Bacillariophyceae
Bacillariophyceae (diatoms) Class of unicellular
algae, usually occurring singly, but may be colonial or filamentous. Cell size ranges from 5 to 2000 μm. The cell wall (
frustule) is impregnated with silica and consists of two
valves, one of which overlaps the other like the lid on a box. The frustule is commonly delicately ornamented and pierced by tiny holes (punctae) which may be covered by porous sieve membranes. There are two
orders. The Centrales (centric diatoms) are circular, with
radial symmetry, and are predominantly marine. The Pennales (pennate diatoms) are elliptical, with
bilateral symmetry, and dominate freshwater environments. The frustules have formed an important constituent of deep-sea deposits since the
Cretaceous. The oldest known diatom is usually taken to be
Pyxidicula bollensis from the
Jurassic. See
DIATOMACEOUS EARTH;
DIATOMITE; and
DIATOM OOZE.
