Chlamydomonas: mbali ya kapangidwe ndi gulu

Kwa nthawi yaitali, asayansi sanathe kudziwa udindo taxonomic wa chamoyo anadabwa, tikambirana nkhani. Ndipotu ndi unicellular kutha mwachangu kusuntha, mutanyamula kunja ndondomeko ya photosynthesis. Ndipo dzina lake ndi chidwi. Iwo chlamydomonas.

Dipatimenti Green algae

Motero, pomaliza, asayansi kuona kuti chamoyo ndi nthumwi ya ufumu mbewu, ngati angathe palokha kaphatikizidwe zinthu organic m'kuunika limapangidwa plastids wobiriwira mu chipinda.

Chlamydomonas (chithunzi limasonyeza nkhani za selo) limabweretsa gulu la algae wobiriwira, amene nthawi zambiri imakhala mitundu 15 chikwi. Angapezeke mu matupi ang'onoang'ono madzi oyera. Nthawi zambiri iwo bwino kutenthetsa. ndere Izi si wovuta kwambiri za ukhondo wa madzi Choncho, propagates mwakhama malo akuda.

Chlamydomonas: Cell kapangidwe

Ngakhale kuti algae ikuyimiridwa ndi chimodzi chokha selo tosaoneka kukula, izo ziyenera dongosolo mwachilungamo zovuta, adzatha kuchita ndondomeko zonse zofunika pa moyo.

Chlamydomonas selo uli ndi chowulungika, ndipo nthawizina pyriform. Mphepete ake kutsogolo ili michirayo imakhala yosiyanasiyana awiri. Izi kayendedwe organelle. Ma chipolopolo limapangidwa pectic zinthu ndi glycoprotein. chakudya izi zimapatsa mphamvu wosanjikiza lakunja la chamoyo.

Ngati maselo ena ili mkati cytoplasm wa - mkati theka-madzi okhutira, amene amapereka mawonekedwe ndi kuchita kagayidwe. Ambiri algae amatenga chloroplast. Izo cupped. Nthawi zina amatchedwanso chromatophores. Ndi pyrenoids - mapangidwe chikhalidwe mapuloteni, kuzungulira amene waikamo zakudya. Komanso cytoplasm kumawala-tcheru diso - mtundu wa "Kulingalira limba". Njirayi imatchedwa manyazi.

Ntchito contractile vacuole

Chlamydomonas - kukhala m'madzi. Choncho, nthawi zonse zofunika kuchotsa madzimadzi wolowera selo kwa chilengedwe. Izi zachitika mwa organelles wapadera - contractile vacuole. Chifukwa madzi zimalowa ndi Chlamydomonas? Chinthu ndi mchere zili mu madzi ndi zambiri apamwamba kuposa selo yokha. Malinga ndi malamulo a sayansi, ndipo utuluke madzimadzi ku dera ndi ndende apamwamba mu m'munsi. Ie mu algae selo. vacuole Contractile kuthetsa algae kwa madzimadzi owonjezera.

NKHANI ntchito foni

Mwa njira ya kudya ndi chlamydomonas mixotrophy. Izi zikutanthauza kuti kuwala amatha photosynthesis. Koma sitili pa zinthu zofunika kaphatikizidwe zinthu organic amakhala heterotrophs. Izo basi imayamwa zakudya wokonzeka kuti m'madzimo.

Chosowa resets kayendedwe chinyezi selo organelle ndi njira zonse zofunika ali inaimitsidwa. Choncho amanyamula sinali bwino chlamydomonas.

Ndere kubalana kumachitika m'njira zambiri. Nthawi zambiri - asexual. Mu nkhani iyi, selo adasandulika. Iwo resets ndi michirayo imakhala yosiyanasiyana, kotero gululi kumakhala kovuta. Mkati maselo kupanga zoospores. chiwerengero chawo lingayambire pakukhala 2 8. Ndi motile maselo. Iwo anabwera kuchokera chamoyo ndi akuchikazi kukula ndi kuyamba moyo paokha. Zimenezi ndi kwambiri - izo akubwerezedwa tsiku lililonse. Pamene mikhalidwe yabwino kwa moyo wa Chlamydomonas, izo zimapita kwa kubereka. Choncho anapanga mkati gametes ake - maselo nyongolosi. Iwo amapita ku madzi pa confluence a awiriawiri. Chifukwa, mapangidwe zygote lapansi. Mu chikhalidwe ichi, iwo ali pamaso pa isanayambike zinthu zabwino. Ndiye zygote wogawanika, ndipo aliyense wa iwo ndipamene 4 achikulire.

Mtengo wa Chlamydomonas mu chikhalidwe ndi moyo wa anthu

Nthumwi za algae wobiriwira kalekale nkhani za kafukufuku zasayansi. Chikhalidwe cha mtengo wake chifukwa cha maluwa madzi osaya patsogolo. Kalikiliki ndondomeko izi zimachitika m'dzinja ndi masika. Izi nthawi kubalana kwambiri mwamphamvu algae.

Monga zokhala ndi selo imodzi wobiriwira ndere zing'onozing'ono zolengedwa chlamydomonas, ali ndi dongosolo m'malo zovuta kwambiri m'thupi kuti zikhale zotheka linakhalapo mu malo m'madzi.
