Vacuole - ichi ... kushanda muchitokisi vacuoles

Nhasi tichataura pamusoro chii vacuole. Ndiyo imwe chezvinonhuwira muchitokisi, kureva organelles. Organelles kana organelle - nayo inoramba anoumba masero, ekupedzisira, uyewo, ndivo hwaro zvose tichigara.

Kutaura zvazviri, nyika haisi zvahunoratidzika pakutanga kuaona. Inofanira atore maikorosikopu, uye nyika yedu zvichachinja zvikuru. The kuziva yokutanga nenhumbi ichi zvinoitika chesekondari achiri. Vadzidzisi vanofanira kuva nechokwadi kuti kupa hurukuro pamusoro nemitemo kushandiswa maikorosikopu kuitira kudzivisa zvisingafadzi zviitiko pa yakadaro inofadza basa. Pashure penguva pfupi digression kukuudzai kuti ndiye vacuole. Ichi nyaya yedu huru.

vacuole

Ngatitange aine tsananguro chikamu. Vacuole - ichi organelle (odnomembranny). Inogona kuwanika mumasero eukaryotic. Pakarepo yokusuma zvishoma tsananguro: kuti eukaryotes - foni ine core. The yokupedzisira anosiiwa ari cytoplasm pedyo kaviri membrane. The kukosha tsanga riri guru, kuti rine morekuru reDNA.

Saka vacuole - ichi organelle anokwanisa kuita zvakawanda siyana anoitwa (iyo tinoti gare gare). Sei organelles aya aumba? Zvakatanga kubva provakuoley, sezvo vanoonekwa kwatiri muchimiro Kamudzira vesicles.

Zvakakosha kuziva uye chii unogona vacuoles zvose mapoka mapoka maviri:

• mumatumbu;
• pulsating.

Dzimwe nguva pulsating vacuoles anonzi contractile. Vanobatsira kubvisa kuora zvigadzirwa. Chiizve anoita ichi vacuole kushanda, tichakurukura gare gare.

In chirimwa masero, vacuoles kugara vanopfuura hafu vhoriyamu, dzimwe nguva havana batanidza chimwe organelle guru, iro nokure kukura zvavo.

Vose vacuole Kamudzira iri shoma, inonzi - tonoplast. Inside tinogona kuwana sero muto. Yokupedzisira ine zvinotevera:

• mvura;
• monosaccharides;
• disaccharides;
• tannins;
• makabhohaidhiretsi;
• nitrates;
• phosphates;
• chlorides;
• Organic acids uye zvimwe zvinhu.

mabasa

Zvino isu kupa kuti govera inokosha inokurukurwa nesu organelles mabasa. Vacuole, yatiri nyorai mabasa anogona kutora sero nzvimbo kubva 5 kusvika 90 muzana. Rakavapa napo apo organelle uyu.

Panyaya mhando masero ari chirimwa pane zvakawanda, uye mhuka vane nguva organelles. Hatina vakati kare kuti, zvichienderana nzvimbo vacuole anogona mabasa akasiyana-siyana. Asi isu kumboremekedza zvihombe maviri:

• ukama organelles;
• senga basa.

chirimwa sero

zvino isu anozodzidza uwane kudzidza organelles mu chirimwa mumasero. Cell vacuole - iri kwayo chikuru zvinoriumba. Ngativerengei zvinyore sei:

• vacuole absorbs mvura;
• Inobvisa zvinokuvadza;
• mune zvimwe zviitiko vacuoles zvakabudisa samafuta muto;
• munyaya muitiro anotsemura tsaru organelles;
• kuunganidza muviri.

Sezvaunogona kuona, izvi organelles basa zvechokwadi chikuru. Ko isu kutaura kuti vanokwanisa kuputsa tsaru organelles, kureva kuita mashandiro lysosomes. Nokudaro, vacuole anogona makemikari zvaidikanwa hydrolysis anotevera zvinhu:

• mapuroteni;
• mafuta;
• makabhohaidhiretsi;
• nucleic acids;
• phytohormones;
• akadaro kugadzirwa, uye zvichingodaro.

Ivo dzinoitawo nedanho photosynthesis, izvo zvinokosha kwete chete nokuda zvinomera asiwo vamwe zvinenge.

zooblast

Vacuoles dzinogona kuwanikwa pana:

• Freshwater majemusi ;
• zvipuka zvine masero akawanda invertebrates.

Muchiitiko chokutanga ticharamba kundosangana contractile vacuole kushumira gavhuna. Ndiko, ivo vanokwanisa rokutora uye kusunungura mvura nekusazvidzora. Boka rechipiri hatigoni zvinenge zvakawanda, kusanganisira:

• sechipanji;
• coelenterates;
• ciliated Makonye;
• dzemugungwa.

In zvinenge izvi zvinoumba zvomudumbu vacuoles, izvo vanokwanisa intracellular kugaya. Ekupedzisira anogona aumbwa mhuka yakakwirira, asi chete mune zvimwe masero (phagocytes).
