Diatoms

Ulwandle namanzi acocekileyo, kwakunye omanzi bekhula diatoms. Brown ezi zityalo ukunika zombala photosynthesis emthubi-brown. Le peculiarity yezi ulwelwe kukuba iiseli zabo ayakhuselwa iqokobhe ngaphandle nzima - frustuloy (iqokobhe). Izityalo kukhule kokubini ngabanye kunye nakwiindawo eziphakathi ezingamathanga. Iphila izinto becala komgquba bume.

Diatoms babe isakhiwo ekhethekileyo. Ezi seli luqulathe beziya amabini (epiteki kunye hypotheca). nodonga Frustuly exhotyiswe pores apho i utshintshiselwano izinto kunye nokusingqongileyo. Ezinye izityalo ezo zibe yokuvula slot emile ecaleni iqokobhe nga usebenzisa yencindi ukuhamba ecaleni zeendawana.

Ezizalana ulwelwe, njengazo zonke izinto eziphilayo, iyantlukwano. Ukufumana inxalenye yeqokobhe lomzali, umncedisi we-iseli iqalisa ukukhula ngenkuthalo. Nangona kunjalo, lo frustula omdala ithumba iziphelo yabo entsha. Ekubeni iiseli inwebu eziqinileyo phantse angakwazi ukukhula elandelayo ulwelwe kwinkqubo yokuzala lincipha ngokuphawulekayo. Nangona kunjalo, ngenxa auxospore ukwakhiwa, okubhalwe iiseli zezityalo uyakwazi ukufumana phandle yeqokobhe kwaye uqale ukwahlukana entsha. Ngelo xesha linye isizukulwana aselula diatoms iza kuba nkulu kakhulu kunaleyo yangaphambili.

Iintlobo ze ulwelwe:

• Melozira. Olu hlobo ehlala emanzini amtyuba emanzini ahlaziyekileyo. amandla kubonelelwa ngokusebenzisa inkqubo yefotosinthsis. Ezi diatoms zisetyenziswa ikakhulu uhlalutyo amanzi eziphilayo, ukucaza iqondo ezinokosulela ichibi.
• Gomfonema. Izityalo ezi zilwanyana lukhula kumanzi acocekileyo. Baya uzijonga ulwelwe okanye ezinye izinto ezahlukahlukeneyo emazantsi nokwakha ngamathanga zabo. Olu hlobo nabalulamileyo kwiimeko iqondo lobushushu. Kuba molluscs, la lisiza ziphatheka bondle ezixabisekileyo.
• Plevrosigma. Ezi zityalo zifumaneka amanzi amtyuba zaselwandle apho kuba kukutya iintlanzi abatsha.
• Sinedra. Diatoms eli qela zezi zityalo olunye-elilodwa. Bona ukudala amathanga efana imilo yabo iinyanda fan. Njengenxalenye "inkosi" yayo bakhetha ulwelwe eluhlaza okanye ezincinane. yokuhlala Sinedry - umlambo ngokucotha ugeleza emi amanzi. Olu hlobo asifanele nokondliwa iintlanzi.
• Navicula. Ezi ulwelwe zingafunyanwa yonke. Baya kuvela emazantsi anodaka angenawo, ematyeni emanzi kunye nomhlaba.
• Pinnulyariya. Diatoms yale hlobo zifumaneka kwiindawo ezinodaka of amachibi kunye namasimi erayisi. Ngenxa yokuthiya kwayo phezulu ukuya utshintsho ubushushu bahlala phantse zonke iimbombo kulo mhlaba. Leaf iiseli isityalo alondolozwe kakuhle kakhulu eludakeni. Ngenxa kweli phawu abantu pinnulyarii abe nempumelelo kakhulu.

Ingca yolwandle kelp kukhula kwiMpuma Ekude kunye nonxweme beelwandle wasentla. ubude babo babe ukusuka kangangeemitha ezi-2 ukuya ku-6, ububanzi - 35 cm. isityalo ukhetha ezilulwalwa ukuze baziphilise. Ngokuxhomekeke kwiimeko sezulu yokuba ukuba ubomi obuphilwayo ayathanda phakathi kweminyaka emi-2 no-4.

Ekhuthazwa Imbewu kelp leyo akhiwa inkunzi prothallia nemazi. Zakha gametes (iiseli intsholongwane). Emva ukuchumisa iqanda luphumba abaselula kelp sporonosyaschaya.

Kelp sisetyenziswa ngokubanzi amayeza, ukupheka kunye izithambiso.

Thallus kelp ethathwa ukutya. Izityalo bafumana salads ezinkulu, isuphu, iintlobo kunye neelekese. Xa cosmetology esetyenzisiweyo oyile kunye nezithako lisiza. Ukubakho iikhompawundi ayodini zomgquba ingasetyenziswa ukulungiselela iinjongo amayeza kelp. I protein yezityalo ikhuthaza nokwenziwa, ukufunxeka calcium, phosphorus, intsimbi, kwandisa ithoni kwemithambo yegazi.
