Sida badanayaan algae ah? Species faafin algae

Shiidaa kasta oo biyo ah oo korka ka dhan ah dunida dacaladeeda ku kulmi karaan jirka sida gaar ah, eg in dhirta Halabuurka ay sida algae.

Waa maxay algae

Algae - koox gaar ah ee unicellular ama noolaha multicellular degganaa advantageously ee dhexdhexaad ah aqueous. Tani waa koox si cadaalad badan oo dhirta hoose. Ay Habitat waa sidaas u weyn oo ah in aad meel kasta ka heli kartaa, labada ee badaha iyo badaha, harooyinka, webiyada, hay'adaha kale ee biyaha, carrada qoyan, iyo xataa jilif geed.

Algae - taasi waa sida hal-unuglaha protozoa, iyo deegaanada multicellular. Hargahood oo algae multicellular ka kooban yihiin cellulose, taas oo ku xiran yihiin dhamaadka kasta oo kale.

Nidaamka xididka ma ay samayn. Halkii, algae waxaa ku lifaaqan dusha sare taasi oo ka geedi socodka gaar ah - rhizoids.

Inta hirku - isha ugu muhiimsan ee arrinta organic on Earth. Ku dhowaad dhammaan silsilado cunto bilaabaan iyaga la. Waxaa intaa dheer, iyagu waa il cunto noolaha badan biyaha.

Sidoo kale algae haboon saaridda of Bacriminta, xayawaanka feed, iyo, dabcan, waxaa loo isticmaali karaa isticmaalka bini'aadamka.

asalka ah ee algae

Ilaa hadda ma jiro iswaafiqitaan ku saabsan asalka ah ee algae iyo da'dooda saxda ah ay sabab u tahay xaqiiqada ah in noocan oo kale ah noolaha wakiil kala duwan oo waaweyn. Waxaa intaa dheer, waxa ku hadhay tusaale ahaan hal tijaabooyinka, lafo, oo waa wax aan macquul aheyn si loo ogaado waxa marxaladaha kala duwan ee horumar ah ee noocan ah ee noolaha dhacay.

Bayoolajiga adduunka oo dhan ayaa waxaa ka dhaadhacsan in jirin geedka ee dunida ma leh awooda bogsiinaya la barbar dhigi karaa mid ah inta hirku, sababtoo ah waxaa jira aragti ah oo ku saabsan asalka ah ee nolosha ee badda, taas oo macnaheedu yahay in ay tahay iyaga oo ku kooban Halabuurka noolaha gaar ah.

Si kastaba ha ahaatee, waxaa la rumeysan yahay in algae cagaaran iyo huruud muuqday on Earth ku saabsan 3 billion sano ka hor. ay markii hore ka kacay oo ah qaab hal-unuglaha ka dibna kaliya gumeysiga. Oo waa muuqaalka kore ee noocan ah noolaha keentay in formation of ogsijiin on dhulka jawi iyo lakabka Allena ka, taas oo markii danbe keentay in bixitaanka nolosha. About a billion sano ka hor, waxaa jiray adag algae multicellular.

nooc oo algae

biology Modern yaqaan in ka badan 30 kun oo noocyada of algae. Si kastaba ha ahaatee, waxaad iyaga ku dari kartaa kooxo gaar ah:

1. Euglenophytes ama unicellular. The algae yar.
2. Pirofitovye algae, oo xuub ka kooban tahay cellulose.
3. Diatoms. Waxay ka kooban yihiin unugyada la ah ee loo yaqaan double-duqeeyey.
4. algae Golden. Halkan waxaad kula kulmi kartaa labada unicellular iyo multicellular, laakiin dhan midabka dahabka ama brownish-jaalle ah biyaha saafiga ah.
5. Yellow-cagaaran. Waxa badanaa la isku daray kooxda hore.
6. Green. Waxay waxaa lagu ogaan karaa isha oo qaawan, tusaale ahaan, on jilif la dhigay geedaha.
7. Charophytes. Tani waa algae ee multicellular, kuwaas oo inta badan ay weheliso cagaaran. height ee asliga ah ee u dhaxeysa 2.5 cm ilaa 10 cm.
8. algae Red. Sidaas loo yaqaan sababta oo ah joogitaanka in ay qaab-dhismeedka element gaar ah - fitoeritrina, taas oo midabo kala iyaga oo cas. algae ku nool inta badan biyaha moolka dheer badaha.
9. Kelp. The views ugu kaamil ah. Waxay ku nool yihiin biyo gun dheer iyo awood si ay u abuuraan jiqda, sida badda Sargasso ah. Rhizoids iyaga adag ku lifaaqan dusha sare si ay u aheyn in jeexi yihiin.

