Última Functional morphology of the horseshoe spot in the frustule of Planothidium species (Bacillariophyta) IBSS Repository Bukhtiyarova L.M.; Lyakh A.M.. Morphology of the horseshoe spot (HHS) with the cavity has been investigated in details in several species of Planothidium Round et Bukht. that carry out an attached mode of life. On the base of photomicrographs obtained with light and scanning electron microscopy, the model of the HSS longitudinal section was designed and light rays tracing through it has been implemented. It has been shown that HHS is an optical system that may diffuse or focus light, depending on the refractive index of the matter inside the cavity. For the first time HHS functions are revealed in a living diatom organism: diffusion of light over the chloroplast side turned to the substrate. The vertical part of inner convexity generates on the attached valve the heating arc that...
