Which part of a plant serves as home for nitrogen fixing bacteria?
Nodules
What type of plants have root nodules?
Root nodules are swollen structures present present in roots of leguminous plant which belong to family Fabaceae e.g. Pisum sativum , Medicago , Arachis . This family is the second largest family of Dicots and second most important family from economic point of view.These root nodules are formed by Bacteria named Rhizobium. These Bacteria are nitrogen fixing bacteria i.e. they trap N2 from air and convert it into NO3 which is used as fertilizer by plants. There is symbiotic relation between legume roots and N2 fixing Bacteria .They increase soil fertility .
What do root nodules help the plant obtain?
Root nodules contain nitrogen fixing bacteria which help a plant to obtain nitrogen compounds, which are needed for the production of protein (and although plants do not contain as much protein as animals do, they still need a certain amount of it).
What kind of bacteria annually save farmers millions of dollars in fertilizer costs?
Bacteria which are part of the Rhizobia family can "fix" nitrogen in the soil when living in a symbiotic relationship with a legume (Fabaceae) plant. The bacteria live in nodules which form on the roots of the plants, converting atmospheric nitrogen into a plant-usable form which is left in the soil for the next crop. Nitrogen is the most-needed crop nutrient of all the fertilizers, and is frequently the most expensive fertility cost for the farmer.
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.

Nodules
If Bacteria live in the nodules of plant roots Which cycle depends on the bacteria in these nodules?
Nitrogen cycle
Which statement best describes the process that takes place in these nodules?
The correct answer is... Bacteria in the plant nodules convert nitrogen from the soil into molecules the plant can use.
Root nodules are associations between bacteria and plant roots responsible for?
nitrogen fixation, like legumes
Which part a plant serves as a home for nitrogen-fixing bacteria?
nodules
What is the symbiotic relationship legume plants and rhizobium bacteria?
The bacteria live in the plant cells, located on the root, and form nodules. These nodules convert nitrogen gas in the soil to usable energy for the plant. In return, the bacteria have a safe place to live and reproduce.
What is the purpose of legume nodules?
They are caused by a symbiotic bacteria which benefits the plant by fixing atmospheric nitrogen (which the plant needs to make proteins).
What gas is taken up in cellular respiration by soybeans?
Nitrogen from the air is absorbed by the bacteria present in the root nodules of the plant in a symbiotic relationship in which the bacteria provide nitrogen for the soybean's growth in exchange for some nutrients (mostly sugars) that flow in the plant's roots and that the bacteria need for its own growth.

Which organisms play the largest role in changing atmospheric nitrogen into a form that most living things can use?
Bacteria - which are usually found in the root nodules of legumes and have a symbiotic relationship with the plant.
What is the mutualistic relationship between legumes and nodule bacteria?
They are caused by a symbiotic bacteria which benefits the plant by fixing atmospheric nitrogen (which the plant needs to make proteins).
What might you hypothesize why one of the types of plants produced nodules with many bacteria in them and the other type of plant did not?
Nodulation in the roots of plant is a symbiotic bacterial activity and is very common in Legumenous plants, other than legume plants do not allow bacteria to establish this relationship hence nodule formation is prohibited.
