Tilmaamo Dhismayaasha iyo qaab-dhismeedka Chlamydomonas

Chlamydomonas - a hal-unuglaha shaqeeyo, astaanta ah taas oo ah joogitaanka laba flagella Boodaynin. Waa panulirus ah algae oo qoyan oo aan ku nool biyaha fadhiya iyo ciidda qoyan, iyo sidoo kale in biyo nadiif ah ama badda. Dhismaha Chlamydomonas uu leeyahay tiro ka mid ah qaababka. Ka mid ah channels ra'iyi kuwaas oo ah kuwa waxaa lagu firfircoonaan by gaadhista toos ah oo ay iftiinka, iyo indhaha photosensitive cas iyo nidaam sharciyeed oo adag.

Chlamydomonas: warbixin guud

By nooc oo cunto ah badi noocyada ay yihiin phototrophic waajibiyo. Laakiin qaar ka mid ah ay yihiin heterotrophs facultative, kaas oo u koraan karaa in mugdi ah, iyadoo la isticmaalayo sida ilo carbon copolymer. In ay fataahadda waa mobile algae unicellular, sida caadiga ah gadood. derbiga unug ka kooban yahay glycoprotein ah. Chlamydomonas saari labada galmada iyo asexually.

Waxaa jira qiyaastii 150 noocyada. Chlamydomonas si firfircoon proliferates jawi qoyan, iyo sidoo kale in xeryahooda ammonium biyo-hodanka ah. Features of qaab-dhismeedka Chlamydomonas ka mid ah joogitaanka pigments. Dhoobo cagaaran midabka biyaha ee biyaha fadhiya sabab u ah joogitaanka kun oo sheyga flagellated. Midabka cas Bright ka mid ah noocyada kordhinaya xayd degaanada in midabka cas ama casaan. Qaar ka mid ah noocyada waxaa laga helaa meelaha ugu lama filaan ah, sida biyaha badda cusbada.

Dhismaha Chlamydomonas

In dhabarta afka ilmo-galeenka waa laba flagella, ka badar asalka ku yaalla cytoplasm qaadan asalkiisa. saldhigyadoodii contractile vacuole. Dhismaha unugyada Chlamydomonas soo jeedinaya joogitaanka chloroplast koob-qaabeeya a, halkaas oo waa bu'da unugga. Waxaa la aasaasay ka soo saarka istaarijka photosynthesis iyo protein, hareereysan badar istaarijka. Albabka galay kaalinta a joogo hore ee chloroplast ah. Waxay ka kooban tahay laba ama saddex, ka badan ama ka yar saf isku midka ah dhibcahaa baruurta linearly diyaarin.

Features of qaab-dhismeedka

In ay marxalad daaqsinka u shaqeeyo leedahay qaab aad u fudud. Its size kala duwan 0.02 mm. cell kasta wuxuu leeyahay goobaabin, ellipsoidal, cylindrical ama qaab pear. Waxay u janjeera in ay dhuuban dhamaadka hore. Qaab dhismeedka gacanta Chlamydomonas ka kooban yahay derbi khafiif dibadda ah, laba flagella, iyo sidoo kale laba vacuoles contractile mas'uul ka ah neefsashada oo Digo. Midabka The orange-cas ama eyelet (dhaleeceynta) kaydiyaa derbiga unug ka sii dhumuc weyn, oo u qabata shaqo ee heer hoose ah, sida waa mid aad u xasaasi ah oo ay iftiinka. noocyada qaar ka mid ah waxaa laga yaabaa in ay goobjoog ka ahaayeen laba ama saddex dhibco isha. chloroplast duuban sare, oo ku yaalla gudaha asaasiga ah waxaa ku yaalla qaybta ubalaadhan oo jidhka ah in cytoplasm ah.

Sidee dhismeedka gacanta taranka asexual?

Qaab dhismeedka Chlamydomonas Oo Qaliin qaar ka mid ah isbedel lagu jiro kala qeybinta unugyada. dhalmo Asexual dhacdaa sida soo socota: abuurista xaalad faa'ideynaayo sameeyay cell zoospores sidaas noqdo go'an, Qarinaysaan flagella ama tuuraa sidoo kale baaba'aan vacuoles contractile protoplast longitudinally qaybiyay laba qaybood, mid kasta oo, markeeda, waxaa loo qaybiyaa 2 qaybood. Sidaas darteed, unugyada kasta soo saartaa 2 ilaa 16 Me qaababka la mid ah. Tartiib tartiib, shakhsiyaadka dhalinyarada ah ka muuqan oo dhan dhismeedka caan ku algae cagaaran: flagella, vacuoles, iyo wixii la mid ah. Mid kasta oo iyaga ka mid ah uu yeesho galay warshad cusub. geedi-soociddiisa Tan waxaa loo soo noqnoqda 24 saac kasta. Sayidka by dhamaadka isbuucaan ka mid warshad soo saarta hooyada oo ku saabsan laba milyan oo qof oo la sameeyay.

Features faafin galmada

Inta lagu guda jiro dhalmo galmada cell protoplast qeybin 16, 32 ama xitaa 64 flagellates gametes in ay noqon kartaa Qaxwo ama maxaabiista derbiga unug. unugyada Sex fiyuuska Wehel si ay u sameeyaan saygoot ah. Sidaas darteed, waxaa la soo koobay, isaga baxday flagella, la xirrira derbi ku wareegsan qaro weyn cytoplasm iyo quustay inay hoose ee kaydka u ah horumarinta dheeraad ah. In foomkan waa mid deggan si heer kulka iyo noolaan doonaa xitaa haddii kaydka qalalo. Zoospores iyo gametes morphologically la mid yihiin. Waxay ku kala duwan kaliya ee size iyo dhaqanka. Farqiga Tani baxdo sabab u ah unugyada badan oo gacanta hooyada inta lagu guda jiro formation of gametes. Sidaas darteed, shakhsiyaad yar lumiyaan awoodda ay is-nolol.
