Ihlabathi elimangalisayo: ekhusela iseli sihlahla ngaphandle?

Kweli nqaku uza kufunda ukuba ikhusela iseli sihlahla ngaphandle. kwaye nathi siza kuqwalasela isakhiwo jikelele weseli zezityalo, sandise lawo zakho. Ngoko ke, yintoni ikhusela iseli sihlahla ngaphandle? 3 iklasi yemfundo jikelele kufuneka uqiniseke ukuba bakucacisele abantwana bakho.

Lo mba ubaluleke kakhulu, sele abantwana besikolo samabanga kufuneka siqonde ukuba yonke into kweli hlabathi wethu kwenziwe ngeeseli ezahlukeneyo. Baye izakhiwo ezahlukeneyo kunye nemisebenzi. Cage ingabonwa kuphela ngemicroscope, ngoko yayimfutshane ngesithomo. Kodwa kukho amacandelo ezincinane ekuthiwa organelles. Siqala ibali lethu ulwazi.

Iseli plant: isakhiwo

Ngoko ke, siye safumanisa ukuba iseli - ukuba yinxalenye Umenzi zonke izinto eziphilayo emhlabeni. Asazi nje ziwe ezulwini, yaye kangangexesha elide baye bavela izidalwa olunye-elilodwa. Ngoko ke iseli kusisiphumo nasekusungulweni ephilayo. Umzimba elakhiwa inani eyahlukileyo yabo - 1 ukuya billion eziliqela. Ngoko ke kucacile ukuba khona iseli njengequmrhu eyahlukileyo, kwaye enze yonke imisebenzi eyimfuneko.

Okokuqala, ekhusela iseli sihlahla ngaphandle. Iseli nganye wambu uhlobo eludongeni, ebizwa iseli ndizayo. Asinto yonke indawo ubukhulu efanayo, kwezinye iindawo, iye pores apho iba utshintshiselwano kwezinto phakathi iiseli kunokwenzeka. Ngoko ke, yintoni ikhusela iseli sihlahla ngaphandle, siye safumanisa.

Abangaphakathi:

• protoplast;
• Yezabelo.

Umahluko omkhulu kwezi zinto kukuba protoplast - into ephilayo kunye nezakhi zayo - akukho. Protoplast, nto, nto ndiyibhalayo ziqendwana zilandelayo:

• kukho icytoplasm;
• core.

Ngomhla umbuzo wokuba yintoni ukukhusela iseli zezityalo ezivela ngaphandle, impendulo sifumene, ngoku kubalulekile ukuqwalasela ubume kunye iseli nodonga umsebenzi.

cell udonga

Xa kuthelekiswa iiseli izityalo kunye nezilwanyana qaphela ukuba iindonga esicacisa iseli kunokuba kuphela kwizityalo. Yena uye isakhiwo kunokuba okuqinileyo, njengoko wenza imisebenzi ethile ebaluleke kakhulu, nto leyo esiza kuxubusha ngalo kwicandelo elilandelayo. Omnye wemisebenzi esele zikhankanywe apha etafileni yemixholo eli nqaku: Ukhusela iseli sihlahla ngaphandle. Ngokusisiseko, le nto ndiyibhalayo kwincindi. Kwakhona, kukho iiseli azinayo le nto inwebu, njengoko zazibizwa - protoplast.

Yiyiphi enye into ebalulekileyo kukuba ukuqaqambisa ulwakhiwo iindonga? Kakade ke, ubukho pores. Pores zenza ezingontsingontsini ukuzamazamana kunye yokucolwa phakathi iiseli ezikufutshane.

imisebenzi

Umba yokugqibela umsebenzi wethu kukhethwe yonke imisebenzi eyenziwa yi udonga olukhuselayo plant cells. Sinikezela ukudwelisa nabo kuluhlu:

• amandla mechanical;
• Ukunikela;
• uqine nokwandiswa;
• ulawulo ukukhula;
• ulawulo imilo;
• amanzi umqhubi nezithako;
• Uthintelo ukulahleka Water;
• ukunciphisa iseli ukungena amagciwane ezimbi;
• agents izithuthi;
• isiHindi stock;
• kubeke stock.

Njengoko ubona, inxalenye iindonga mkhulu kakhulu.
