Occurrence and structure of intranuclear crystals in Chara cells

Abstract:
New intranuclear crystals were described in cells of Chara vulgaris. These were needle-like structures extending for about 8 μ in length and 350mμ×110mμ in transverse dimensions. Each crystal was composed of hexagonally-packed, tubular structures about 200-240 Å in diameter, apparently running parallel to each other along the longitudinal axis. Such crystals appeared to pass through one of the several nucleoli in each nucleus. It is suggested that the crystals are proteins having a storage function, which are synthesised in the nucleolus.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
