diatoms ka kya matlab hota hai


डायटोम्स

Noun:

डायटम,



diatoms शब्द के हिंदी अर्थ का उदाहरण:

प्रमुख फोटोसिंथेटिक प्रोटिस्ट् हैं डायटम, डिनोफ्लाजलेट, युगलिना आदि।

डायटम एक तरह के एककोशिकीय समुद्री शैवाल होते हैं।

प्रमुख खाद्य सामग्री के रूप में सूक्ष्म उत्प्लावाक, डायटम (diatom), पादप समभोजी (holophytes) तथा डाइनोफ्लैजिलेट्स (dinoflagellates) ही प्रयुक्त होते हैं, क्योंकि ये अत्यधिक संख्या में पाए जाते हैं।

इसके विपरीत, कोपलैंड का कार्यकाल ऐसे डायटम, हरी शैवाल और कवक के रूप में केन्द्रक यूकेरियोट्स शामिल थे।

एक दूसरा उदाहरण डायटम (Diatoms) का है।

अन्य प्रोटोज़ोआ और डायटम (diatoms) इसके भोजन हैं, जिन्हें यह कवच छिद्र से निकले बाह्य जीवद्रव्य स्तर से उत्पन्न, लंबे, पतले, शाखावत् और उलझे पादाभ द्वारा पकड़ कर लगभग कवच से बाहर ही पचा लेता है।

ऐसा इसलिए है क्यूंकि mesopelagic क्षेत्र (mesopelagic zone) (लगभग 200 से 1000 मीटर की गहराई तक) में पोषकों का गिरता हुआ स्तर डायटम (diatom) के विकास में भादक होता है और छोटे phytoplankton (phytoplankton) के हक़ में होता है जो की कार्बन के biological pump (biological pump) स हैं।

नेरेटिक डायटम अधिकाधिक सुप्त बीजाणु (resting spores) उत्पन्न करते हैं।

(ख) सूक्ष्म वनस्पतिसमूह (microflora) जैसे काई या शैवाल (algae), डायटम (diatom), कवक, (fungi) ऐक्टिनोमाइसीज (actinomyces) आदि,।

विपुल पादप पोषकों के उपयोग के लिए समुद्र की सतह से ५० मीटर की गहराई तक डायटम, डाइनाफ्लैजिलेट् तथा दूसरे सूक्ष्म पादपों ने अपना निष्क्रिय प्लवमान अस्तित्व बना लिया है।

जिन स्पीशीज़ में बृहद छिद्र होता है उनके कवच के जीवद्रव्य (protoplasm) में जीवाणु, कशाभिक प्रोटोज़ोआ, शैवाल के बीजाणु (spores of algae), डायटम (diatoms) तथा जैविक अपरद (detritus) पाए जाते हैं।

diatoms's Usage Examples:

The polypide consists of a "lophophore" bearing a series of ciliated tentacles by which Diatoms and other microscopic bodies are collected as food, of a U-shaped alimentary canal, and of a central nervous system.


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.


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.


This is really the case, for all observations show that the Antarctic and Arctic ice-bound seas are enormously rich in diatom life when compared with temperate and tropical regions: the great Antarctic zone of sea-bottom deposit, in which the skeletons of diatoms predominate, covers some ten millions of square miles.


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.


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.


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.


+h,r, 1)s~,~s-s Diatoms and Desmids, according to recent researches, the thickenings on the outer walls of the cells are due to the passage of protoplasm from the interior of the cell to the outside, through pores which are found perforating the wall on all sides.


In some cases both the nucleus and the chromatophores may be carried along in the rotating stream, but in others, such as T.Titeila, the chloroplasts may remain motionless iii a non-motile layer of the cytoplasm in direct contact with the cell wall.i Desmids, Diatoms and Oscillaria show creeping movements probably due to the secretion of slime by the cells; the swarmspores and plasmodium of the Myxomycetes exhibit amoehoid movements; and the motile spores of Fungi and Algae, the spermatozoids of mosses, ferns, 'c., move by means of delicate prolongations, cilia or flagella cf the protoplast.


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.
