Brown dimelametsing: tlhaloso e khutšoanyane ea lefapha la

dimelametsing Brown ke tlhamiwe sehlopha sa limela tse phela haholo-holo ka metsi leoatleng. Ho fihlela joale, mefuta e tsebahalang robeli feela, e leng mokhoa oa ho iphetola hoa lintho ba falletse libakeng hloekileng.

Lefapha Kelp: mohaho ona o 'mele

le litho tsohle tsa lefapha la sena re 'mele o multicellular - bokolone le unicellular mefuta ea teng ha ba senoloa. Ha e le boholo, ba ka e fapaneng haholo - joaloka fronds e ka ba nyenyane, 'me fihle limithara tse' maloa ka bolelele. Tsebahalang ea selemo le selemo limela tse leoatleng, empa ho na le ba phela ho fihlela ho lilemo tse 18.

Ha re bua ka sebopeho le sebōpeho sa thalli, ho na le boetse ho na le mefuta-futa e puso. leoatle 'mele e ka akarelletsa ho linaleli tsa lipoleiti, mekotla, crusts kapa lihlahla tse nyenyane. Ho substrate ke tsepamisitsoeng kapa dimela ka tsela tsamaiso e khopo feela kapa rhizoids.

Integument emeloang ke lerako seleng, seo hangata se na le dikarolo tse peli (dikarolo tse tharo 'me e le baemedi ba). Le ka ntle la lekhapetla le sekoahelo sa eona e na le e le hantle ya pectin dintho le e boetse e na polysaccharides sulfated. Lera le ka hare e ne e ena bongata ba masela selulose.

Borax dimelametsing: sebopeho seleng ea

E bath bohlokoa ea lisele hlophisitsoeng ke ho ba teng ha plastids. Baemeli ba sehlopha sena ba dimela, e mong le e seleng e na le palo e khōlō ea lintho tse nyenyane chloroplasts hantle ntshetswa pele. Plastids na lera bane. Ka tloaelo ho, ho lera ka ntle tsa chloroplast lera le fetisa ka reticulum endoplasmic kapa khubu. Ha e le chlorophyll, mona e fana ka liforomo A, C1 le C2.

Ho phaella moo, plastids tsa dimelametsing na fucoxanthin, violaxanthin, zeaxanthin le beta-carotene, e leng e boetse e le tšobotsi ea bohlokoa bakeng sa Plant, taxonomy.

Sele khubung ke e 'ngoe feela, le hoja ho na le ba bang ba selotlolo mefuta. Sehlahisoa se seholo ke sa hrizolaminarin a qenehela e beha ka vacuoles khethehileng kapa ka granules cytoplasmic.

Kelp le ho ikatisa

Baemeli ba lefapha lena le ka ho sa jala vegetatively, ho kopanela liphate le asexually. Ka mefuta e ngata, cloning e phethahatsoa ka ho arola thallus. Empa, ho etsa mohlala, ficus ka bohatong ba 'mele ho na le sehlopha sa lisele tse khethehileng tse ka fetoha e thawed motjha ha ho hlokahala.

Ha e le tshebetso diplobiont, hangata ka ho fetisisa e etsoang ke mokhoa oa ho zoospores. mefuta e 'maloa feela ikatisa ka tsitsitseng mono, kapa tetraspor. Ke tsela, zoospores le diretswe go dira gametes - foromo feela ba hore o teng flagellates kelp.

Ha e le tshebetso ho kopanela liphate, e ka ba o reng:

• Isogamous (peō ea botona le mahe a boholo 'ngoe).
• Heterogamic (diretswe go dira gametes motona le e motšehali ba le diretswe go dira gametes fapaneng).
• Oogamnym (diretswe go dira gametes motona tse nyenyane le mobile, ha basali oogonia lula re ema le fapaneng kholo boholo).

Pota 80s ea lekholo la bo20 la lilemo 'nile ha fumanoa itseng lik'hemik'hale secreted ke' mele nakong ntshetsopeleng thobalano dimelametsing. Sena ke ha ho letho le tšoanang le pheromones, ho ithuta le mafolo-folo e le teng ho fihlela kajeno.

Kelp le baemeli ba ho fetisisa tsebahalang

E mong oa mefuta e ngata tsebahalang e nkoa e tsoekere kelp, kapa leoatle. The dimela o na le dissected kgolo thawed, bolelele ba tsona e ka ba ho tloha limithara tse 1 ho ea ho 14. The thallus lea haha le palo e khōlō ea laminarin. Ho phaella moo, leoatle ho nkoa e tsoa mohloling tsa bohlokoa tsa iodine litareng e. Linaheng tse ling, semela sena e lengoa 'me a sebelisa ka mafolofolo Salads le lijana tse ling. Ea Tal boela a le bulele lithethefatsi sebediswa ea ho phekola mafu a thyroid.

The genus Sargassum e boetse ke tsebahala haholo, hobane ke ka lebaka la ho bo phehellang, telele thalli ea limela tsena metsi Sargasso Sea ka nako eo e ne e le kotsi haholo bakeng sa ho sesa.
