Cell bango aiki: support, kai, aminci

A surface naúrar ne wani ɓangare na kowane cell, kuma da yawa na da aka gyara. Shi aikin da harshen damo. Ta yaya jikin tantanin sifa da aiki na tsarin - duk za a tattauna a cikin labarin.

jikin tantanin tsarin

Kowa ya san cewa tantanin halitta shine mafi karami tsarin da kuma aikin naúrar na jiki, kuma ta main sassa ne surface naúrar, da cytoplasm da wasu gabbansa. Duk da haka, da tsarin za a iya bincika a wani daban-daban hanya. Duk wani cell ne a tsarin da nazarin halittu membranes. Fassara daga Latin, da kalmar na nufin "film" ko "bawo". Saboda haka, a kan saman Kwayoyin an rufe tare da jini membrane. Amma da ciki yanayi na cell ne zuwa kashi segments ta hanyar wadannan ciki Tsarin. Wannan tsarin samar da sarari rarraba daban-daban abubuwa da kuma sunadarai matakai.

Tsari da kuma aiki na cell membranes

A halin yanzu model na tsarin nazarin halittu membranes ake kira ruwa-mosaic. A da ginshikin ne biyu Layer na lipids, hydrophilic rabo daga abin da fuskantar zahiri. Wannan phosphate kungiyoyin wadannan abubuwa. Amma da hydrophobic bangare na lipids, waxanda suke da m acid fili baƙin bilayer. A gaba bangaren cell membranes ne sunadaran. Wasu daga cikin su suna located a kan waje surface da kuma sauran sia bilayer shiga zuwa daban-daban zurfin. Wannan tsarin damar da cell a gudanar da hadadden tsarin da kariya, yadawa, phage da pinocytosis.

A cikin jini membrane na hadaddun aka located, yin ƙarin ayyuka. A shuka Kwayoyin, fungi da kwayoyin cuta, suna gabatar da cell bango. Amma a cikin dabbobi irin wannan tsarin ne glycocalyx. Yana bayar da wani kai tsaye mahada tare da cell yanayi da daidaitawa da zabe ci daga abubuwa. The ayyuka na cell bango tsarin saboda da siffofin waxanda suke da ɗan daban-daban daga cikin tsarin irin dabba Kwayoyin.

Abun da ke ciki na cell bango

A sunadarai tsarin da cell bango a daban-daban kungiyoyin na dama daban-daban kwayoyin. A shuke-shuke, shi ne mafi m. Wannan dukiyar da aka bayar da gaban da aka tattara a cikin daure insoluble cellulose zaruruwa. Yana da wannan hadaddun carbohydrate a haɗe zuwa cell ganuwar da tsire-tsire rigidity da kuma ƙarfi. Za mu iya cewa shi Forms wani irin firam. A abun da ke ciki na cell bango da ayyuka a daban-daban nama daban na iya bambanta ƙwarai. Alal misali, a kan lokaci da Kwayoyin kasance daya daga cikin iri na masana'anta murfin, da ake kira tube, impregnated da kitsen-dauke da suberin. A sakamakon haka ne da mutuwa na ciki abun ciki da kuma bada goyan baya da ayyuka. A irin wannan tsari ne ya lura a cikin sel na jijiyoyin bugun gini nama na shuke-shuke, wato a cikin tasoshin. Su ne m Tsarin, game da shi, sa shi yiwuwa a gudanar da abubuwa. odrevesneveniya tsari ne saboda gaskiyar cewa gibba tsakanin ɓangaren litattafan almara zaruruwa cika wani hadadden carbohydrate - lignin. Yana muhimmanci ƙara ƙarfi daga cikin surface na'ura.

A fungi cell bango polysaccharides dokoki da akai ma. Duk da haka, ba m cellulose, kuma chitin da glycogen. Yana da wani fasalin na tsarin, abin da ya sa su dabbobi. Amma da aiki na kwayan cell bango samar da wani hadadden mix na carbohydrates da kuma sunadarai. Shi ne ake kira peptidoglycan ko murein. Wannan abu ne kawai halayyar prokaryotic kwayoyin da kuma yin inji ayyuka.

The ayyuka na cell bango

Duk da gagarumin bambance-bambance a cikin sinadaran abun da ke ciki na cell ganuwar daban-daban kungiyoyin na kwayoyin da irin wannan specialization. Su main aiki ne don samar da goyon baya, da kuma kariya metabolism. Cell bango kula akai siffar. Wannan zai kare duk ciki abinda ke ciki na inji effects na muhalli. cell bango ayyuka ne ma a cikin aiwatar da a ci gaba da aiwatar da ruwa shigar da cell da sinadarin gina jiki abubuwa narkar da a cikinta a cikin Reverse shugabanci.

A permeability na cell bango

Rayuwa tsari wanda cell bango, mai yiwuwa ne saboda ta permeability. Wannan dukiyar aka bayyana a cikin aiwatar da biyu kishiya tafiyar matakai. A farko an kira plasmolysis. Ya kunshi a cikin cytoplasm delamination Layer located nan da nan m cell bango. Wannan na bukatar wani yanayi. Plasmolysis faruwa, misali ta hanyar ajiye keji da wata babbar taro na gishiri fiye da a da kansa cytoplasm. A baya tsari shine ake kira deplazmolizom.

Ta hanyar pores da suke a cikin cell ganuwar, kuma metabolism ya auku a tsakanin sel. Nan da nan wannan ne yake aikata ta hanyar plasmodesmata. Wadannan tsarin ne da shari abubuwa. Sun wuce ta cikin jini membrane kuma suna m shambura a haɗa EPS makwabtaka Kwayoyin. Yana da yake a wadannan gabbai, da kira da kuma jari na cikin abubuwa wajibi ne ga ci gaban da kwayoyin.

Saboda haka, jikin tantanin sifa da aiki da abin da muka gani a cikin labarin, shi ne kowa da kowa kwayoyin. Mun shuka da kuma kwayan kwayoyin, da kuma fungi a kan shi ne cell bango. An kafa ta polysaccharides cewa ba shi ƙarfi. Babban aiki na cell bango - ne kariya, goyon baya da kuma sufuri na abubuwa.
