Yokuhlala - ukuba ubomi!

Ukuba uyakhumbula indlela biology, iseli - iyunithi noshowo kwaye zisebenza naluphi esiphilayo. Yintoni esiya kuthi, nokuba kukho loo eziphilayo nenika iseli enye kuphela. Ngenxa yoko igama - elilodwa. Kodwa umzimba kwezilwanyana kunye nabantu nje uluhlu okukhulu iiseli. Masikhumbule isakhiwo iiseli.

Zonke iseli emzimbeni wethu lingqongwe yayisoma special yokhuselo, leyo ibizwa ngokuba "ndizayo". Ngaphakathi le kernel. Kubalulekile ukuqaphela ukuba akukho zonke iiseli zomzimba ziqulathe nuclei. Ngokomzekelo, njengoko iiseli igazi lakhe ezibomvu balahlekelwa ekukhuleni kwabo. Xa iiseli izihlunu striated, phezu koko, akukho ezingundoqo mnye, kodwa eziliqela. Njengoko kukhankanyiwe ngasentla, kukho okhethekileyo cell plasma ndizayo. Owona msebenzi wayo - ngokuqinisekisa intsebenziswano kunye iiseli ezikufutshane kunye nokusingqongileyo. Ekubeni ndinobo inwebu iiseli kuzo zonke iimveliso ezingeyomfuneko pathways, kwakunye ukufumana iyimfuneko ukuze isikolo sisebenze eqhelekileyo mba, singatsho ukuba - enye yeendima ezibalulekileyo. Ukukhutshwa lwesiyobisi, phezu koko, imveliso sabo nokuba umgaqo kwe-, nokuba ngu esebenzayo yothutho iindlela ezizodwa.

Core - yenye licandelo obalulekileyo unit noshowo a esiphilayo, ebizwa ngokuba "iiseli." Le organelle encinane ungqukuva, nto leyo kudlala indima ebalulekileyo nokulawulwa kweenkqubo zeselula, kwaye kananjalo uthwele ulwazi yemfuza kuyimfuneko. Ngundoqo ngayo inwebu yayo, nto leyo efunekayo ukuze bazahlule kuyo ukusuka kukho icytoplasm.

Ukuze uqinisekise ukubaluleka ngumongo kubomi yeseli, izazinzulu ziye baqhube imifuniselo eziliqela. umongo yabo sikuko into yokuba xa amoebae usebenzisa inaliti esikhethekileyo isuswe isiqalo. Kwiintsuku ezimbalwa emva amoeba nokuqhathwa wafa. Hayi, yena akazange ayeke ukuba adle, kodwa wahlala phantse kuzo zonke iinkqubo. Kakade ke, siya kucinga ukuba amoeba kufa ngenxa kuqhutywa "umsebenzi", kodwa amava, apho olungundoqo singesuki kuphindwa, kodwa nje ezinambuzelayo oko kwabonisa ukuba amoeba ngenxa kuphazamiseka akafi.

organelle Okulandelayo, ngaphandle ongayi kuba akukho iseli - kuba mitochondria. It ingqongwe inwebu kabini. Eyona umsebenzi lo sostavlyayushey naziphi na iiseli - imveliso ATP zizithuthi electron kunye neenkqubo phosphorylation oxidative. Nangona isibakala sokuba mitochondria babe DNA zabo, iiprotheni zayo beminwe ngokuba yi-DNA, ophuma kukho icytoplasm. Ngenxa yokuba amandla kubalulekile ebomini nokusebenza eyiyo zonke iiseli, ukubaluleka kwale organelle iba kakhulu kubalulekile ukuba isakhiwo efana esiseleni. Isakhiwo ngasinye mitochondria ngokulinganayo kwaye akukho umahluko. Kukho imifinya ezimbini, eyokuqala apho zangaphezulu kwaye isebenza ukwahlula mitochondria ukusuka kukho icytoplasm. Okwesibini - embilwini, yangaphandle wahlukana kwisithuba intermembrane of mitochondria kwaye ikhusela imixholo ukuba zingene ezivela ngaphandle.

Ngamnye organelles iseli kubaluleke ngokukodwa, ngoko ke kunzima kakhulu ukuchonga ngokungeyomfuneko kuyimfuneko. Yokuhlala - ukuba ubomi!
