Diatoms in a sentence

Certain araphid species, that is pennate diatoms without a raphe, have been documented as anisogamous and are, therefore, considered to represent a transitional stage between centric and raphid pennate diatoms, diatoms with a raphe.

Ecology A budget of the ocean's silicon cycle citation Regions of high abundance of Diatoms in the ocean Planktonic diatoms in freshwater and marine environments typically exhibit a " boom and bust " (or "bloom and bust") lifestyle.

But scientist Tom Kaye had dismissed the theory, claiming "diatoms" on the cash showed it had been dumped in the river in Spring, not November.

These blooms are comminated by large diatoms, a type of algae that supports many marine animals.

What the bacteria feeding the diatoms may be getting out of the relationship is another question for further research.

Coccolithophores, diatoms, zooplankton, and other planktonic life-forms on much of the ocean’s sunlit surface.

In lower organisms such as diatoms, the strong light manipulation associated with the periodic nanostructure on diatom frustule walls might influence the collection of more light into the photoreceptors for more optimized photosynthetic efficiencies ().

Accordingly, groups like the diatoms may be ranked anywhere from class (usually called Diatomophyceae or Bacillariophyceae) to division (usually called Bacillariophyta), with corresponding changes in the ranks of their subgroups.

Appearance and extinction of planktonic diatoms during the past 18 m.y. in the Pacific and Southern oceans.

A single diatom at first look may not seem to be a cell, but diatoms are eukaryotic organisms with common organelles such as a nucleus, mitochondria, and golgi complex.

Because of this bloom-and-bust cycle, diatoms are believed to play a disproportionately important role in the export of carbon from oceanic surface waters citation (see also the biological pump ).

Diatoms are frequently present as a brown, slippery coating on submerged stones and sticks, and may be seen to "stream" with river current.

Diatoms have been engulfed by dinoflagellates at least three times.

Diatoms inhabit not only oceans, seas, lakes, and streams, but also soil and wetlands.

Diatoms occur in virtually every environment that contains water.

Each ratio essentially tips the odds in favor of either diatoms or more other groups of phytoplankton, such as coccolithophores.

Heterokontophytes (stramenopiles) The photosynthetic pigments present in their chloroplasts give diatoms a greenish-brown color.

However, fossil evidence is scant, and only with the evolution of the diatoms themselves do the heterokonts make a serious impression on the fossil record.

In centric diatoms, the small male gametes have one flagellum while the female gametes are large and non-motile ( oogamous ).

In coastal waters and other places where light reaches the bottom, benthic photosynthesizing diatoms can proliferate.
