Sei Volvo iri mhando isina kufanana? Chimiro che algae wolvox

Kune dzakawanda zvakawanda zvinoshamisa zvipenyu munyika. Kana mumwe munhu aifunga nezvekuita runyora rwezvishamiso zvinomwe zve microworld, algae volvoix angadai akabatanidzwa mune urongwa urwu.

Green algae

Wolvox is green algae. Izvo zviripo nenzira yekoloni. Sei Volvo iri mhando isina kufanana? Mhinduro yacho inomuka iri nyore: mumwe munhu mumwechete muduku chidha chinenge chiine mapira maviri nemvere.

Masero mashoma anoshamwaridzana nemakumbo matsvuku e-cytoplasmic filaments, izvo zvinobvumira kuti nyika yose ishambire musangano. Vamiririri mumwechete kunze kwemvere uye flagella vanewo zviduku zvitsvuku, izvo zvinonzi ziso.

Kusiyana kwemasero kunopa zvakasiyana kune algae. Ngara imwe neimwe ine kutanga nekuguma, mune mamwe mazwi, North ne South South. Munharaunda yekutanga pane kuwedzerwa kuwedzerwa kwemaziso akavakwa. Izvi zvinobatsira vashandi kuenda kune chiedza. Nokudaro, koni yezvisikwa zveunicellular kunze kunze zvinogona kuburuka kumarudzi akawanda.

Volvox: kuvaka

Pakupindura mubvunzo iwoyo nei volvoix inotumidzwa kune zvisikwa zvisina kuvharwa, zvakakodzera kuti titaure kuti imwe sero inokwanisa kusvika mamita maviri muhupamhi (mumatunhu makuru - kusvika 2 cm), saka inogona kuonekwa nyore nyore neziso rakashama. Akaparadzaniswa nemagetsi anokonzerwa necheplaslasmic filaments.

Algae wolvox urongwa hwakajeka. Nharaunda yacho inenge yakazara nemascus. Masero ose ane maviri flagella, ayo akabatanidzwa pamucheto weperi. Sero rimwe nerimwe riri muchitokisi rinozadzisa basa raro rekudya, kupumhidza uye kubvumira. Chimiro chacho chinogona kunge chakaita soprical, elliptical kana oval. Icho chinyorwa chekunze chinoputirwa nemucheka. Sero rimwe nerimwe rine ziso rimwe mufananidzo wepona pamucheto wokutanga.

Kubereka

Nzira dzekuberekwa mu algae wolvox dzinofadza zvikuru uye dzinofadza. Vanogona kubereka zvose zviri zviviri uye zvepabonde. Pachinyatsoongorora, munhu anogona kuona kuti ruzhinji rwemakoloni rine mukati mawo maitiro akadai anonzi gonads.

Ichi chiratidzo chokuberekwa patsva. Gonads inodyarwa kubva kumasero akakomberedza equator yekoloni. Aya masero anowedzera uye anopfurikidza rutivi rwezvikamu kusvikira aita maduku maduku. Muchiitiko ichi, flagella inowanikwa mukati memutsara mutsva. Kuti abvise, sero rinofanira kuzviratidza mukati mukati.

Wolvox inogona kuzviratidza ivo ivochetewo zvepabonde. Kufanana neAasexual reproduction, masero anokosha anounganidza akaenzana neEquator. Murume nemukadzi vanogadzira makoloni emasero emagetsi akasiyana-siyana.

Spermatozoa inoumbwa nekupesana. Madzimai evanhukadzi zvepabonde haaparadzanisi, asi kungowedzera muhukuru. Zvizhinji zvezvipenyu zvine zvose zvevarume nevakadzikadzi makoloni. Uye zvimwe zvipfeko.

Wolvox uye zuva

Kucherechedza kwemapoka emakoloni pasi pechiedza chemakroscope chiedza chaicho chinoshamisa. Kana iwe ukasiya nzvimbo yakakwana pasi pechifukidziro kuti udimbure, zviduku zvinyoro zvitsvuku zvinowira zvishoma nezvishoma zvichienda kumabvazuva.

Kuwana Volvo iri nyore. Zvose zvavanoda mvura yakachena uye inodziya, inopfuma mune zvinovaka. Nguva yakakodzera yekucherechedza ichando. Kana uchinge watora mimwe michero yakaoma, unogona kuona kuti mumvura yemvura kubva kune "flowering pond" algae ichaswededzwa kuchiedza.

Habitat

Sei Volvo iri mhando isina kufanana? Ngationei. Wolvox ine unicellular structure, haikwanise kuvapo chete, saka inowanzoita maitiro akaenzana ane simba revanhu vanenge 50 000. Haisi pangozi chete, iyo yose inoratidzika. Mariri, maitiro avo anokosha anoitika. Ndicho chikonzero nei volvox inotumidzwa semararamiro ari oga-celled.

Nzvimbo yakanaka yevakadaro yakadaro ndiyo miviri yakachena yemvura. Izvi zvinyoronyoro zvinowanikwa mumadziva, madota uye kunyange mumvura isina kudzika. Nzvimbo dzeAlgae ndeimwe yekare kare panyika. Pasi pemafungiro evasayendisiti, mararamiro akadaro ehupenyu vakange vatungamira mamiriyoni mazana emakore apfuura.

Volvox ndiyo yakanyatsogadzirwa nenyama yemhando yayo. Inoumba globular, ellipsoidal kana ovoid makoloni. Chlorophyll iri mune algal cells, ndicho chikonzero ivo pachavo vanobudisa zvokudya nemafotoynthesis. Sero rimwe nerimwe rinoshanda kuitira kubatsirwa kwaro, uye pamwe chete vanoita sechimwe chinhu.
