Witryna10 lut 2024 · This is beautifully illustrated by the calcite plates (stereom) of echinoderms, which exhibit complex, sponge-like morphologies and curved surfaces and yet behave as single crystals. Extraordinarily, the stereom of certain species is highly ordered. A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
