Question

blue green algae structure specialised for nitrogen fixation ​is​

Answer 1

Answer:

In blue green algae heterocytes structure specialized aerobic fixation. The heterocysts function as the sites for nitrogen fixation under aerobic conditions. They are formed in response to a lack of fixed nitrogen (NH4 or NO3).

Answer 2

Blue-green algae are also called Cyanobacteria and have the ability to fix nitrogen.

• Nitrogen-fixing bacteria have the capability to convert atmospheric nitrogen to useable nitrogen that can be used by plants.

• It is noted that almost 90% of fixation is done by Cyanobacteria.

• These bacteria invade the root hairs of the plant. They divide and form root nodules.

• It is within these nodules, the Cyanobacteria are able to convert atmospheric nitrogen to useable nitrogen.

• The important examples are Anabaena and Nostoc.
