Qaab dhismeedka Spirogyra - wakiil caadiga ah ee algae waaxda Cagaaran

Spirogyra loola jeedaa Waaxda algae cagaaran. Its jirka waa qaab thallus filamentous, oo ka kooban unugyada shaqsi oo aanu u sameeyaan unugyada iyo xubnaha. Waa muujinta a caan ku dhamaan xubnaha kooxda ka mid ah dhirta hoose. Waayo, lifaaqaaya in ay salka, sida in algae oo dhan, in Spirogyra leeyihiin rhizoids. Iyadoo qaababka kuwan filamentous thallus lifaaqan substrate ah. Rhizoids sidoo kale raasamaal unugyada iyo ma sameeyaan unugyada.

Spirogyra ka tirsan waaxda algae Green go'aamiyo jiritaanka chloroplasts in unugyada jirka geedka. dhismayaasha metalaysa hal nooc oo plastids. Sababo la xiriira joogitaanka chloroplasts Algae, sida dhirta oo dhan, ay awoodaan si ay u fuliyaan nidaamka of photosynthesis - carbohydrates is-sameynta looga baahan yahay koritaanka iyo horumarka.

Qaab dhismeedka unugyada Spirogyra

Tani waxay ka wakiil ah algae yaryar oo qoyan waa shaqeeyo multicellular. Qaab dhismeedka Spirogyra (tiradaasi kor ku xusan ayaa muujinaya qaab dhismeedka aasaasiga ah) waxaa wakiil u ah qaab-dhismeedka filamentous dheer. Chloroplasts ee algae leeyihiin qaab strips, kuwaas oo spirally duudduubay. Habkaani, oo ku qeexan magaca noolaha ku tilmaamay. Unugyada ayaa sidoo kale ifafaalaha in ay leeyihiin qaab cylindrical. Waxay ku xiran yihiin by daloolada in xuubka ka, iyo iyada oo loo marayo taas oo lagu sameeyaa habka shiid.

Sida unugyada dhirta oo dhan, wax badan oo ka mashquulin vacuoles oo wakiil ka ah taangiyada iyo biyo, iyo nafaqooyin kala diri buuxiyey. Shell cufay cellulose carbohydrate, wuxuuna iyaga siiyey xoog iyo rigidity.

Alga Spirogyra, sida dhirta oo dhan, waa shaqeeyo a eukaryotic. Taas macnaheedu waxa weeye in unugyada ay ka kooban xuduntii ah. organelle waa wax hidde ku jira taagoo DNA ah.

degaanka

Alga Spirogyra in intooda badan waa degganayn hay'adaha biyaha saafiga ah ee biyaha taagan. Laakiin iyadu way la kulmay iyo badaha. Her thread, texeen tiro badan, sida dhogor oo cagaaran, sabayn on dusha sare.

cuntada

Qaab dhismeedka Spirogyra go'aamiso ay yihiin nooca iyo awood, sababta oo ah unugyada ka kooban chloroplasts algae cagaaran plastids in ay yihiin awood u photosynthesis. Its nuxurka been in formation of walxaha organic ka imanba ay sabab u tahay shucaaca qoraxda. Noocan ah oo daaqaysa yeedhay autotrophic.

The algae glucose keentay waxaa laga dalbadaa in ay geedi socodka muhiim ah iyo koritaanka u shaqeeyo. oxygen sii daayo A waxaa loo baahan yahay by noolaha oo dhan, waayo, Neefta - xaalad lagama maarmaanka u ah jiritaanka caalamka. Isha of walxaha lagama maarmaanka u ah photosynthesis, kuwaas oo, biyaha iyo carbon dioxide, si toos ah waa ay Habitat.

dhalmo

Waayo, alga this cagaaran waa dega faafinta daaqsinka qaybo ka mid ah thallus ah. strands badan oo waa jajaban yihiin qaybo, mid kasta oo taas oo ku siinayaa asaasmeen shaqeeyo cusub. Taasina waxay keentaa in xooga iyo wax soo saarka sare ee geedi socodka. Si kastaba ha ahaatee, qaab dhismeedka waxay suuro gelineysaa in Spirogyra iyo habka galmada. Wuxuu qaadataa foomka of conjugation. Sayidka filaments algae isku maran yihiin, waxbarashada gaarka ah baxdo therebetween - channel copulatory. Sida laga soo xigtay, waxa uu ka kooban yahay gudaha ka mid ah gacanta ku jiraan waxyaabaha hidaha qubanayo in kale. Natiijadu waxay tahay formation of a shaabadeeyey - zygospore. In gobolka this, inta hirku keenaya xaaladaha loo kasin, iyo guga waxaa ka mid ah ku koraa soo xareeyo dhallinyarada filamentous.

Geedi socodka galmada ka dhigaa suurto gal ah ee guryaha cusub ee jirka, taas oo muhiim u ah qabsashada dhirta si ay u bedelaan xaaladaha deegaanka.

Qiimaha in la lafaguro iyo nolosha aadanaha

Qaab dhismeedka Spirogyra waxaa shayga ugu muhiimsan ee shaybaarka ka dhigaa, sababtoo ah waxa ay leedahay unugyada a weyn in ay gaaraan ugu 0.01 mm dhexroor. algae Tani foomamka jiqda cufan kaydkan badan. dabdhaliyayaasha Tani waa awoodaa inuu qoondeeyo qadar ku filan badan oo ogsijiin. Laakiin hantida tani waa qiimaha xun, sida ay keenaysaa in waterlogging geedi socodka ee bololka iyo algal blooms. Sidaas darteed, xoolo badan si fudud u dhiman karo. Dhab ahaantii erayada of song carruurta "la nuugo meeshii bannaanayd brown of balli dhoobada qadiimiga ah" waxaa u huray in ay kooxahaasi filamentous cagaaran Spirogyra. Si kastaba ha ahaatee, ay sabab u tahay in la soo waaqsado tiro badan oo ah nolosha biyaha, iyo dabdhaliyayaasha, oo waa inay awoodaan inay sameeyaan, dhowr jeer ka badan tilmaamayaasha la mid ah dhirta kuwa dhulkuna.

Spirogyra waa wakiil caadiga ah ee kooxda dhirta hoose - kuwaas oo, Waaxda algae cagaaran. Waxay u adeegtaa qayb muhiim ah oo la lafaguro ee dhammaan biyaha saafiga ah, il ee arrinta organic iyo oksijiin.
