Summary

The reserve polysaccharides in chloroplasts of several species of Acetabularia have been identified as starch.

The starch granules in situ as well as the isolated and purified particles “stain” with Lugol-reagent. They show the characteristic birefringence.

Acid hydrolysis and degradation by α-amylase followed by acid hydrolysis showed that the starch is composed only of glucose units.

The statements of Vanden Driessche and Bonotto (1967) concerning the inulin character of the reserve polysaccharides in Acetabularia chloroplasts need correction.
