Značilnost diatomej je trdno
ogrodje, zgrajeno iz kremenjaka.
Zato so dobile ime kremenaste
alge. Miniaturne umetnine narave
z raznolikimi ornamenti pri nekaterih
vrstah spominjajo na okrogel
čipkast prtiček, pri drugih na domiselno
okrašeno šatuljo — škatlico s
pokrovom. To sta dve veliki skupini
diatomej.
The characteristic of diatoms is a
firm skeleton — frustules composed
of silica. Highly ornamented miniature
nature works of art in some species
resembles a round lace, in others
a fancy decorated case with a cover,
thus forming two major groups
recognized as centric and pennate
diatoms, respectively.
