Contractile vacuole yaro shanda sumo

Nyaya iyi anotanga muverengi sechivako nyore zvipenyu - kureva, chinotaura pamusoro nemamiriro contractile vacuole kuita excretory (uye kwete chete) basa, vanotaura nezvaireva nyore uye rinotsanangura nzira dzavo kuvapo muna zvakatipoteredza.

Contractile vacuole. pfungwa

Vacuole (kubva vacuole French, kubva muchiLatin shoko vacuus -. Blank), duku idenderedzwa in muna chirimwa uye mhuka masero kana unicellular zvinenge. Contractile vacuole kunyanya muvanhu zvinenge nyore kuti vararame mvura yakachena, Somuenzaniso, pakati protists akadai amoeba proteus, Paramecium caudatum, iro akawana zita rayo yepakutanga kubva Maumbirwe muviri, akafanana chimiro inotsika shangu. Kuwedzera kune izvi nyore, akafanana hurongwa vaakawana masero siyana Freshwater sechipanji, izvo mumhuri spongillidae.

The nemamiriro contractile vacuole. mamiriro ayo

Contractile vacuole ari Kamudzira organelles, izvo anoita ejection yebongozozo mvura kubva cytoplasm. The nzvimbo uye maumbirwo chikwata ichi kunosiyana-siyana mune zvinenge zvakasiyana. The yakaoma dhudhumira-kana tubular vacuoles anonzi Spong, nemvura anopinda contractile vacuole. Nokuda kuti kuramba kushanda wegadziriro anodzokororwa yakagadzikana muchitokisi vhoriyamu. In majemusi vane contractile vacuoles, izvo zvinoumba chikwata yokudzora ari osmotic kumanikidzwa uye kushumirawo kuti tiite kubva mumuviri kuora zvigadzirwa. chete muviri chinosanganisira muchitokisi chimwe chete, izvo zvinozoita anogovera zvose zvakafanira mabasa oupenyu. Vamiririri subkingdoms ichi akadai Paramecium caudatum, Amoeba Proteus, dzimwe unicellular ese ehupfumi yakazvimirira muviri.

Basa nyore zvinenge

Keji anoita zvose anokosha: selection, afemeruke, kushatirwa, kufamba, kubereka, uye muviri. Majemusi vari ubiquitous. Vakawanda dzemarudzi vanogara mugungwa uye yakachena mvura, zhinji vachigaramo nyorova ivhu zvingavhiringidza chirimwa upenyu mitumbi yemhuka zvipuka zvine masero akawanda uye vanhu. Zvakasikwa, kungoita munhu utsanana basa, sezvo vari munyaya riparadzirwe zvinhu, zviri zvokudya mhuka dzakawanda.

Contractile vacuole pa Amoeba Proteus

Amoeba Proteus - mumiririri kirasi rhizomes, usingatangi mukusiyana kune dzimwe nhengo dzomuviri zvachose chimiro. Kutamira inotevera Via prolegs. Zvino ngatitarise kubata avo, chii chiri kushanda contractile vacuole panguva amoebae. Izvi pamwero mutemo osmotic kumanikidzwa mukati muchitokisi rayo. Iye Amoeba Proteus anogona aumbwa chero chikamu muchitokisi. Kuburikidza rokunze Kamudzira mvura kwezvakatipoteredza runoyerera kupinda osmotically. Kuwanda solute muchitokisi amoeba kupfuura mune zvakatipoteredza. Saka, mumwe kumanikidza musiyano mukati zvokutanga masero uye nemhiri. Contractile vacuole Unoshanda amoeba - kubva kubvisa mudziyo mumwe mhando kuti outputs zvakawandisa mvura kubva muchitokisi majemusi. Zvinoyerera zvakatipoteredza Amoeba proteus vaunganidza unogona mvura chero mugove muviri pamusoro.

