Vacuole - sena ... mosebetsi wa vacuoles seleng ea

Kajeno re tla bua ka seo ke vacuole. Sena ke e mong karolo ea sele, ke hore, organelles. Organelles kapa organelle - e likaroloana tse etsang lisele, ea bobeli, le eena, ke motheo oa lintho tsohle tse pota-potileng le rona.

Ha e le hantle, lefatše ha se ho bonahala ka chebo ea mahlo. E lokela ho nka ka ya microscope, 'me lefatše la rōna le tla fetoha haholo. The tloaetseng pele ka seletsa sena se etsahala ntse a le sekolong se phahameng. Mesuoe eo e lokela ho ba bonnete ba hore ho fana ka puo ea ka melao ea tshebediso ya ya microscope ho e le ho qoba liketsahalo e sa thabiseng ho jwalo mosebetsi hlollang. Ka mor'a tswe tseleng e khutšoanyane ho u bolella hore ke vacuole. Sena ke tokollong ea rōna e khōlō.

vacuole

A re ke re qala ka karolo ya tlhaloso. Vacuole - sena organelle (odnomembranny). E ka fumanoa ka lisele tse eukaryotic. Hang-hang tsebisa ka tlhaloso hakaalo: e eukaryotes - seleng e nang le liboto. qetellang e aroloa ho cytoplasm ka le lera habeli. Boleng ba khenele ke kgolo, e le hore e na le DNA molek'hule.

Kahoo vacuole - sena organelle khona ho phetha mesebetsi e mengata e fapaneng (tsa eo re se buang e nyenyane hamorao). Jwang organelles tsena di thehoa? Li simoloha ho tloha provakuoley, ha ba ntse ba hlaha ho re ka mokgwa wa vesicles lera.

Ho bohlokoa ho tseba le seo u ka se vacuoles tsohle arotsoe ka lihlopha tse peli:

• tshilong ya dijo;
• pulsating.

Ka linako tse ling pulsating vacuoles bitsoa contractile. Ba thusa ho tlosa lihlahisoa ho bola. Eng hape a etsang sena ka mesebetsi vacuole, re tla tšohla hamorao.

Ka lisele tse dimela, vacuoles lula fetang halofo molumo, ka linako tse ling ba kopane ka organelle 'ngoe e khōlō, e leng hole feta litekanyo tsa ba tloaelehileng.

Tsohle vacuole lera e feela, e bitsoa - tonoplast. Ka hare re ka fumana ka seleng la qeta. Ea bobeli e na le metsoako e latelang:

• metsi;
• monosaccharides;
• disaccharides;
• tannins;
• lik'habohaedreite;
• nitrates;
• phosphates;
• chloride;
• acid manyolo le lintho tse ling.

mesebetsi

Hona joale re fana ka ho abelwang karolo ya mesebetsi mantlha nkoa ke re organelles. Vacuole, eo hona joale re thathamisa mesebetsi ea ka e nkang e le sebaka seleng ea ho tloha 5 ho ea ho karolo ea 90 lekholong. Abela e itšetlehile ka moo organelle ena ke.

Mabapi le mefuta e ea lisele ka semela na le ba bangata ho feta, 'me liphoofolo li ba le organelles nako. Re se re boletse hore, ho itšetlehile ka lefelo la vacuole le ka phetha mesebetsi e sa tšoaneng. Empa re Single tsoa ba tse peli tse khōlō:

• kamano ea organelles;
• ho tsamaisa mosebetsi.

seleng ea dimela

Hona joale re tsoele pele ho ithuta boitsebiso bo eketsehileng ka organelles liseleng semela. Cell vacuole - ena ke karolo ea eona e khōlō. A re ke re thathamisa hobaneng:

• vacuole monyang metsi;
• Ho tlosa lintho tse kotsi;
• maemong a mang vacuoles hlahisa amohang Milky;
• amehang mosebetsing oa ho ea petsoha ea organelles khale;
• ipolokele limatlafatsi.

Joalokaha u ka bona, organelles tsena phetha karolo e khōlō hlile. A na re bolele hore ba ba khona ho heletsa le organelles khale, ke hore, ho phetha ho sebetsa ha lysosomes. Kahoo, vacuole ka ba le potlakisang tsebetso ea lik'hemik'hale tse hlokahalang bakeng sa hydrolysis ya dintho tse latelang:

• liprotheine;
• mafura;
• lik'habohaedreite;
• acid nucleic;
• phytohormones;
• tlhahiso ea ho hloka botsitso, 'me joalo-joalo.

Ba ile ba boela ba amehang mosebetsing oa ho ba tala, eo ke ntho ea bohlokoa, e seng feela ho dimela empa le bakeng sa lintho tse ling.

zooblast

Vacuoles ka fumanoa:

• metsi a hloekileng protozoa ;
• multicellular invertebrates.

Tabeng ea pele re tla kopana le contractile vacuole sebeletsa 'musisi. Ke hore, ba nang le bokhoni ba 'me le monya le ho lokolloa metsi feteletseng. Sehlopha sa bobeli se re ka etsa lintho tse ngata, tse akarelletsang:

• seponche;
• coelenterates;
• ciliated liboko;
• morue.

Ka lintho tse tsena theha vacuoles tshilong ya dijo, tse nang le bokhoni tsa tshilo ya dijo intracellular. Ea bobeli e ka thehoa liphoofolo tse phahameng, empa feela ho itseng lisele tse (phagocytes).
