Cyanobacterial Heterocysts

• Anabaena differentiates into specialized cells called heterocysts.

•

• - Allow it to fix nitrogen anaerobically while maintaining oxygenic photosynthesis

Fruiting Bodies• Myxococcus xanthus uses gliding motility.• - Starvation triggers the aggregation of

100,000 cells, which form a fruiting body.
