diatoms's Usage Examples:

The limestones contain Globigerina and other Foraminifera, the siliceous beds are made of Radiolaria, sponge spicules and diatoms, while the red clay closely resembles the red clay of the deepest parts of the oceans.

Ordinary diatoms and desmids may be mounted on mica, as above described, by putting a portion in a vessel of water and exposing it to sunlight, when they rise to the surface, and may be thus removed comparatively free from dirt or impurity.

Most important are the fine structures of diatoms such as Surirella gemma and Amphipleura pellucida or artificial fine divisions as in a Nobert's grating.

Vegetable plankton in sunlight can reverse this process, assimilating the carbon of the carbonic acid and restoring the oxygen to solution, as was proved by Martin Knudsen and Ostenfeld in the case of diatoms.

It has been found possible to grow pure cultures of various diatoms, and by feeding these to delicate larvae kept in sterilized sea-water, great successes have been attained.

pennate diatoms over flagellates.

The yellow brown stellate colonies are an incredibly beautiful sight and are far better seen freshly collected than cleaned in the manner of diatoms.

Filamentous diatoms may be mounted like ordinary seaweeds, and, as well as all parasitic algae, should whenever possible be allowed to remain attached to a portion of the alga on which they grow, some species being almost always found found parasitical on particular plants.

It is probable that some are carnivorous, either attacking other larvae or subsisting on more minute forms of animal life; but others perhaps feed more exclusively on vegetable matters of a low type, such as diatoms.

In the South, diatoms are favored over flagellates, and in the north, centric diatoms over pennate.

Research projects typically involve interdisciplinary teams where we provide expertise in diatom analysis or the use of isotope ratios in diatom analysis or the use of isotope ratios in diatoms.

These cilia pass on any diatoms and -_„ other minute organism which come within their range of action to the -_-„ capacious oval mouth, which appears as a mere 10 --- deepening of the gutter in the middle line.

The plankton is divided into (a) the Zoo-plankton (such as the minute crustacea and the eggs and larva of fishes and many other marine animals); and (b) the Phyto-plankton, that is, the minute algae, diatoms, peridinians, some flagellate protozoa, spores of alga, etc.
