Biology: Ilaphu - iqela leeseli ezifanayo kubume kunye nokusebenza

Ngokutsho biology, izicwili - isakhiwo eyodwa eqinisekisa ukusebenza kwawo nawuphi na ephilayo xa iyonke. Ziziphi iimpawu zezakhiwo kufuneka ilifa ukuze wenze lo msebenzi ubalulekileyo?

Yintoni eli laphu eziphilayo uya kuphendula

Ngokutsho inkcazelo, eli laphu liqela leeseli, efanayo isakhiwo umsebenzi. Ayizizo zonke izinto eziphilayo akhiwa nezakhiwo ezikwanjalo. Ngenxa yoko, iintsholongwane iindlela ezingezo-cellular ebomini, yaye zonke iintsholongwane - single-elilodwa.

amaqela ezizodwa weeseli kuvumela zonke nokomzimba ngokuyimpumelelo. Ngoko ke ehlelekile izinto eziphilayo zenziwe ngamalungu. Oku kubonisa biology. Ilaphu - it nje isakhiwo eyakhiwa zeeseli amalungu ngokwakha.

plant lolwabo

Yintoni na le laphu? Plant eziphilayo lubonise ukuba kuphela kwiiseli. Phakathi kwazo kukho kwento intercellular, owenza umsebenzi kwebhulorho. Plant inyama ngayo phantse kude.

Bona zimelwe ezi ndidi zilandelayo:

1. I-inshorensi:

- amaxolo - a tissue eliphilayo isakhiwo ezikhethekileyo - yokondliwa ukukhonza utshintsho gas;

- ityhubhu - nyama apho ukutya abathwele lenticels.

2. Summary - Iivenkile izondlo, uwugcinayo inkqubo yefotosinthesis, nto yakha isiseko unyanzeliso.

3. Mechanical - ezisebenza umsebenzi exhasayo.

4. Conductive - kunika phezulu (amanzi avela ingcambu) kunye downlink (organic zingangeni amagqabi) izinto yangoku.

5. Imfundo - ngokuthi iiseli ngokwahlula ibuyisela nayiphi izihlunu ababesifa, ekuqhubeni ngokutsha.

ijwabu zezilwanyana

A phawu yale iqela leeseli kuba phambi oluninzi matrix extracellular.

Izilwanyana zihlelwa alandelayo emzimbeni:

1. Epithelial - la engenamsebenzi olukhuselayo. Kwakhona sakha indlala kwaye uthwala ukutya. I lolwabo kwakhiwa epithelial? Biology kulula: i, iiseli ezincinane tight-gingci ezahlukeneyo ezimise.

2. Coupling - iqulathe iiseli ezinkulu kwaye inani elikhulu kweziyobisi intercellular. Yeyona sisiseko yonke eziphilayo. iintlobo zayo igazi, ithambo, intlala, okanye izityalo adipose.

3. Muscle - bafanekiselwa imicu ngamnye, ekwaziyo lokunciphisa - myofibrils. Banakho ukunika umzimba ihamba emajukujukwini kunye nentshukumo amalungu ngamnye.

4. uvalo - inxibelelanisa umzimba kunye nokusingqongileyo, iziphumo phambi ikhaliphe moya, kwaye isegazini. Le nto ndiyibhalayo iiseli ekuthiwa luvo kunye neenkqubo zabo - axons kunye luvo. Kungenxa kuye ulwazi usasazwa ugqithiselwa ukusuka kwinkqubo womenzi woluvo kule zemizwa ingqondo, yaye ukusuka apho - izidumbu zokusebenza.

Ukuzalana isakhiwo kunye nemisebenzi

Kodwa okona kubaluleke kakhulu, njengoko inzululwazi eziphilayo, izicwili - iqela leeseli, leyo ukusebenza ngenxa yokuba ubume babo.

Umzekelo, encinane, ngokusondeleyo bebekwe iiseli epithelial, phantse akanayo ubuncwane intercellular, njengekhaka. Eneempawu ezinjalo kwezakhiwo phawu ezicacileyo - ukukhuselwa. Ngendlela eyahlukileyo amalungiselelo kwizicwili. Kuba sisiseko onke amalungu, kufuneka ibe nenala. Oku kuchaza ubukho iiseli ezinkulu kwaye inani elikhulu kweziyobisi intercellular. Ingakumbi kakhulu kulo egazini. Le into kuye kwafika kubo bonke, ekuthiwa plasma. Ine corpuscles. Iiseli ezibomvu egazini - iiseli ezibomvu zegazi - oksijini zothutho ukusuka nemiphunga amalungu kunye carbon dioxide kwicala umva. Zegazi - zegazi ukukhuthaza ekunqandeni ukopha. Iiseli zegazi ezimhlophe - iiseli enemibala. Bakha amajoni omzimba, ukunceda umzimba ukuxhathisa izifo ezosulelayo.

Amalaphu kwemvelo

Yintoni ijwabu ibhayoloji ingqalelo ngoko nangoko. Oku kuphela kokusungulwa microscope ukukhanya kutyhilwa an amazing umntu umfanekiso obungabonakaliyo esiseleni, kwaye nalo emzimbeni.

izityalo Lower, eziquka ulele, tissue musa ukuba. Kwaye abameli babo multicellular bezibandakanya iiseli ezizodwa non-ngamnye zingasebenzi ezingazalaniyo. Ngokubhekele phaya, kunye ukutshintsha iimeko zemozulu on Earth baba emifuno yokuqala ukuza elunxwemeni. Ngokutsho biology, izicwili - imeko ayimfuneko ukuphila kwabo kwindawo entsha. In moss and moss baba kuqala izihlunu ngomatshini, kuyimfuneko ukuba amalungiselelo wabo lomhlaba. Kwaye ngoko - kunye nenkcitho. Olu phuhliso yakhokelela ekwakhiweni kwezi amalungu: iingcambu namasebe.

Izilwanyana ezininzi abangekaphuhli multicellular kwaye akukho kwizihlunu lokwenene. Sithetha ummeli uhlobo Coelenterates amanzi hydra. Umzimba wakhe ukhandwa iiseli ezikhethekileyo :. Epithelial, izihlunu, ngokwesondo, isikhumba-eqatha, glandular, njl Kodwa ezizo amaqela, kwaye saa kuwo wonke umzimba.

Ngenxa yoko, imbonakalo amalaphu yaba sisiqalo ukuntsonkotha ubume eziphilayo, nto leyo evumela silungelelanise ngcono kuyo nayiphi na imiqathango.
