What are nodules ?how are they help full
Answers
Answer:Root nodules are extra lobes of certain plants such as peas and beans in which nitrogen-fixing bacteria are found. ... Bacteria in these root nodules convert the atmospheric nitrogen into nitrates which the plants can utilize. The plants use this nitrogen to synthesis proteins and other materials
Explanation:
The purpose of these nodules is a) The nodules contain bacteria which can convert atmospheric nitrogen into ammonia.
Leguminous plants fix atmospheric nitrogen, through a symbiotic association with bacteria, by converting it into ammonia. Nitrogen is required to produce proteins and nucleic acids and most plants acquire it through nitrogen rich fertilizers.
Roots of leguminous plants allow the invasion nitrogen fixing bacteria (Rhizobium), these organisms then multiply to form nodules. The mutualism between the two organisms is maintained as the bacteria provides nitrogen and receives shelter, to and from the plant respectively.
hope its helpful
pls mark as brainliest
Answer:
they contain symbiotic bacteria called rizobia within nodules, producing nitrogen components which helps to plant grows when the plant dies, the fixed nitrogen is released making it available to other plants and its help to fertilize the soil
