Qhov Tseem Ceeb - Liab Algae vs Brown Algae
Algae yog cov polyphyletic loj, cov kab mob photosynthetic uas muaj ntau pawg ntawm hom. Lawv txawv los ntawm unicellular microalgae genera xws li Chlorella mus rau ntau cov ntaub ntawv xws li giant kelp thiab xim av algae. Lawv feem ntau yog dej thiab autotrophic nyob rau hauv cov xwm. Lawv tsis muaj stomata, xylem, thiab phloem uas muaj nyob hauv cov nroj tsuag hauv av. Qhov complex marine algae yog seaweeds. Ntawm qhov tod tes, daim ntawv dej ntshiab tshaj plaws yog Charophyta uas yog ib pawg ntawm ntsuab algae. Lawv muaj chlorophyll ua lawv thawj cov xim photosynthetic. Thiab lawv tsis muaj sterile npog ntawm cov hlwb nyob ib ncig ntawm lawv cov qe menyuam. Liab algae yog ib qho ntawm cov laus tshaj plaws eukaryotic algae. Lawv yog cov multicellular, feem ntau marine algae uas suav nrog ib qho tseem ceeb ntawm seaweeds. Tsuas yog li 5% ntawm cov algae liab tshwm sim hauv dej tshiab. Brown algae yog lwm pab pawg ntawm algae uas yog loj multicellular, eukaryotic, marine algae uas loj hlob nyob rau hauv dej txias ntawm Northern Hemisphere. Muaj ntau hom seaweed tuaj hauv qab xim av algae. Qhov sib txawv tseem ceeb ntawm Red Algae thiab Brown Algae yog tias, nyob rau hauv liab algae, unicellular cov ntaub ntawv yog tam sim no thaum nyob rau hauv xim av algae, unicellular cov ntaub ntawv yog kiag li tsis tuaj.
Red Algae yog dab tsi?
Liab algae txhais tau tias yog eukaryotic, multicellular, marine algae uas tau categorized nyob rau hauv division Rhodophyta. Muaj nyob ib ncig ntawm 6500 txog 10000 hom kab liab algae twb pom thiab lawv suav nrog qee cov seaweeds paub thiab 160 hom ntawm cov dej tshiab (5% ntawm cov ntawv dej tshiab). Cov xim liab ntawm cov algae liab yog vim cov xim phycobiliproteins (phycobilin). Thiab lawv kuj muaj qee cov pigments xws li phycoerythrin thiab phycocyanin. Qee lub sij hawm lawv pom cov xim xiav thiab.
Liab algae ntau yam los ntawm unicellular microscopic cov ntaub ntawv mus rau multicellular loj fleshy daim ntawv. Lawv muaj nyob rau hauv tag nrho cov cheeb tsam ntawm lub ntiaj teb no. Lawv ib txwm loj hlob txuas rau qhov chaw tawv. Herbivores xws li ntses, crustaceans, worms, thiab gastropods yog grazing liab algae. Liab algae muaj qhov nyuaj tshaj plaws kev sib deev lub neej voj voog ntawm tag nrho cov algae. Cov poj niam poj niam cev xeeb tub yog lub npe hu ua 'carpogonium' uas muaj thaj tsam uninucleate uas ua haujlwm li qe. Liab algae kuj muaj qhov projection hu ua 'tricogyne'. Cov txiv neej uas tsis yog-motile gametes (spermatia) yog tsim los ntawm cov txiv neej pw hauv nruab nrog cev hu ua spermatangia. Qee cov algae liab yog cov khoom noj tseem ceeb xws li laver, dulse thiab lwm yam.
Daim duab 02: Liab Algae
"Irish mosh" ua los ntawm cov algae liab yog siv los ua gelatin hloov hauv paj npleg, tshuaj txhuam hniav, thiab ice cream. Cov khoom zoo li gelatin uas tau npaj los ntawm cov kab liab algae xws li Gracilaria thiab Gellidium, yog ib qho tseem ceeb ntawm cov kab mob thiab cov kab mob fungal media.
Brown Algae yog dab tsi?
Cov xim av algae txhais tau tias yog loj, ntau lub cellular, eukaryotic marine algae uas tau categorized raws li kev faib Chromophyta. Brown algae tuaj nyob rau hauv chav kawm Phaeophyceae. Lawv tuaj yeem loj hlob mus txog 50 m hauv qhov ntev. Lawv feem ntau pom nyob rau hauv cov dej txias raws ntug dej hiav txwv continental. Lawv hom xim txawv ntawm xim av tsaus mus rau txiv ntseej ntsuab nyob ntawm seb cov xim ntawm cov xim xim av (fucoxanthin) mus rau xim ntsuab (chlorophyll). Brown algae ntau yam ntawm me me filamentous epiphytes xws li Ectocarpu s mus rau loj loj loj kelp xws li Laminaria (100 m nyob rau hauv ntev). Qee cov xim av algae txuas nrog cov pob zeb ntug dej hiav txwv hauv thaj chaw huab cua (xws li: Fucus, Ascophyllum) lossis lawv ntab dawb (xws li Sargassum). Lawv yug los ntawm ob qho tib si asexual thiab kev sib deev. Ob lub zoospores (motile) thiab gametes muaj ob lub cim tsis sib xws.
Daim duab 02: Brown Algae
Brown algae yog qhov chaw loj ntawm iodine, potash, thiab algin (colloidal gel). Lub algin yog siv los ua tus stabilizer hauv kev lag luam ice cream. Qee hom tau siv los ua chiv thiab qee qhov tau siv ua zaub (Laminaria) tshwj xeeb tshaj yog nyob rau thaj tsam East Asian.
Dab tsi zoo sib xws ntawm Red Algae thiab Brown Algae?
- Ob leeg yog eukaryotic algae.
- Ob leeg muaj marine algae.
- Ob leeg muaj ntau hom kab mob.
- Ob leeg tuaj yeem pom hauv thaj chaw ntug dej hiav txwv thiab txuas rau qhov chaw tawv.

Algae yog hom kab mob eukaryotic ntau tshaj plaws. Lawv kuj muaj prokaryotic cyanobacteria (xiav-ntsuab algae). Muaj unicellular thiab multicellular cov ntaub ntawv ntawm algae. Algae nyob hauv thaj chaw marine ntug hiav txwv zoo li hauv dej tshiab. Algae yog cov loj polyphyletic, cov kab mob photosynthetic. Lawv muaj chlorophyll ua lawv thawj cov xim photosynthetic. Lawv tsis muaj stomata, xylem, thiab phloem uas muaj nyob rau hauv cov nroj tsuag siab dua. Liab algae yog eukaryotic, multicellular, marine algae uas suav nrog qee cov seaweeds. Liab algae kuj pom nyob rau hauv dej tshiab. Brown algae yog loj multicellular, eukaryotic, marine algae hom uas loj hlob nyob rau hauv Northern Hemisphere dej txias. Qhov no yog qhov txawv ntawm liab algae thiab xim av algae.