faafidda algae ee dabiiciga ah

By habka ah in algae ku kala qaybsan yihiin laba kooxood oo waaweyn: biyaha iyo ku nool on dalka - biyihii ka soo bixiyey.

Taa baddalkeeda, biyaha loo qaybin karaa dhowr qaybood:

1. Plankton. In biyaha ee gobolka a ganaax. Isla mar ahaantaana si buuxda loo habeeyey in sidan nolosha.
2. Benthic. Waxay ku nool yihiin hoose ee berkadood.
3. Periphyton. Live on dhagaxyada quuska baxda leh maadooyinka qoto dheer.
4. Neustonic. Noocan ah algae sabayn xaalad semisubmerged. Mid ka mid ah qayb ka mid waxa uu ku yaalaa korkiisana biyaha, kan kale waa in ay daruuri tahay in la Hawiyaha ah ee biyaha.

Algae dalka ku nool, kala qaybiyaa laba-hoosaadyada:

1. Aerofiton. Algae in koraa walxaha jidhadhka dhulka, waxyaabaha dhacay, jirrid.
2. Algae kordhaya on dusha ciidda.

Waxa intaa dheer in noocyada kuwan, waxaa jira qaar ka mid ah ee ku nool biyaha cusbada leh, baraf ama barafka, iyo sidoo kale hoy u tahay substrate nuuradda ah.

Sidee algae tarmin

Aan la arrinta ugu muhiimsan ee maqaalka ka qabtaan. In dabiiciga ah, algae ku badanayaan saddex siyaabood. Mid kasta oo iyaga ka mid ah waxay leedahay astaamo u gaar ah.

1. Algae vegetatively dhalid. Tani waa hab noocan oo kale ah ee taranka taas oo shakhsi ah qof weyn wuxuu u qaybsan yahay laba ama, tusaale ahaan, laga soocay kelyaha jirka waalidka. Markaas, unugyada cusub u qaybsan yihiin laba ama afar unugyada, taas oo markii danbe ku koraa algae baaluq.
2. dhalmo Asexual. Noocaan wuxuu ka kaas oo unugyada algae ka dhacdaa gudahood kala qeybinta protoplast raacay by ay sii daayo si ka baxsan iyo kala unugyada hooyada.
3. Algae soo saari by kudka, kuwaas oo la soo saaray xubnaha gaarka ah - sporangia.
4. dhalmo Galmada. Ma laga guurayo ee laba unugyada, gametes, taas oo keeni karta in saygoot ah, taasi oo markii dambe uu korayo galay shaqsi cusub ama siinayaa zoospores. Oo saygoot algae kala duwan ka dib markii ay formation u dhaqmaan si ka duwan. In qaar ka mid ah, ay u tagaan muddo nasinta, kaas oo socon karaa ilaa dhowr bilood. qaar kalena A si toos ah Gagaab galay lakabka cusub ama thalli.

Waxa la yaab ah in noocyada kasta oo algae celin kala duwan. Arrintan baarayaa manhajka. Iyo ardayda inta badan maqlaan su'aasha ka macalinka: "Sida loo nooc algae Sharaxaad ka bixi koritaanka algae." waxaa si fudud jawaab, haddii aad ka baran wax ka faahfaahsan.

Marka algae ee asexually dhalid. Noocyada dhalmo asexual

Tani waa fursad ugu fudud. Ama asexually faafin vegetatively algae inta badan kaliya ku hoos jira xaalad wanaagsan iyaga. Taas macnaheedu waxa weeye, markii biyaha ee kaydka leeyahay heerkul ah iyo xaalado gaar ah in loo kordhiyo taranka ah asexual.

