Pharmacognostic standardization; physico-and phytochemical evaluation of the roots of Amaranthus spinosus was carried out, to determine its macro-and microscopical characters, and also some of its quantitative standards. Microscopical studies were done by using the trinocular microscope. Chrysophyta (golden algae, golden-brown algae) A division of predominantly unicellular algae (sometimes alternatively regarded as protozoa, class Phytomastigophora) in which the chloroplasts contain large amounts of the pigment fucoxanthin, giving the algae their brown are flagellated, having one flagellum of the tinsel type and a second flagellum of the whiplash type, which .
Introduction to the Chrysophyta Golden Algae. Chrysophytes, or golden algae, are common microscopic chromists in fresh water. Some species are colorless, but the vast majority are photosynthetic. As such, they are particularly important in lakes, where they may be the primary source of food for zooplankton. Alfred William Bennett (24 June – 23 January ) was a British botanist and publisher. He was best known for his work on the flora of the Swiss Alps, cryptogams, and the Polygalaceae or Milkwort plant family, as well as his years in the publishing mater: University College London.

Pp Pelomyxa is a genus of giant flagellar amoeboids, usually μm but occasionally up to 5 mm in length, found in anaerobic or microaerobic bottom sediments of stagnant freshwater ponds or slow-moving streams.. The genus was created by R. Greeff, in , with Pelomyxa palustris as its type species. In the decades following the erection of Pelomyxa, researchers assigned numerous new Class: Archamoebae.

Each genus is provided with its author and the source publication. This is followed by a class-order family classification, the type species, basionym (if applica ble) and nomenclatural synonyms. The number of recognized species is indicated numerically (e.g.
four species), but their names are not provided. A microscopical study of four chrysophyte species, Synura petersenii, S.
uvella, MaJJomonas papillosa and M. cratis, with special reference to morphology, production and composition of scales. Ph.D. thesis, University of Birmingham, by: The dichotomy between high microbial abundance (HMA) and low microbial abundance (LMA) sponges has been long recognized.
In the present study, 56 sponge species from three geographic regions (greater Caribbean, Mediterranean, Red Sea) were investigated by transmission electron microscopy for the presence of microorganisms in the mesohyl by: This paper deals with three species of Mallomonopsis, twenty-one species and one variety of Mallomonas, four species and three formae of Synura, one species of Chrysosphaerella, two species.

Sparicotyle chrysophrii is a species of monogenean, parasitic on the gills of a marine belongs to the family type-host is the gilt-head seabream (Sparus aurata).The species was described by Van Beneden & Hesse in under the name Microcotyle chrysophrii and transferred to the genus Sparicotyle by Mamaev in Its morphology has been described in from Class: Monogenea.
Different single- and multi-species communities of chrysophytes were used to determine a species-specific response to the predators and the effect of chrysophyte diversity. A Microscopical Study of Exotic Animal Hairs: Part 2 Kristen D. Wiley Brookfield Zoo, Brookfield, Illinois, has been exceptionally cooperative and generous with the collection of hairs from an array of animals at their zoo.
Although many are unicellular and free swimming, some chrysophytes, like the dynobryon above, join together and form colonies, like the filamentous algae colony to the right.
There are over described species of Chrysophytes, and, because there are so many species, there is. But in many species, e.g., in colorless species, organic compounds can be taken up from the water or by phagocytosis. Life history includes mitotic divisions and encystment.
Abstract. The chrysophytes (more than 1, described species) are unicellular or colonial algae characterized by heterokont flagella and chloroplasts with chlorophyll a and c, and by their endogenous silicified occur mainly as phytoplankton in temperate freshwaters, and their distribution is ecologically determined, mainly by temperature and pH.

Jap. Phycol. – Google Scholar Takahashi, E., K. Cited by: But for an introduction to the subject, this book may appeal to the hopeful diatomist. The late Robert McLaughlin was a redoubtable microscopist and published extensively on diatoms, also at the scientific level.
This book, admirably edited by Delly and Gill, presents a sort of aggregate of “everything he picked up” in the course of many years. In the current study, however, the growth of the two algal species was inhibited to some extent at μmol photons m −2 s −1.

Nygaard () was the first to apply electron microscopy (EM) to phytoplankton samples from Greenland, but his investigation revealed only one Paraphysomonas species (P.
vestita) and no Spiniferomonas species. Other poorly represented chrysophyte genera included Chrysosphaerella (neither of the common species C. longispina or C. brevispina was observed), and only one species. Cite this article.
