Nostoc (Blue Green Algae) – Structure, Reproduction and Importance

Nostoc is a filamentous cyanobacterium (blue-green algae) commonly found in moist soil, freshwater ponds, and symbiotic associations with plants like Cycas and Anthoceros. In this video, we explain the structure of Nostoc, heterocyst formation, nitrogen fixation, and asexual reproduction in a simple and clear way for biology students.

You will learn about:
• Structure of Nostoc colony
• Vegetative cells and heterocyst cells
• Nitrogen fixation by nitrogenase enzyme
• Asexual reproduction through fragmentation and hormogonia
• Symbiotic association of Nostoc with plants
