Diatoms

Ulwandle namanzi okuphuza, kanye inhlabathi ezimanzi sikhule diatoms. Brown lezi zitshalo ukunikeza ophuzi onsundu photosynthesis zombala. I engavamile kulezi ulwelwe ukuthi amaseli wabo bavikelekile ngaphandle igobolondo kanzima - frustuloy (igobolondo). Izitshalo kukhule kokubili ngamunye futhi amakoloni. Zidla izinto ikakhulukazi eziphilayo imvelo.

Diatoms akheke esiyingqayizivele. La mangqamuzana aqukethe enezinto ezimbili (epiteki futhi hypotheca). udonga Frustuly ifakwe ikhule ezimbotsheni okuyothi ngalo exchange of izinto nge imvelo. Ezinye izitshalo abe ukuvulwa slot emise eduze Igobolondo liyakwazi usebenzisa isikhwehlela ukuhambisa kanye substrate.

Breed ulwelwe, njengazo zonke izinto eziphilayo, division. Ukuthola ingxenye igobolondo umzali, inkampani ephethwe iseli kuqala ukukhula ngenkuthalo. Nokho, frustula ubudala ithumba izinjongo zabo entsha. Kusukela eziqinile ulwelwesi amaseli cishe akanamandla ukukhula okwalandela ulwelwe enqubeni yokuzalana zincipha kubonakale. Nokho, ngenxa auxospore ekwakhekeni, okuqukethwe plant cells uyakwazi ukuphuma igobolondo bese uqale division entsha. Ngesikhathi esifanayo esizukulwaneni esisha of diatoms kuyoba kakhulu kunangendlela kulowo odlule.

Lesitshalo ulwelwe:

• Melozira. Lolu hlobo uhlala amanzi anosawoti bese ngamanzi agobhozayo. Anamandla ihlinzekwa ngokusebenzisa inqubo ye-photosynthesis. Lezi diatoms ngokuyinhloko esetshenziselwa begazi ukuhlaziywa amanzi, sokunquma degree ukungcoliswa kwesigubhu.
• Gomfonema. Izitshalo kwalesi silwane sikhule emanzini ahlanzekile. Bona babiza ulwelwe noma ezinye izinto ezihlukahlukene ezitholakala ezansi futhi ukwakha amakoloni zabo. Lolu hlobo linesizotha kuya izimo lokushisa. Ukuze molluscs, lezi ulwelwe kukhona kunomsoco impahla eyigugu.
• Plevrosigma. Lezi zitshalo ezitholakala emanzini brackish zasolwandle lapho ngukudla izinhlanzi ezincane.
• Sinedra. Diatoms kuleli qembu izitshalo owumphumela. Zakha amakoloni efana isimo sabo izinyanda fan. Njengengxenye 'ngenkosi' yayo zikhetha ulwelwe oluhlaza noma plankton. ukukhahlamezeka kwendawo Sinedry - emfuleni kancane ugeleza emi amanzi. Lolu hlobo asifanele izinhlanzi umsoco.
• Navicula. Lezi ulwelwe zingatholakala kuyo yonke indawo. Babonakala phansi ezinodaka angenasawoti, emadwaleni ezimanzi nomhlabathi.
• Pinnulyariya. Diatoms yalolu hlobo zitholakala ezindaweni ezinodaka emadanyini Amasimu erayisi. Ngenxa ukumelana layo eliphezulu okushisa bahlala cishe kuzo zonke izingxenye emhlabeni. Leaf simila amaseli kuyagcinwa odakeni kahle. Ngenxa yalesi sici imiphakathi pinnulyarii babe ukusebenza eliphezulu.

Seaweed kelp sikhule eliseMpumalanga Ekude futhi ugu wezilwandle enyakatho. Ubude yabo kungaba kusuka 2 kuya ku-6 metres, ububanzi - 35 cm. isitshalo ekhetha ezindaweni ezinamadwala ukuze baphile. Kuye ngokuthi izimo sezulu zasolwandle bempilo ephakathi kuka 2 no-4.

Okusakazwa kelp ezinhlamvu zazo akhiwa besilisa prothallia zesifazane. Bakha gametes (germ cells). Ngemva kweqanda we esibelethweni evela abasha sporonosyaschaya kelp.

Kelp is kabanzi kwezokwelapha, ukupheka kanye izimonyo.

Thallus kelp bathathwa ukudla. Izitshalo etholwe salads omkhulu, amasobho, breads kanye amaswidi. Ngo Cosmetology esetshenziswa amafutha kanye ulwelwe ezikhishwe. Ukuba khona organic iodine compounds kungenziwa esetshenziselwa ukwenza umuthi kelp. I amaprotheni isitshalo ikhuthaza nokwenziwa, ukumuncwa kwe-calcium, phosphorus, okusansimbi, kwandisa ithoni imithambo yegazi.
