Hint: Bacteria that fix nitrogen, microorganisms that turn the atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). These species, which play an important role in the nitrogen cycle, perform over 90 percent of all nitrogen fixation.
Complete answer: Anabaena cycadae is a BGA that is found in Cycas coralloid roots. Anabaena is a genus that occurs for plankton as filamentous cyanobacteria. It is known for its ability to fix nitrogen and it forms symbiotic connections with plants like mosquito fern. They are one of four kinds of cyanobacteria producing neurotoxins harmful to local ecosystems, as well as livestock and animals. The output, which protects the plant from the pressure from grazing, is supposed to be input in its symbiotic relations.
The entire Anabaena genome, which is 7.2 million base pairs long, has been established in 1999 as a DNA Sequencing project. Heterocysts that turn nitrogen into ammonia were the subject of the research. Some Anabaena species have been used as a natural fertilizer in rice paddy farms. The nitrogen that connects blue-green algae to Anabaena and Nostoc punctiforme, prokaryotic, photosynthetic, and self-propelled blue-green algae is symbiotically associated with the Cycas coralloid root (Cyanobacteria).
Hence, option C-Cycas is the correct answer.
Note: Anabaena, a filamentous cyanobacterium that is commonly found in shallow, nitrogen-fastening waters. They are commonly seen in symbiosis with plants such as mosquito ferns. Anabaena and Azolla manages a symbiotic relationship that supports each other with Azolla water fern. In exchange for nitrogen, it gives cyanobacteria a healthy environment. Cycads are plants with a very long history of fossils, which were once more common and complex. They usually have a solid, wooden trunk with broad, hard, and steep, perennial leaves on their heads. Typically, they have plump leaves.