Kwakadaro kushanda contractile vacuole unogamuchirwa nokuda zvinenge nyore kuti vararame mvura yakachena. In parasitic uye zvomumvura siyana kuti kurarama mumamiriro ezvinhu umo osmotic kumanikidzwa kuri kupfuura mumvura yakachena, izvi chinyakare mano vari kuderedzwa kana chaizvo kashoma kazhinji vasipo. Around contractile vacuoles ari kupfuura nyore zvinenge dzichiitika mitochondria kuendesa simba rokuita osmotic basa.

Kunze osmoregulatory anoita rinokosha kushanda afemeruke, semubairo osmosis anosvitsa kuuya mvura kudaro oxygen. Chiizve ndiyo kushanda contractile vacuole? Just kuita excretory basa, kureva nemvura yaiwana metabolic zvigadzirwa avo ezvinhu.

Mweya kusarudzwa osmoregulation mu ciliates shangu

Muviri nyore yakafukidzwa pedyo gobvu goko, iro rine dzose chimiro. Rinodya utachiona, uye algae, kusanganisira zvimwe majemusi. Ciliates muviri zvikuru kunzwisisa pane imwe amoeba mamiriro. Muchitokisi, pamberi uye neshure neshangu dziri mbiri contractile vacuoles. In chikwata ichi distinguishable tangi uye tubules duku dzakawanda. Contractile vacuole nguva, nemhaka mamiriro ichi (microtubule), ari yakamisirwa nzvimbo muchitokisi.

The chikuru kushanda contractile vacuoles muupenyu mumiririri nyore - osmoregulation, sezvo anobvisa kubva masero zvakawandisa mvura, iyo anopinda sero nokuda osmosis. Chokutanga, ari kuzvimba kwakanga vaitungamirira Mipata, ipapo mvura pumped kubva kwavari chaiyo tangi. Dura ipfupi, anosiiwa kwaizoita migero kuburikidza pores mvura pauri. Muchitokisi, ciliates zviviri contractile vacuoles, izvo, akavapindurawo, vanoita zvinopesana. Nokuda nokushanda maviri mano dzakadaro akagovera chichiitika. Uyezve, mvura iri ichi- rinoparadzirwa kuburikidza mabasa contractile vacuoles. Vari rave compressed uye marwadzo kakawanda kunobva ambient tembiricha.

Saka, panguva nenzvimbo tembiricha (18 - 20 Celsius), kakawanda kuti sunga ose vacuoles, maererano masekonzi zvimwe 10-15. Uye akapiwa kuti zvakasikwa dzinogarisana shangu dziri chero mvura yakachena pamwe akamira mvura uye kuvapo mairi ine makemikari nyaya kuora, tembiricha yomunhu svikiro pa madhigirii anoverengeka dzinosiyana-siyana zvichienderana nenguva yegore uye saka kakawanda sunga vanogona kusvika 20-25 seconds. Mumwe awa contractile vacuole nyore muviri anokwanisa uzvirasire masero ari mari mvura. kuenderana ukuru hwaro. Vanounganidza zvinokurisa undigested zvokudya, metabolic magumo zvigadzirwa, unogonawo kuonekwa okisijeni uye senitrogen.

Wastewater kurapwa majemusi

Mugumisiro wokufambisa nyore zvinhu vokuitirwa zvikuru. In reservoirs nokuda anoburukira tsvina, ruminant akawanda utachiona. Somugumisiro, kune siyana majemusi izvo zvinoshandiswa chikafu uye utachiona izvi, uye nokudaro pave yepanyama okuchenesa reservoirs.

mhedziso

Pasinei nyore maumbirwo zvipenyu izvi chimwe celled, muviri iyo inoumbwa sero rimwe chete, asi anoita mabasa yose muviri, inoshamisa kujairana zvakatipoteredza. Unogona kuonekwa munzira nemamiriro contractile vacuole. To musi, hatina kare zvakaratidza zvikuru muna nyore hunhu hwavo kuita ichitanga yacho.