Haddii kaydka ama deegaanka dhacaan isbeddel lama filaan ah ee heerkulka, wasakhaysan ama la faafi deggan, haddii ay taasi ku sii soco ilaa algae dhalmo galmada.

dhalmo Asexual loo qaybin karaa dhawr nooc:

1. Algae dhalid vegetatively - waa qayb ka mid ah unugyada daaqsinka.
2. Sporulation. Ama haddii kale algae dhalid by yahay unugyada gaarka ah. unugyada Kuwanu waa loo yaqaan kudka.

Marka algae ee asexually soo saari, waxaa jira hal waalid oo keliya, kaas oo ay dhammaan genomes jira. Laakiin in ay dhacdo isbedel ayaa, waxyaabaha la dhaxlo kala duwanaan karaan xaddi leh.

Inta badan, hal shaqeeyo a soo saari karaa labada asexually iyo vegetatively.

faafinta daaqsinka ah ee algae

dhalmo daaqsinka waa dabeecadda in kiisaska ugu badan ee kelp ah.

In this algae qayb dhalmo habka (fronds) ka kuwa hadda jira soocay, oo aan wax isbedel ah, iyo unugyada cusub sameeyay diyaariyey qayb dhaxalka ka mid ah sanduuqa battariga ee waalidka.

soo saari karaa algae vegetatively unicellular iyo multicellular labadaba. Oo gacanta unicellular qaybiyaa laba, oo kala meel layers multicellular ama deegaanada thalli oo dhan. In habka daaqsinka algae filamentous faafin qaadataa meel by kala filaments ku jajabkii shaqsi ay.

Si kastaba ha ahaatee, ma dhammaan algae ka amarka ka mid ah wakiilada gumeysiga vegetatively soo saari karaa, iyo sidoo kale in ay la socdaan unicellular habka faafinta daaqsinka jiri karaan iyo habka galmada.

Brown algae, sida kor ku xusan, waxa sidan u tarmin, taasi oo ka cidla ah laamaha khaaska ah. In si la mid ah in ay soo saari dhan cayn kasta oo Sargassum Badda Sargasso ah.

dhalmo khilaafaadka

Waxa intaa dheer in algae ee faafinta daaqsinka ku soo saari by kudka. Tani waa dacawo gaar ah oo taranka asexual.

Kudka loo sameeyay in xubnaha gaarka ah, ama wax-u zoosporangia sporangia. Haddii kudka sayrtay in ay Gagaab, ka dibna aasaasay qof is-qof weyn oo cusub.

kudka Motile la flagella awood u dhaqdhaqaaqa, loo yaqaan zoospores.

kudka asexual kala duwanaansho la oran karo waa, tusaale ahaan algae sida ulothrix. In xaaladaha wanaagsan, waayo nolosheeda ka strands waalidka jira waxaa loo kala jajabkii ay, kuwaas oo ka kooban kudka ah. Waxay dabaalan ee gobolka free, ka dibna, isagoo ku lifaaqan walxaha quuska, bilaabaan in ay si firfircoon u kala qaybin iyo foomka algae a thread cusub. Waa in la ogaadaa in noocan ah algae isku mar soo saari karaa labada asexually iyo galmada.

Waxaa la arkay in ay suurto gal tahay in ay kicin formation of kudka ee noocyada qaar ka mid ah algae thread, waayo, taasu dhici doona koror ah carbon dioxide ee deegaanka.

Shaqada faafin ah asexual kiiskan ayaa sporophytes gaar ah loo yaqaan, sida sameynta kudka.

dhalmo galmada

Waxa intaa dheer in hababka kor ku xusan algae saari galmada. Waxaa lagu gartaa, dhammaan ayuu ka sarreeyaa, unugyada labka iyo dheddiga, ie isuga laba unugyada - gametes. Intaas ka dib, saygoot ah waxaa la aasaasay taas oo markii danbe uu noqonayaa progenitor ee u shaqeeyo cusub.

