Descripción: «Research into diatoms commenced with the advent of the light microscope in the early 19th century and progressed to an advanced state in the 1950s. Since then the application of many new techniques, in electron microscopy, biochemistry, molecular biology and sediment dating, to name a few, has provided additional stimulus to the study of these micro-organisms which play a vital role in marine and freshwater ecosystems. Their siliceous cell walls are amongst the best preserved micro-fossils and thus feature greatly in micro-palaeontology and its applied aspects, such as climate interpretation. Ease of culture has also led to considerable use of diatoms in physiological, cell biological and biochemical studies.»
