Explanation:
Detailed explanation-1: -The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.
Detailed explanation-2: -Nitrogen-fixing bacteria convert atmospheric nitrogen gas, which is almost inert, into solid nitrogen compounds that can then be absorbed by plants. These bacteria help fertilize the plants.
