Mbali kandalama ndi kapangidwe ka Chlamydomonas

Chlamydomonas - limodzi tating'ono chamoyo, wakuti amene ali pamaso pa awiri apical michirayo imakhala yosiyanasiyana. Ndi mtundu wa algae wobiriwira amene amakhala mwa madzi patsogolo ndi nthaka yonyowa, komanso atsopano kapena nyanja madzi. Kapangidwe ka Chlamydomonas angapo mbali. Mwa njira imeneyi ion kuti adamulowetsa malinga mwachindunji kulinga kukuwunika, ndi wofiira photosensitive diso ndi zovuta dongosolo zolimbana.

Chlamydomonas: onse mudziwe

Ndi mtundu wa chakudya ambiri a mitundu ali ziyenera phototrophic. Koma ena facultative heterotrophs, amene akhoza kukula mu mdima, ntchito monga magwero mpweya nthochi. Mu kafukufuku wakapangidwe kazachilengedwe ake ndi mafoni unicellular algae, kawirikawiri chowulungika. Mpanda selo tichipeza glycoprotein a. Chlamydomonas kubereka onse pogonana ndi asexually.

Pali pafupifupi 150 mitundu. Chlamydomonas proliferates mwachangu chilengedwe chinyezi, komanso mankhwala ammonium madzi kulemera. Features ya kapangidwe ka Chlamydomonas monga kupezeka kwa inki. Matope wobiriwira mtundu wa madzi m'mavuto chifukwa kukhalapo kwa zikwi tizilombo flagellated. Bright wofiira pigment ku mtundu kumathandiza kuti kudetsa malo mtundu ofiira kapena pinki. Ena mitundu zimapezeka malo ambiri zosayembekezereka, monga madzi amchere nyanja.

Kapangidwe ka Chlamydomonas

Mu msana khomo lachiberekero ndi michirayo imakhala yosiyanasiyana awiri, kutenga chiyambi chake kwa mbewu woyambira ili mu cytoplasm lapansi. zapansi awo contractile vacuole. Kapangidwe ka maselo Chlamydomonas akusonyeza pamaso pa chloroplast chikho woboola pakati, komwe ndi selo phata. Pali aumbike ku mankhwala a dzuwa wowuma ndi mapuloteni, wazunguliridwa ndi mbewu ya wowuma. Peephole mu malo alipo kutsogolo kwa chloroplast lapansi. Amakhala ndi awiri kapena atatu, kapena zochepa kufanana mizere ya linearly anakonza m'malovu mafuta.

Features dongosolo la

Mu mbali yake vegetative lake lili dongosolo lophweka. kukula kwake zimasiyanasiyana pakati 0,02 mm. Mukachipinda ali ozungulira, ellipsoidal, cylindrical kapena mawonekedwe peyala. Iwo ali ndi chizolowezi zisonga pa kumaso. Kapangidwe Chlamydomonas selo limapangidwa ndi woonda kunja khoma, awiri michirayo imakhala yosiyanasiyana, komanso awiri vacuoles contractile udindo kupuma ndi excretion. The lalanje-wofiira pigment kapena eyelet (manyazi) kusungidwa mu khoma selo chachikulu, ndi kuchita ntchito ya munthu wosazindikira monga amakhudzidwa kwambiri kuwala. Ena mitundu akhoza kukhala pamaso mawanga diso awiri kapena atatu. mkulu cupped chloroplast, limene lili mkati pakati lili mbali linafalitsidwa kwambiri za thupi cytoplasm lapansi.

Kodi dongosolo selo ndi asexual kubereka?

Chlamydomonas dongosolo amaloŵamo ena kusintha pa magawano selo. Asexual kubalana kumachitika m'njira zotsatirazi: chilengedwe cha zinthu zabwino anapanga zoospores selo chimakhala chili, michirayo imakhala yosiyanasiyana chikopa kapena anataya kutha komanso vacuoles contractile protoplast anagawa longitudinally pawiri, omwe nawonso, ndi mbali 2. Choncho, selo lililonse umabala 2 16 Ine formations ofanana. Pang'onopang'ono, anthu aang'ono kuoneka nyumba yonse khalidwe la algae wobiriwira: michirayo imakhala yosiyanasiyana, vacuoles, ndi zina zotero. Aliyense wa iwo akufotokozera mu mtengo watsopano. Zimenezi kulekana akubwerezedwa mawola 24. Choncho pofika kumapeto kwa sabata kuchokera ku mtengo umodzi mayi limatulutsa miliyoni anthu anapanga.

Features wa kubereka

Pa kugonana kubalana selo protoplast divisible ndi 16, 32 kapena ngakhale 64 flagellates gametes kuti akhoza kukhala uncoated kapena akaidi khoma selo. Kugonana maselo angakondwere nazo zosakaniza awiriawiri kupanga zygote. Chifukwa, iwo adzakhale anabwerera ndi michirayo imakhala yosiyanasiyana, n'kupanga mpanda wandiweyani padziko cytoplasm ndi limalephera pansi pa mosungiramo chitukuko zina. Mu njira imeneyi ndi khola kutentha ndipo adzapulumuka ngakhale mosungiramo uphwetsa. Zoospores ndi gametes ndi morphologically ofanana. Akusiyana okha kukula ndi khalidwe. kusiyana zimachitika chifukwa mayunitsi zambiri za foni mayi pa mapangidwe gametes. Choncho, anthu ang'ono kutaya luso lawo kudzimvera ang'onoang'ono.
