Question

name the nitrogen fixing alga?list some other uses of algae.​

Answer 1

Answer:

Blue—green algae (Cyanobacteria) are a special group of prokaryotes. They have chlorophyll and phycobiliprotein and can fix carbon by oxygen-evolution photosynthesis like plants; and their genome contains nucleotide sequences which are comparable with that of 16S and 5S rRNA of cubacteria. Therefore, in tradition, they are called Cyanophyta (Myxophyta, Cyanophyceae), but in the recent decade, they are also called Cyanobacteria. (According to the “Manual of Systematic Bacteriology” Vol. 3 (1989), they can be called cyanobacteria or blue—green algae or Cyanophyceae). For convenience, I use BGA (blue—green algae) for these prokaryotes in this paper. BGA are widely distributed all over the earth. While fixing carbon from CO2, certain BGA can fix dinitrogen from the atmosphere, and are called nitrogen-fixing BGA, including free living and symbiotic forms.

Answer 2

•Nitrogen fixing is a process by which molecular nitrogen in the air are able to fix atmospheric nitrogen. This was the first specie of ozotobactus genus. One nitrogen fixing algae is BGA ( Blue - Green Algae)

• Cyano bacteria is called Blue - Green Algae . Heterogenous group of procaryotic principally photosynthesis organism.

USES OF ALGAE

• Algae are rich source of carbohydrate , protein , enzyme and fyber . Many fiber like Vitamic A , C , B1 , B2 , B6 is found.

• Algae are supose to be used in producing nutritional supplement. Seaweed is an important food supplement for animals.

• Algae are used for fertilization of crop as they provide rich source of nutrient in organic matter.
