Sažetak
Since the effect of aluminium on living beings was little known until recently and it is possible to present a potential danger for freshwater organisms, the aim of this research was to explore its effect on green (Hydra viridissima) and brown (Hydra oligactis) hydra. Hydra is a simple metazoan organism that belongs to the Cnidaria phylum. It consists of ectoderm, mesoglea and gastroderm. Green hydra forms a symbiotic relationship with the endosymbiotic alga Chlorella, harboured inside the gastrodermal myoepithelial cells. Hydras were treated with four concentrations of aluminium sulphate (25, 250, 475, 500 mg/L) in laboratory conditions for three days and compared to the control. Only cellular layers of treated hydras contained the aluminium depositions: in green hydras depositions were found in gastroderm, including algae Chlorella, and in brown hydras they were found in ectoderm. We assume the appearance of these depositions to be the mechanism of cellular detoxication.
