and use it to build organic molecules directly. This is important because all life needs a small amount of nitrogen (in organic forms) to build proteins.
What do nitogen-fixing bacteria do?
Nitrogen fixing bacteria change nitrogen from the air into nitrogen compounds such as ammonia, nitrate, and nitrogen dioxide. They do so, through two living arrangements. One's as free living bacteria in the soil. The other's in association with plants of the Fabaceae and Leguminosae families, such as beans and peas. In this arrangement, the plant gives the bacteria sugars in the form of exudates [waste products]. In return, the bacteria provides the plant with nitrogen in forms that the plant can take in.
What do nitrogen fixing bacteria convert in the nitrogen cycle?
Nitrogen fixing bacteria are anaerobic bacteria present in the soil or in some plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds (e.g. ammonium salts) that plants can use in the soil.Nitrogen fixing bacteria that are symbiotic with plants use sugars supplied by the plant they live in to provide the metabolic energy to carry out this process.

How does bacteria benefit plants?
Nitrogen fixing bacteria are important for plants as they can convert Nitrogen from the air into Nitrates in the soil which the plant can then use. Legumes have nodules on their roots to provide a suitable habitat for them.
Why it is important that some bacteria in the soil change nitrogen to nitrates?
Because when nitrogen is converted into nitrates, which is a common fertilizer, it provides nutrients for plant
What is symbiotic nitrogen fixation?
Nitrogen fixation occurs in leguminous plant that have nitrogen fixing bacteria in the root nodule. The plants utilize the nitrogen from the nitrogen fixing bacteria. The bacteria utilize plant sugars formed via photosynthesis.

What role do bacteria play during the nitrogen cycle?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycleThey fix nitrogen into forms usable by plants.
How nitrogen enters the atmosphere?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
Where are nitrogen- fixing bacteria found?
Plant roots
