Qhov sib txawv tseem ceeb ntawm diatoms thiab dinoflagellates yog tias cov diatoms muaj cov phab ntsa ntawm tes tsim los ntawm silica thaum cov dinoflagellates muaj cov phab ntsa ntawm tes tsim los ntawm cellulose.
Phytoplanktons yog algae uas yog ib leeg-celled eukaryotic hlwb. Muaj ntau hom phytoplankton. Ntawm lawv, diatoms thiab dinoflagellates yog ob hom phytoplankton ntau tshaj plaws uas tuaj yeem pom hauv dej hiav txwv. Lawv muaj peev xwm mus ua photosynthesize, thiab lawv pab rau cov zaub mov tsim nyob rau hauv marine ib puag ncig thiab kuj rau tiam ntawm oxygen.
Diatoms yog dab tsi?
Diatoms, tseem hu ua Bacillariophyta, yog hom loj ntawm phytoplankton. Lawv suav nrog cov hom marine. Lawv yog ib leeg-celled, eukaryotic algae. Cov diatoms tuaj yeem muab faib ua feem ntau raws li lawv cov duab. Muaj ob pawg uas yog centric diatoms thiab pennate diatoms. Centric diatoms muaj cov duab radial symmetrical. Nyob rau hauv sib piv, pennate diatoms qhia ob sab symmetry. Diatoms yog cov ntsuas dej zoo. Lub cim tshwj xeeb ntawm diatoms yog lub xub ntiag ntawm theca. Theca yog cov phab ntsa sab nraud uas npog lub cell. Nws muaj cov silicon dioxide thiab yog lub plhaub zoo li cov qauv. Lub theca muaj ob ntu uas haum zoo rau ib leeg. Lawv yog cov epitheca thiab hypotheca. Theca kuj muaj ntau qhov pores. Lawv zoo li cov kab nyias nyias ntawm phab ntsa sab nraud.
Daim duab 01: Diatoms
Diatoms muaj cov xim xws li chlorophyll thiab fucoxanthin. Cov pigments no muab cov yam ntxwv xim rau diatoms. Muaj ntau tshaj 10,000 hom diatoms xws li Coscinodiscus, Ditylum thiab Lauderia, thiab lwm yam.
Dinoflagellates yog dab tsi?
Dinoflagellates belongs rau phylum Pyrrhophyta. Lawv yog marine, ib leeg-celled, eukaryotic algae uas yog phytoplankton. Lawv muaj cov qauv biflagellated. Lub xub ntiag ntawm ob lub flagella txwv kev txav mus los ntawm cov kab mob no. Yog li ntawd, lawv tsis tshua muaj kev hloov pauv hauv qhov xwm txheej.
Daim duab 02: Dinoflagellates
Lub cell phab ntsa ntawm dinoflagellates muaj cellulose. Muaj cov yam ntxwv tshwj xeeb ntawm dinoflagellates xws li lub peev xwm rau bioluminescence thiab muaj peev xwm tsim cov neurotoxins. Dinoflagellates tuaj yeem ua rau algal blooms thaum muaj tus lej siab. Qhov no yuav ua rau muaj kab mob ntawm cov ntses nyob hauv cov dej hiav txwv no. Yog li ntawd, yog li ntawd, nws yuav ua rau muaj kev hem thawj rau tib neeg cov neeg uas noj cov ntses uas muaj kab mob no. Muaj ntau hom dinoflagellates xws li Ceratium, Peridinium thiab Dinophysis, thiab lwm yam.
Dab tsi yog qhov zoo sib xws ntawm Diatoms thiab Dinoflagellates?
- Diatoms thiab Dinoflagellates yog ib leeg-celled, eukaryotic algae.
- Ob leeg nyob hauv ib puag ncig marine.
- Lawv yog hom phytoplankton.
- Ob leeg muaj chlorophyll thiab lwm yam xim.
- Lawv ua photosynthesis los ua zaub mov.
- Diatoms thiab Dinoflagellates tsim oxygen.
- Lawv muaj peev xwm qhia tau dej zoo.
Dab tsi yog qhov txawv ntawm Diatoms thiab Dinoflagellates?
Ob qhov ntau tshaj plaws phytoplankton pom hauv dej hiav txwv yog diatoms thiab dinoflagellates. Diatoms muaj cov phab ntsa ntawm tes uas muaj silica thaum dinoflagellates muaj cov phab ntsa ntawm tes uas muaj cov cellulose. Qhov no yog qhov sib txawv tseem ceeb ntawm diatoms thiab dinoflagellates. Tsis tas li ntawd, lwm qhov sib txawv ntawm diatoms thiab dinoflagellates yog tias txawm tias cov diatoms thiab dinoflagellates muaj peev xwm ua kom photosynthesize thiab tsim cov pa, cov dinoflagellates tuaj yeem tsim cov neurotoxins thiab muaj peev xwm ntawm bioluminescence, tab sis qhov ntawd tsis muaj nyob hauv diatoms.
Cov hauv qab no infographic nthuav tawm ib sab ntawm kev sib piv los ua qhov sib txawv ntawm diatoms thiab dinoflagellates kom meej.
Summary – Diatoms vs Dinoflagellates
Diatoms thiab dinoflagellates yog hom phytoplankton. Lawv yog ib leeg-celled algae. Diatoms muaj lub theca npog lub cell, uas ua raws li cov phab ntsa sab nraud. Dinoflagellates muaj cov qauv bi-flagellated. Ob leeg muaj peev xwm ua tau photosynthesis thiab muaj pigments. Dinoflagellates muaj cov yam ntxwv tshwj xeeb xws li muaj peev xwm tsim cov neurotoxins thiab muaj peev xwm rau bioluminescence. Qhov no yog qhov txawv ntawm diatoms thiab dinoflagellates.
