A special type of cell found in certain cyanobacteria (blue-green algae) that is thicker-walled and specialized for nitrogen fixation.
From Greek hetero- (different) and -cyst (cell/pouch), named for its distinctly different appearance and function compared to regular vegetative cells.
Heterocysts are nature's nitrogen factories—these specialized cells can convert atmospheric nitrogen into usable forms that plants need, and they operate in an oxygen-free bubble inside the cyanobacteria, a stunning example of cellular specialization!
