vegetative cells (19:1). The vegetative cells and akinetes of
Nostoc
PCC 7524 contained approximately
the same amounts of DNA and RNA (Sutherland

., 1979).
5) Metabolic activities
:
The metabolic activities of isolated akinetes of cyanobacteria differed
from one another. In general, a lowering of photosynthetic activity was noted in the akinetes of
