Question

describe association of azolla and anabaena

Answer 1

There are many examples of plants, bacteria and algae that have formed intimate symbiotic associations or "marriages" with each other. ... But one of the most fascinating of all plant marriages involves a tiny aquatic water fern (Azolla) and a microscopic filamentous blue-green alga or cyanobacterium (Anabaena azollae).

Answer 2

Association of Azolla and Anabaena:

Anabaena Azollae is a little filamentous phototrophic cyanobacterium for the most part observed as a multicellular life form with two unmistakable, reliant cell types.

• The first is a little, round, photoautotrophic "vegetative" cell that performs oxygenic photosynthesis and is commonly blue-green in shading.

• The second is a heterocyst, a bigger, paler, progressively homogenous cell delivered by Anabaena to fix climatic nitrogen.  

• A. Azollae, in spite of the fact that it can exist without anyone else, is generally found inside ovoid pits inside the leaves of the water greenery Azolla. Azolla (otherwise called mosquito plant, duckweed plant, or pixie greenery) is a class of normal water fern whose little leaves gather on the outside of waterways making mats.  

• B. Azollae and Azolla have framed an advantageous relationship where the cyanobacterium gets carbon and nitrogen sources from the plant in return for fixed nitrogen. This relationship has demonstrated to be valuable to people in the creation of sustenance; explicitly in the treatment of rice paddies.
