Yintoni iqela leeseli ekuthiwa iithishu? Indlela esakhiwe ngayo iiseli zomzimba

Yintoni iqela leeseli ekuthiwa iithishu? Ukuze uqonde lo mbuzo, kubalulekile ukukhumbula iimpawu yesakhiwo umsebenzi. Nalo siya kuzama ukumelana kwinqaku lethu.

Yintoni iqela leseli ebizwa emzimbeni

Tissue ithathwa iqela leseli. Kodwa asingabo bonke bephela ziyakwazi ukwakha izakhiwo ezinjalo. Ukuze uqonde ukuba yintoni iqela leeseli ekuthiwa zomzimba, kuyimfuneko ukuba bafunde imeko engundoqo. Ihlala yokuba zonke iiseli kufuneka iimpawu ezifanayo lwezakhiwo, ngoko ke lenze umsebenzi ofanayo. Kuphela xa onjalo ukwakheka zizakujongwa njengo ngeqhiya. Ngaphezu koko, kuhlanganiselo abaninzi babo hi mpimo ezahlukeneyo ziquka into intercellular, edibanisa onke amacandelo zibe iyunithi enye.

Indlela esakhiwe ngayo iiseli zomzimba

Zonke iiseli zomzimba kufuneka isicwangciso eqhelekileyo yesakhiwo. Ziqulethe uluhlu izixhobo kumphezulu, kukho icytoplasm, organelles kunye inclusions. Kodwa ngokuxhomekeke kuhlobo iiseli zeethishu babe neempawu zabo. Ngokomzekelo, iiseli zemithambo-luvo kuba umzimba waso. Esi sakhiwo sinika enye, umzimba uphela nolwalamano yayo kunye nokusingqongileyo. spikes Ngu-lwazi kwi khowudi njenge mnqweno luvo usasazwa ugqithiselwa phezu iiseli zomzimba.

Ngokungafaniyo eziphilayo multicellular kunye yamakoloniyali

Ayizizo zonke izinto iqanjwa inani elikhulu iiseli abe kwithishyu. Umzekelo iphawulekayo yale ke lisiza. Eneneni, umzimba kwabo ezenziwa ezininzi iiseli, kodwa elowo kubo alisebenzi lodwa, njengoko inkqubo ehlukeneyo. ukuba Bakha anatomically kuphela, kuba Amaqokobhe zabo ezikufutshane enye kwenye. emzimbeni ulwelwe ebizwa thallus okanye thallus. Kwaye apha eyayilithânga Volvox. Kwakhona bakha inani elikhulu leseli ezahlukeneyo. Kodwa akukho kufutshane omnye komnye yaye singqongwe imvulophu eqhelekileyo. Yena ifaka kuzo zibe eyodwa. Xa eziphilayo multicellular, iiseli zomzimba ziyakhukuliseka zidityaniswe zibe ngamaqela iimpawu zolwakhiwo ukuba akwazi ukwenza ngokudibeneyo imisebenzi ethile.

plant lolwabo

Iqela ngalinye eziphilayo na iimpawu ngesakhiwo. Iiseli, ancedisana amalungu zezityalo, umzekelo, bayakwazi yinkqubo entsonkothileyo amandla - zefotosinthesisi. Oku kungenxa yobukho organelles ezizodwa ebizwa chloroplasts. Kodwa oku uphawu kuphela ezi eziphilayo.

izixwexwe Plant zimelwe iintlobo ezintlanu. Le osithelisayo, esisiseko, mechanical, conductive kunye nemfundo. Eyokuqala kwezi ikhusela imixholo yangaphakathi kwiimpembelelo eziyingozi yokusingqongileyo kwaye uphumeza ukutya. Ngoko ke, ilungu elo laphu nesigubungelo iiseli ezincinane ukuze kuthinteleke ukubola okudalwa ukuba babe pores. Kusenokuba ibe live - Chuba kunye odrevesnevevshey nabafileyo - isivalo. Eli laphu oluphambili ufaneleke igama layo, njengokuba eneneni phantse umzimba wonke. zaso zinkulu, evakalala. Bona ziqulathe ngokuba yiklorofili.

inyama Mechanical kuvumela amalungu isityalo ukuba babe ngabantu abakwizihlalo article emajukujukwini. Ngelo xesha lithile omnye wemiqathango zezityalo imveliso yomhlaba. Elements amalaphu conductive zitya kunye neetyhubhu yokugalela. Ezi seli ezibuhlazarha evuthelweyo zinika zinyuka zisihla current kwezinto kwisityalo. Iiseli zomzimba zemfundo ephila ngamaxesha yahlula, ukwakha izinto zonke ezinye iintlobo izicwili.

ijwabu zezilwanyana

Eziphilayo isilwanyana nezinye iindidi iiseli. Amalaphu ezi zinto ziphilayo zinikwa epithelial, nokuqina, izihlunu kunye luvo. Isakhiwo ngamnye kubo kukho unxulumano phakathi isakhiwo kunye nemisebenzi. Iiseli zobuchopho epithelial zincinane, esinzulu ezikufutshane, iphaneli efanayo. Ngoko ke, zinika ukhuselo oluthembekileyo. Imizekelo uxhulumaniso ke igazi, namanqatha, ithambo kunye intlala. Ngenxa yokuba kuba sisiseko sophuhliso lomzimba, imikhulu nezinto ngesixa esikhulu kweziyobisi intercellular. Muscle movement umzimba ubonelela esithubeni. zaso zibizwa ngokuba myofibrils. Ngamnye kubo uyakwazi ukwehlisa. inyama luvo inxibelelane kunye nokusingqongileyo, ekubeni iiseli iqinile zokutyhomfa, ezenza uthungelwano ashinyeneyo.

Ke apho iqela iiseli ekuthiwa iithishu? Impendulo ilula: kuphela ezo ezifanayo kwaye kubume kunye nomsebenzi. Ngenxa mnoogobraziyu yayo, iiseli zonke izinto ekwaziyo zokubumba iintlobo ezininzi kwithishyu, nganye kubalulekile ukuba lo msebenzi.
