Moss vs Algae
Txhua yam kab mob tau muab faib ua tsib lub tebchaws. Cov no yog Monera, Protectista, Fungi, Plantae thiab Animalia. Kev faib yog ua raws li 3 yam. Cov no yog cov koom haum cellular, kev npaj cov hlwb, thiab hom khoom noj khoom haus. Cellular koom haum yog seb lawv yog eukaryotic lossis prokaryotic. Cell kev npaj yog seb lawv yog unicellular, multicellular, nrog los yog tsis muaj tseeb cov ntaub so ntswg sib txawv thiab lwm yam. Hom kev noj haus yog seb lawv yog autotrophic los yog heterotrophic. Kingdom Protectista suav nrog algae, protozoans, oomycota thiab slime pwm. Kingdom plantae muaj xws li bryophytes, pterophytes, lycophytes, cycadophytes thiab anthophytes. Hauv lwm lo lus, algae tuaj nyob rau hauv lub nceeg vaj Protoctista thiab mosses tuaj nyob rau hauv lub nceeg vaj plantae.
Algae
Muaj plaub phyla hauv tebchaws Protectista uas suav nrog ntau hom algae. Cov no yog phylum Chlorophyta uas suav nrog ntsuab algae, phylum Phaeophyta uas suav nrog xim av algae, phylum Rhodophyta uas suav nrog liab algae, thiab phylum Bacillariophyta, uas suav nrog diatoms. Algae yog ib pawg loj ntawm cov kab mob (protoctistans) uas tseem ceeb heev lom neeg. Lawv feem ntau yog photosynthetic eukaryotes nyob hauv dej. Algae tuaj yeem pom nyob rau hauv dej hiav txwv thiab dej tshiab. Lub cev ntawm algae tsis muaj stems, nplooj los yog keeb kwm. Yog li ntawd, lawv lub cev hu ua thallus. Algae tau muab faib ua ntau hom phyla raws li hom ntawm lawv cov xim photosynthetic. Tag nrho cov phyla no muaj qee qhov kev coj ua zoo ib yam. Yuav luag txhua tus zoo yoog rau lub neej hauv dej. Lawv qhia txog kev sib txawv loj ntawm cov tswv cuab hauv cov ntsiab lus ntawm qhov loj thiab daim ntawv. Lawv suav nrog unicellular, filamentous, colonial, thiab thalloid cov ntaub ntawv.
Mosses
Phylum bryophyta suav nrog cov av yooj yim tshaj plaws. Nws yog xav tias lawv tau hloov zuj zus los ntawm ntsuab algae. Muaj ob chav kawm tseem ceeb hauv phylum bryophyta. Cov no yog cov chav kawm Hepaticae uas suav nrog cov kab mob siab thiab cov chav Musci, uas suav nrog mosses. Cov pab pawg no tsis zoo rau kev ua neej nyob hauv av. Lawv raug kaw rau qhov chaw moist, shady. Cov nroj tsuag no tsuas yog ob peb centimeters siab. Alternation ntawm tiam yog tam sim no qhov twg gametophyte yog dominant. Hauv chav kawm Musci lossis mosses, gametophyte tau sib txawv rau hauv 'stem' thiab 'nplooj'. Nplooj yog teem spirally nyob ib ncig ntawm lub qia nyob rau hauv peb kab. Gametophyte yog anched rau hauv av los ntawm rhizoids. Cov rhizoids no yog multicellular. Cov sporophyte loj hlob txuas mus rau poj niam gametophyte. Lub sporophyte ib nrab nyob ntawm tus poj niam gametophyte. Spore dispersal yog los ntawm ib tug elaborate mechanism. Nws nyob ntawm tej yam mob qhuav, thiab tsis muaj elaters.
Dab tsi yog qhov txawv ntawm Algae thiab Mosses?
• Algae belongs rau phylum Chlorophyta, Phaeophyta, Rhodophyta los yog Bacillariophyta ntawm lub nceeg vaj Protoctista, whereas mosses belongs rau chav kawm Musci ntawm phylum Bryophyta ntawm lub nceeg vaj Plantae.
• Txawm hais tias algae tsis muaj qhov tseeb lub cev sib txawv ntawm cov hauv paus, stems, thiab nplooj, mosses muaj qee qhov sib txawv ntawm cov qia thiab nplooj.
• Mosses yog anched rau hauv av los ntawm rhizoids thiab algae yog anched rau lub substratum los ntawm ib tug qauv hu ua tus tuav.
• Alternation of generation is present in mosses, and there is no alternation of generations in algae.
• Feem ntau ntawm cov algae nyob hauv marine los yog dej tshiab, whereas cov mosses nyob hauv moist, shady terrestrial chaw nyob.
• Muaj peev xwm muaj unicellular algae tab sis yeej tsis unicellular mosses.
