Question

Name the organism that fixes nitrogen in symbiotic association with a water fern. Where does it live in such plants?

Answer 1

Hint: When the nitrogen-fixing bacteria sleep in symbiotic relationships with the host then it's called symbiotic organic process. It's employed by plants like legumes for fixing atmospheric nitrogen gas to ammonia. it's established broadly in nature and has very low economic and environmental costs.

Complete Answer:
- The biological organic process that converts atmospheric nitrogen into the nitrogenous compounds of living organisms is named symbiotic organic process. for instance - Rhizobium, Frankia, etc. Most of the microorganisms partner themselves with host plants to repair nitrogen symbiotically. By the method of photosynthesis, plants provide sugars that are utilized by nitrogen-fixing microorganisms for producing energy that's necessary for organic process.
- The common example of symbiotic organic process is Azolla's symbiosis with a cyanobacterium Anabaena azolla This fixes nitrogen by living in association with aquatic fern. During this process, specialized cells are called heterocyst formed by the actual amount of nitrogen that's fixed by cyanobacteria. In wetlands of Southeast Asia, this sort of symbiosis has been used for the last 1000 years as a bio fertilizer.
- The most crucial symbiotic relationship takes place between legumes and Rhizobium and Brady rhizobium bacteria. This symbiotic association is common within the worldwide ecology. Some samples of legumes that are utilized in the symbiotic organic process are alfalfa, beans, clover, lupines, peanuts, etc.
- In the symbiotic relationship, the availability of nitrogen by bacteria directly takes place within the legume and it indirectly provides nitrogen to the adjacent grass plants.
This Anabaena occurs within the leaves of water ferns.

Note: Prokaryotes can fix nitrogen very easily and efficiently by the method of symbiotic organic process. Thus, most plants are there that provide nutrients to at least one another by making a symbiotic relationship. During this way nutrient requirements of each plant complete. The plants will get the benefit and stop them from getting dead.
