Kristiansen, J. and Preisig, H. The cell of a desmid is often divided into two symmetrical compartments separated by a narrow bridge or isthmus, wherein the spherical nucleus is located. Many desmids also secrete translucent, gelatinous mucilage from pores in the cell wall that acts a protecting agent. Most biologists believe that the chrysophytes obtained their ability to photosynthesize from an endosymbiotic relationship with fucoxanthin-containing cyanobacteria. Peniaceae. The active, "feathered" (with mastigonemes) flagellum is oriented toward the moving direction. Sandgren, C.D., J.P. Smol, and J. Kristiansen [Eds.]. Originally they were taken to include all such forms of the diatoms and multicellular brown algae, but since then they have been divided into several different groups (e.g., Haptophyceae,[5] Synurophyceae) based on pigmentation and cell structure. This option is incorrect. 11%.

This class of algae comprise about 33 different genera and 1200 different species. Hope you found this question and answer to be good. The Chrysophyceae should not be confused with the Chrysophyta, which is a more ambiguous taxon. Golden algae (diatoms) - xanthophyll pigments give them a yellowish coloration (diatoms) Green algae - precursers of plants (Volvox, Spirogyra, desmids) In addition, we also have a NON-algal organism called Anaebena which is actually a kind of photosynthetic bacterium in the group of cyanobacteria. An important characteristic used to identify members of the class Chrysophyceae is the presence of a siliceous cyst that is formed endogenously. These form carbohydrates for energy storage.

Flagellated male gametes are present in all the three of which one of the following sets? Most motile diatoms are unicellular, are characteristically benthic, and move by means of a raphe (mucilage extruded through a long, narrow opening in the cell wall). Desmids are sometimes treated as a family (Desmidiaceae) of the order Zygnematales. Many of these algae are also encased in a silica cyst ornamentation known as statocyst or statospore.

Desmids commonly reproduce by asexual fission, however, in adverse conditions, Desmidiales may reproduce sexually, through a process of conjugation,[11] which are also found among the closely related Zygnematales. [4] A fifth family Mesotaeniaceae was formerly included in the Desmidiales,[13] but analysis of cell wall structure and DNA sequences show that the group is more closely related to the Zygnemataceae, and so is now placed together with that family in the order Zygnematales. Van den Hoek, C., D. G. Mann, & H. M. Jahns, 1995. http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/wimsmall/algdr.html, Proceedings of the Royal Society -Biological Minerals Formed from Strontium and Barium Sulphates. In the inner layer of the wall the pore is a simple canal, but in the outer, except in Closterium, the canal is surrounded by a specially differentiated cylindrical zone, not composed of cellulose, through which the canal passes. It is possible membership will be revised further as more species are studied in detail. The cell-wall, of two halves (termed semicells), which, in a few species of Closterium and Penium, are of more than one piece, has two distinct layers, the inner composed mainly of cellulose, the outer is stronger and thicker, often furnished with spines, granules, warts et cetera.

Scotlands most fascinating types of green algae are desmids and stoneworts, and conserving the habitats of rare stoneworts is a priority. Chromulinales Desmids, a family of green algae characteristic of acidic habitats, can move by extruding small bursts of pectin through the cell wall. At the inner surface of the wall they terminate in lens- or button-shaped swellings, while from the outer end of the pore-organ there sometimes arise delicate radiating or club-shaped masses of mucilage through which the canal passes and which appear to be more or less permanent in character. Many of the chrysophyta precursor fossils entirely lacked any type of photosynthesis-capable pigment. Most of them are photosynthetic. The Questions and Answers of Give example of chrysophytes?

Similar, in a sense, to snowflakes, it is difficult to find two identical desmids because they exist in a tremendous variety of shapes and sizes. These pores are either, as in Micrasterias, uniformly distributed across the cell-wall but always appear to be absent in the region of the isthmus, or, in highly ornamented forms, as many genera of Cosmarium, grouped symmetrically around the bases of the spines, warts and so on with which the cell is provided. Aug 4, 2015 - Desmids (Green Algae) - Micrasterias rotata Desmids are microscopic fresh water algae with attractive forms. They are now usually restricted to a core group of closely related forms, distinguished primarily by the structure of the flagella in motile cells, also treated as an order Chromulinales. Scotlands most fascinating types of green algae are desmids and stoneworts, and conserving the habitats of rare stoneworts is a priority. Called statospore, stomatocyst or statocyst, this structure is usually globose and contains a single pore. This option is correct. Many desmids are symmetrical in more than one plane. 85) Write few examples of Kelps: B. Eubacteria are also called false bacteria.
