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.
