The correct answer is:
Grow a legume crop to support the development of root nodule
The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil.
Explanation:
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.
The Nucleus is separated from the cell’s cytoplasm by a
membrane. The nucleus contains hereditary materials made of plenty proteins and
DNA. The nucleus directs all cell activities. Nucleus is commonly found in
Eukaryotic cells. The genetic materials found in the Nucleus is organized as
DNA molecules, together with a wide array of proteins, which causes to form
chromosomes.
