Nitrogen fixation by Nostoc
Explanation:
- Nitrogen fixation in Nostoc occurs through heterocysts.
- Heterocysts are specialized nitrogen-fixing cells formed during nitrogen deficiency by some cyanobacteria.
- They can fix nitrogen from the atmosphere using the enzyme nitrogenase.
- Nitrogenase can only work in anaerobic condition, so heterocyst must create an anaerobic condition.
- Nostoc takes nitrogen from the atmosphere and fixes it into a form that plants and animals can use it.