Waayo, algae, waxaa jira dhawr dariiqo faafin galmada:

1. Isogamy - waxa uu tusinayaa isuga ka mid ah laba qaab-dhismeedka loo siman yahay oo cabbirkooda iyo gametes.
2. Heterogamy. Sidaas wac isuga laba gametes, kuwaas oo mid ka mid ka badan kan kale. Oo wax alla wixii ka weyn ee size yihiin inta badan dumar ah.
3. Oogamy. In dhalmo habkan ku milmaan unugyada aan firfircooneyn la gamete lab dhaddig dhaqaajin karo.
4. Conjugation. Under fikradda waxa ay tilmaamaysaa, noocan ah ee taranka, taas oo la xidhiidha laba ka mid ah unugyada daaqsinka, wax garad flagella.

algae heer hoose ah, kartida gaar ah la mid ah sida dhalmo galmo iyo asexual. In shaqo ugu horumaray waxaa la sameeyaa by shakhsiyaadka loo yaqaan gametophytes, ie la xirrira gametes.

Tusaalooyinka algae taranta

Tusaale ka mid ah faafinta daaqsinka ah ee algae uma shaqayn karo sidii fucus. In ugu weyn waxaa la aasaasay thallus dheeraad ah oo la mid ah in fronds qaab-dhismeedka, taas oo markii danbe ku siin kor u shaqeeyo cusub.

dhalmo Asexual, in uu yahay, kala qeybinta laba unugyada, oo laga dheehan karo in Euglena.

Chlamydomonas - dhufashada alga this taas oo dhacda labada galmada iyo asexually by yahay ee kudka (zoospores) isagoo flagella.

Tusaale kale oo dhalmo galmada shaqayn karo algae brown sida Laminaria. In noocyada this waxaa jira saddex hab oo faafin galmada, sida isogamy, getorogamiya, oogamy.

Chlorella - alga cagaaran cqaadir. Waxaa celin asexually oo keliya macnaha of kudka.

algae Red (whelk) nooc laba siyaabood, mid ka mid ah taas oo ah galmada. Muuqaalka kala waxaa ka mid ah waa formation of gametes lab oo aan flagella. Xaaladdan oo kale, gametes dumarka algae, iyo rag wareejiyo iyaga by hab socodka.

Taasoo la micno ah ee algae ee dabiiciga ah

Algae - ugu badan oo muhiim u ah noolaha photosynthetic caalamka oo dhan ayaa. Waxay faafinta si ballaaran in ay laga heli karaa oo keliya ma aha ee badaha, badaha, Wabiyaal, harooyinka, laakiin sidoo kale in meydadka yar oo biyo ah, oo ay ku jiraan macmal ah iyo xitaa puddles. Waxay waxaa lagu arki karaa dhibco yar meelo godgodan oo ku saabsan dusha sare ee shiidaa kasta oo biyo ah. Taasoo la micno ah inta hirku dabiici sare.

ka xaqiiqda ah in ay dhaadheer qadar ku filan badan oo oxygen reebo, waxay u adeegaan sida Habitat for xoolo badan biyaha, ka qayb formation of dihnayd. algae badan oo la cuno, iyo sidoo kale u adeegaan sida isha ugu muhiimsan ee wax soo saarka qaybaha cuntada gaarka ah. Waxaa sidoo kale loo isticmaalaa diyaarinta daawooyinka kala duwan oo la isku qurxiyo.

Algae - waa mid gaar ah ee ay ka kooban iyo habka of noolaha afgembi. waxay isu geeyo dhowr nooc oo ah taranka, ama halkii, galmada, asexual iyo daaqsinka. Waxay u dhawdahay inay iyaga ka dhigaa inay dhiman. Waxaa intaa dheer, arrintan waa mid aad u madadaalo, ma aha mar macalimiinta biology yaab guud ahaan dalka sameynayaan ardayda in ay ka jawaabaan su'aasha ah: ". Sida loo nooc algae Sharaxaad ka bixi koritaanka algae"
