Chlamydomonas: zvinhu zvehutano uye sangano

Kwemazuva mazhinji masayendisiti haana kugona kutsanangurira nzvimbo yakagadziriswa yehupenyu hunoshamisa, iyo ichakurukurwa munyaya yedu. Mushure mezvose, ichi chisikwa-chisikwa chine simba chinokwanisa kushingaira kufamba, pachinenge chichiita shanduro ye photosynthesis. Hungu, uye zita rayo rinofadza. Ichi chlamydomonas.

Dhipatimendi reGreen Seaweed

Somugumisiro wekufunga kwenguva refu, masayendisiti akasvika pakugumisa kuti chimiro ichi chiri mumiriri weumambo hwemuti, sezvo unokwanisa kuzvimiririra pamwe yezvinhu zvakasikwa mune chiedza uye ine plastids yakasvibirira muchitokisi.

Chlamydomonas (chinyorwa chinoratidza zviri mukati memusero) ndeyeboka reGreen algae, iro rose rinosvika kusvika zviuru gumi nemarudzi. Iwe unogona kumusangana naye mune zviduku zvitsva zvemvura. Kazhinji kazhinji vanopisa zvakanaka. Iyi alga haisi iyo inofadza kwazvo kuchena kwemvura, saka inowanda yakawanda munzvimbo yakasvibiswa.

Chlamydomonas: cell structure

Pasinei nokuti izvi zvinyorwa zvinomiririrwa nesero rimwe chete rezvinyorwa zvisinganyanyi kukosha, rine hurongwa hwakanyanya hwakaoma hunokwanisa kuita zvose zvinodiwa zvebasa rinokosha.

Chlamydomonas ine chevha yakasviba, uye dzimwe nguva iine pear. Iko kune mavara maviri maviri pamusana wayo. Ichi chikamu chikamu. Semu membrane yesero ine pectin zvinhu uye glycoprotein. Aya mahaidhaidhadhi anopa simba kumucheto wokunze wemuviri.

Kufanana nedzimwe masero, mukati imomo cytoplasm - mukati memiti-mumvura zvinogadzirwa, kupa chimiro uye kushandiswa kwemagetsi. Zvizhinji zvezverwa zvinotorwa ne chloroplast. Iine mukombe wakaita sekapu. Dzimwe nguva inonziwo chromatophor. Inowanikwa pyrenoid - kuumbwa kwemapuroteni chaiwo, kwakapoteredza michina inowanikwa. Uyewo mu cytoplasm ndeyeziso refotoensitive - rudzi rwe "organ organ". Inonzi kushorwa.

Mabasa emaguoles anopinda

Chlamydomonas mvura inogaramo. Saka, inoramba ichida kubvisa mvura inopinda muchitokisi kubva mumhepo. Izvi zvinoitika kuburikidza nekubatsirwa kweguniti rinokosha - contractile vacuoles. Nei mvura inopinda chlamydomonas? Chinhu chacho ndechekuti zvinyorwa zvesarti mumuviri wemvura, sekutonga, zvakakwirira zvakanyanya kupfuura muchitokisi pachako. Maererano nemitemo yefizikiki, iyo mvura inobvawo kune imwe nzvimbo ine yakakwirira yakanyanya kusvika kune duku. Ie. Chengetedza muenzaniso wemiti yemiti. Izvo zvinogadziriswa zvinogadziriswa zvinotapira zvinokonzera vashandi kubva pane zvinodhaka zvakanyanya.

Zviratidzo zvesero rinokosha basa

Nenzira yekudyisa chlamydomonas isanganotroph. Izvi zvinoreva kuti muchiedza icho chinokwanisa kupikisa photosynthesis. Asi kana pasina mamiriro ezvinhu anodiwa ekugadzirwa kwezvinhu zvakasikwa, inova heterotroph. Iyo inongoyanganisa mishonga yakagadzirwa yakagadzirwa iri mumvura.

Nekushaya kwanyoro, sero rinokonzera organelles rekufamba, uye zvose zvinotora basa rinokosha zvinomiswa. Saka inobvumira mitemo isingagamuchirwi ye chlamydomonas.

Kuberekwa kweAlgae kunowanikwa nenzira dzakasiyana. Kazhinji kazhinji - asexual. Muchiitiko ichi, sero inoshandurwa. Anodonha flagella, saka chikamu hachibviri. Mukati memusero, zoospores zvinoumbwa. Nhamba yavo inogona kuenzana kubva pa2 kusvika ku8. Aya ndiwo masero efoni. Vanosiya muviri wemubereki, kukura uye kutanga hupenyu huripo. Iyi nzira yakanyanya kwazvo - inodzokororwa maawa makumi mana nemaviri. Apo mamiriro ezvinhu asina kunaka kune hupenyu hwe chlamydomonas, inoenderera pakuita zvepabonde. Panguva imwecheteyo gametes inoumbwa mukati maro - masero epabonde. Vanopinda mumvura, kwavanobatana vari vaviri. Somugumisiro, zygotes dzinoumbwa. Munyika iyi ivo vari mberi kwekuuya kwemamiriro akanaka. Zvadaro zygotes dzinoparadzanisa, uye mumwe nomumwe wavo anoita vanhu vakuru 4.

Kukosha kwe chlamydomonas mune zvakasikwa uye upenyu hwehupenyu

Uyu mumiriri wegreen algae ave kwenguva refu ave chinhu chinotsvakurudza ma laboratory. Muzvisikwa, kukosha kwayo kunobatanidzwa nekutumbuka kwemvura isina kudzikama yemvura. Iyi nzira inonyanya kushanda mukuvhuvhura uye mutambo. Iyi ndiyo nguva yenguva yakakura yekugarisa vana.

Kuva chisikwa chisina kuchena, che alga yega ye chlamydomonas ine hurongwa hwakanyanya hwakaoma uye hutano hwebasa rinokosha rinoita kuti zvikwanise kuvapo mumamiriro emvura.
