Intracellular aragonite crystals in the flesh-water alga, Spirogyra sp.
Published online by Cambridge University Press: 05 July 2018
Abstract
Intracellular crystals of aragonite have been identified by selected area electron diffraction (SAED) in the freshwater filamentous alga Spirogyra sp. which grows sporadically as carpets in the Thames river, Ontario, Canada. The crystals are 2 to 24 µm in length, and characterized by a unique cross-shaped morphology, in which needle-like, or prismatic outgrowths develop from a common axis. Crystals may be dispersed through filaments, but tend to cluster as aggregates towards the centre.
