La iseli lesilwanyana Lelinye leeyunithi ezisisiseko kwaye zibalulekile kubukho bezinto eziphilayo kwaye ngenxa yoko zinokufumaneka kwizicubu zazo. Nangona zincinci, zenziwe ngohlobo oluntsonkothileyo ekufuneka lwaziwe.
Iseli lesilwanyana kuthiwa luhlobo lwe iseli ye-eukaryoticOko kukuthi, abo banenucleus yeseli elungelelaniswe kakuhle. Ngapha koko, igutyungelwe yile nto ibizwa ngokuba yimvulophu yenyukliya kunye nezinye iindawo. Ke, sikhankanya nganye nganye, kunye neempawu zazo ezahlukeneyo.
Yintoni iseli yezilwanyana
Ngokubanzi sinako Chaza iseli yezilwanyana njengeyunithi okanye uhlobo lweseli ye-eukaryotic, Ebaluleke kakhulu kwizilwanyana okanye kwizinto ze- 'Animalia'. Olu hlobo lweeseli luya kulawula ukwenza iinkqubo ezinje ngokuvelisa amandla okanye ukusebenza kakuhle kwemetabolism. Ke ziya kufumaneka kwizicubu. Kuba iiseli ezenza imisebenzi efanayo zihlala zimanyene ukwenza oko kubizwa ngokuba zizicubu. Emva koko, izicubu ziya kulungelelaniswa ukuba zivelise amalungu kwaye ezi ziinkqubo. Iseti yeeyunithi ezisisiseko ezizezona zibaluleke kakhulu nezenza izinto eziphilayo.
Ubume kunye neendawo zeseli yezilwanyana
Kufuneka kukhankanywe ukuba iindawo eziphambili zeseli yezilwanyana zintathu eziphambili: imvulophu yeseli, i-cytoplasm kunye ne-nucleus yeseli. Nangona ngaphakathi kwezinye zezi nxalenye, sifumana organelles zeselula okanye izakhiwo ukuba nazo zifanele ukukhankanywa, ekubeni ziqhubeka ukuba iinxalenye ezibalulekileyo iseli uthe.
- La Imvulophu yeseli eyenziwe ngembumba yeseli. Nangona ikwabizwa ngokuba yincam yeplasma. Luhlobo lomaleko oluya kunciphisa iseli iphela. Ngamashiti amabini eprotein kunye neeglycolipids eziza kugcina ibhalansi ngaphakathi. Ngapha koko, umsebenzi wayo kukulawula ukungena okanye ukuphuma kwezinto ezithile.
- El icytoplasm yinxalenye yezinto eziphilayo zeseli. Oko kukuthi, ingaphakathi leseli phakathi kwenucleus kunye nenwebu. Yenziwe ngezinto kunye neekhemikhali. Amanzi, iiproteni, iicarbohydrate kunye neepid ziya kuba yile nto siyifumana kuyo.
- La mitochondria sisakhiwo esincinci esine-membrane ephindwe kabini. Umsebenzi wawo iya kuba kukuguqula izondlo zibe ngamandla, ezakubizwa ngokuba ngamafutha eselfowuni.
- El Lysosome Luhlobo lwengxowa ejongene noku kubizwa ngokuba 'kukucola kweselula'. Oko kukuthi, kweenkqubo okanye iimpendulo ezenzeka kwiseli. Zifumaneka kuzo zonke iiseli zezilwanyana kwaye zinokuhluka. Banobume obungqongqo kwaye bajikelezwe yimbumba elula.
- El Izixhobo zeGolgi inokufumaneka kwiiseli zezilwanyana kodwa nakwiiseli zezityalo. Ngumyalelo wokuhambisa iiproteni.
- El i-endoplasmic reticulum Yindibaniselwano yeembumba ezimile okweengxowa ezisicaba kwaye ziqhagamshelene. Umsebenzi wawo kukucwangcisa inwebu ngokwemisebenzi eyahlukeneyo abayenzayo. Singayifumana i-endoplasmic reticulum egudileyo okanye erhabaxa.
- El Centriole Kuyinto organelle ukuba imile cylindrical. Ziyabandakanyeka kulwahlulo lweseli, zigcina imilo efanelekileyo yeseli nganye.
- Akuthandabuzeki i-nucleus yenye yezona ndawo zibaluleke kakhulu kwiseli nganye, zombini imifuno kunye nezilwanyana. Ingqukuva kwaye ngaphakathi kuyo zombini iiMolekyuli kunye neeproteni zilungelelaniswe zangama chromosomes
- I-nucleoplasm yahlulwe kuyo yonke iseli ngenwebu ephindwe kabini apho i-nucleoplasm iya khona.
- I-Chromatin iseti yeDNA Kunye neeproteni ezifumaneka kwinxalenye yeseli kwaye zenza ufuzo lweeseli.
- Xa sithetha ngenye yeengingqi ezingundoqo, kuya kufuneka sikhankanye nucleolus. Nguye olawula umjikelo weseli, onoxanduva lokuguga.
Iindidi zeseli zezilwanyana
Kuthiwa, njengomgaqo ngokubanzi, ukuze kubekho iintlobo ezingaphezu kwe-200 zeeseli zezilwanyana. Ngaphakathi kubo, ukuhlelwa kwezona zibalulekileyo okanye ezifanelekileyo kunokwenziwa.
- Iiseli zegazi: Sidibana Iiseli ezibomvu zegazi. Ukujongana nokuphatha ioksijini kwizitho ezahlukeneyo. Kwelinye icala, kukho iiseli ezimhlophe zegazi eziza kukhusela kulo naluphi na usulelo okanye isifo.
- Iiseli zemisiphaNgaphakathi kwezihlunu siza kufumana iintlobo ezintathu ezahlukeneyo. Amathambo ancanyathiselwe ithambo kunye noncedo ekuhambeni kwayo. Kwelinye icala sinezinto ezigudileyo, ezibangela intshukumo yokungazibandakanyi kunye neentliziyo.
- Epithelial: Banoxanduva lokugubungela umphandle womzimba kunye namalungu.
- Las iiseli zemithambo-luvo banxibelelana nabanye kwaye benze inkqubo yeemvakalelo. Phakathi kwazo kukho uvakalelo, umbutho kunye neemoto.
