Detachment Green algae: kufotokoza mwachidule

Pakali pano, wobiriwira algae imatengedwa gulu yaikulu, yomwe kuli mitundu pafupifupi 20 chikwi. Zikuphatikizapo zokhala ndi selo imodzi zamoyo zonse ziwiri, ndi mitundu ndi atsamunda, komanso zomera ndi multicellular Thallus lalikulu. Pali nthumwi kuti moyo mu madzi (mchere ndi watsopano) komanso zamoyo kusinthidwa kuti apulumuke dziko zinthu achinyezi.

Dipatimenti Green algae: kufotokoza mwachidule

Mbali yaikulu ya gulu ili mtundu wawo chiwembu - kwa mitundu yonse ya khalidwe mtundu wobiriwira kapena enaake achikasu. Ichi ndi chifukwa maselo waukulu pigment - chlorophyll.

Monga tanenera kale, dipatimenti Chili oimira chosiyana. Pali unicellular ndi atsamunda mitundu, komanso zamoyo multicellular ndi lalikulu, kusiyanitsidwa Thallus. Akuluakulu unicellular kusuntha ntchito michirayo imakhala yosiyanasiyana, multicellular, kawirikawiri Ufumuyo pansi kapena moyo mu ndime madzi.

Ngakhale pali zamoyo ndi maselo umboni, ambiri likhale khoma selo. Waukulu structural zikuluzikulu za khoma selo ndi mapadi, amene poyamba imatengedwa zofunika mwadongosolo khalidwe.

Chiwerengero, kukula ndi mawonekedwe a chloroplasts muchipindachi amakhala osiyanasiyana malingana ndi mtundu wa mbewu. The pigment chachikulu ndi wotchedwa chlorophyll, makamaka, ndi b mawonekedwe. Koma carotenoids mu plastids ali makamaka beta-carotene ndi lutein, komanso wochepa neosantina, zeaxanthin ndi violaxanthin. N'zochititsa chidwi kuti maselo a zamoyo ena a kwambiri chikasu kapena lalanje mtundu - ichi ndi chifukwa kudzikundikira carotenoids ndi chloroplast.

Ena zokhala ndi selo imodzi wobiriwira algae ndi dongosolo yeniyeni - diso kuti Yankho kuyatsa buluu ndi wobiriwira sipekitiramu.

The mankhwala ikupezeka ndithu granules wowuma zomwe zili ambiri mu plastids lapansi. Only ndi nthumwi zochepa za dongosolo m'malo zinthu ndi waikamo mu cytoplasm lapansi.

Dipatimenti Green algae: njira kuswana

Ndipotu, kwa oimira gulu ili yodziwika ndi pafupifupi njira zonse zotheka la kubalana. Vegetative kubalana kumachitika ndi kugawikana selo (unicellular oimira yopanda mipanda khungu), kugawikana Thallus (njira imeneyi ndi khalidwe la mitundu multicellular ndi atsamunda). Mu mitundu ina tinatake tozungulira yeniyeni anapanga.

Asexual kubalana ndi umaimiridwa ndi njira zotsatirazi:

• zoospores - michirayo imakhala yosiyanasiyana maselo amatha kuyenda yogwira;
• aplanospory - saona zinthu mkangano flagellar zida, koma bwino anayamba contractile vacuole; maselo sangathe kuyenda yogwira;
• autospores - mtundu wa mkangano chikukhudzana kwenikweni anatengera chilengedwe. Mu njira imeneyi, thupi kudikira mu nthaka youma, ndipo zinthu zina chokhwima.

kubereka akhoza zosiyanasiyana - izo oogamy ndi heterogamy ndi hologamiya ndi isogamy ndi conjugation.

Detachment Green algae: mapangidwe a ena oimira

gulu oyimirira ambiri otchuka a dziko mbewu. Mwachitsanzo, zokhala ndi selo imodzi algae Spirogyra ndi Chlorella ali m'gulu kumuwombera lapansi.

Chlamydomonas - amamudziwa mtundu wa algae wobiriwira, zomwe ndi zofunika zothandiza. gulu Izi zikuphatikizapo zinthu unicellular ndi lalikulu chromatophores wofiira diso, lomwe lili ndi inki. Iwo chlamydomonas zimayambitsa "ukufalikira" madzi Madamu, maiwe ndi m'chere zokhala m'malo owetera. Mu kukhalapo kwa dzuwa organic zinthu umatulutsa photosynthesis. Komabe, izi chamoyo akhoza kuyamwa zinthu ku malo akunja. Choncho Chlamydomonas zambiri ntchito ayeretsedwa ndi madzi.
