Plasmolysis in Characeae

Abstract

Internodal and “branchlet” cells of Characeae can be plasmolysed by Ca(NO3)2 during as long as 1-10 weeks while keeping the protoplasmic streaming active. In the course of the long-lasting plasmolysis the protoplasts are subjected to a remarkable deformation, and concomitantly, the streaming pattern of protoplasm suffers pronounced modifications.
