ROLL OF CHEMISTRY FOR DIATOM SHAPE DETERMINE

Diatoms are single-celled organisms which secrete intricate skeletons. These may be elongate with a bilateral plane of symmetry or they may be round and radially symmetrical. Diatoms (class Bacillariophyta) are a type of mainly aquatic photosynthetic algae. Similar to many other algae they can live as unicellular organisms colonial or filamentous. Unlike most algae though they have a solid shells made of silica. Because of such shells diatoms have major economic importance in industry while also having a major role in biological and chemical processes.
