Vacuole ndi ... Ntchito za cell vacuole

Lero tidzakambirana za zomwe zapanda. Ili ndilo gawo lina la selo, ndiko kuti, organoid. The organoid, kapena organelle, ndiyo magulu omwe maselo amapangidwa, ndikumapeto kwake, ndizo maziko a chirichonse chomwe chikutizungulira.

Ndipotu, dziko silili momwe likuwonekera poyamba. Ndikoyenera kutenga microscope, ndipo maganizo athu amatha kusintha kwambiri. Chidziwitso choyamba ndi chipangizo ichi chiri pasukulu ya kusekondale. Aphunzitsi ayenera kupereka chidziwitso pa malamulo ogwiritsira ntchito microscope popewa zochitika zosasangalatsa mu phunziro losangalatsa. Pambuyo pang'onopang'ono, tiyeni tikuuzeni za chomwe chitsimikizireni. Ili ndi funso lathu lalikulu.

Vacuole

Tiyeni tiyambe ndi tanthauzo. Vacuole ndi organoid (memphane imodzi). Amapezeka m'maselo a eukaryotic. Yambitsani mwatsatanetsatane zazing'ono: ma eukaryotes ndi maselo omwe ali ndi pathupi. Chotsitsacho chimasiyanitsidwa ndi cytoplasm ndi membrane iwiri. Mtengo wa pathupi ndi waukulu, uli ndi DNA ya molekyulu.

Choncho, vacuole ndi organoid yomwe ikhoza kugwira ntchito zosiyanasiyana (tidzakambirana za iwo mtsogolo). Kodi ma organelleswa amapanga bwanji? Iwo amachokera ku provakuols, ndipo amawonekera pamaso pathu ngati mawonekedwe a membrane vesicles.

Ndikofunika kudziwa kuti mavitamini onse angathe kugawa m'magulu awiri:

• Kudula;
• Kuphulika.

Nthawi zina kupuma kumatchedwa contractile. Amathandizira kupeza zowonongeka. Ndi zina zotani zomwe sizikuyenda bwino, tidzakambirana pang'ono.

M'maselo obzala, zotupa zimatenga pafupifupi theka la voliyumu, nthawizina zimagwirizanitsa mu organoid imodzi yaikulu, yomwe imaposa kwambiri kukula kwake.

Zonsezi zimaperewera ndi nembanemba, imatchedwa tonoplast. M'kati, tikhoza kuzindikira kuchepa kwa selo. Zomalizazi zili ndi zigawo zotsatirazi:

• Madzi;
• Monosaccharides;
• Ma disaccharides;
• Matauni;
• Zakudya Zam'madzi;
• Nitrates;
• Phosphates;
• Chlorides;
• Mavitamini a thupi ndi zinthu zina.

Ntchito

Tsopano ife tikukonzekera kuti tiwonetsere ntchito zazikulu za organelles zomwe zikuganiziridwa. Vacuole, omwe ntchito zathu zomwe talemba, angathe kutenga gawo la selo kuyambira 5 mpaka 90 peresenti. Cholinga chake chimadalira kumene organello ili.

Ponena za mitundu ya maselo, pali zambiri mu maselo a zomera, ndipo zinyama zimakhala ndi ziwalo zazing'ono. Ife tanena kale kuti, malingana ndi malo, opuole akhoza kuchita ntchito zosiyanasiyana. Koma tidzasiyanitsa zazikulu ziwiri:

• Kusiyana kwa organelles;
• Ntchito yamtundu.

Chomera chomera

Tsopano timaphunzira zambiri za organelles mu selo la zomera. Selo limatuluka ndilo chigawo chake chachikulu. Tiyeni tilembe chifukwa chake:

• Vacuole amamwa madzi;
• Chotsani zinthu zovulaza;
• Nthawi zina, zimbudzi zimatulutsa madzi amadzi;
• Kuthandizira pakugawaniza organelles wakale;
• Sungani zakudya.

Monga momwe mukuonera, udindo wa organoids ndi wabwino kwambiri. Tinatchula kuti amatha kupatulira organoids akale, ndiko kuti, amachititsa ntchito ya lysosomes. Motero, vacuoles akhoza kukhala ndi michere yofunikira kuti hydrolysis ya zinthu zotsatirazi:

• Mapuloteni;
• Mafuta;
• Zakudya Zam'madzi;
• Nucleic acids;
• Mafano;
• Phytoncides ndi zina zotero.

Amagwiranso nawo ntchito yopanga photosynthesis, yomwe ili yofunikira kwambiri osati kwa zomera zokha, komanso kwa zamoyo zina.

Cell Cell

Zopupa zitha kupezeka:

• Madzi a m'nyanja ;
• Multicellular invertebrates.

Pachiyambi choyamba, timakumana ndi vacuoles a contractile, omwe amagwira ntchito monga olamulira. Izi zikutanthauza kuti amatha kutulutsa kapena kutulutsa madzi owonjezera. Kwa gulu lachiwiri tingathe kuphatikizapo zamoyo zambiri, zomwe:

• Sponges;
• Coelenterates;
• Nyongolotsi zolimbidwa;
• Mabokosi.

Zamoyo zimenezi zimapanga kupuma kwapang'onopang'ono, komwe kumatha kupangidwanso. Zomalizazi zimatha kukhazikitsanso nyama zakutchire, koma m'maselo ena (phagocytes).
