Qhov sib txawv tseem ceeb ntawm chrysophytes thiab euglenoids yog tias chrysophytes yog ib pab pawg ntawm Protista uas cuam tshuam nrog diatoms thiab desmids, thaum euglenoids yog ib pawg Protista uas koom nrog ib leeg-celled algae uas tsis muaj cellulosic cell phab ntsa.
Kingdom Protista suav nrog cov kab mob unicellular eukaryotic. Feem ntau ntawm cov protists yog photosynthetic. Lawv qhia ob qho tib si cog zoo li tsob ntoo thiab tsiaj zoo li cov yam ntxwv. Ntau hom yog cov kab mob hauv dej, thiab lawv yog cov tsim khoom tseem ceeb ntawm cov dej hauv dej. Lawv muaj cilia lossis flagella. Slime pwm, protozoa, euglenoids, dinoflagellates thiab chrysophytes yog tsib pawg loj ntawm lub nceeg vaj Protista. Chrysophytes suav nrog diatoms thiab golden algae. Lawv tsim ib qho tshwj xeeb carbohydrate hu ua chrysolaminin. Euglenoids suav nrog feem ntau cov dej tsis qab algae. Lawv tsis muaj cellulosic phab ntsa, tab sis lawv muaj pellicle thiab eyepot.
Chrysophytes yog dab tsi?
Chrysophytes yog ib pab pawg tseem ceeb ntawm lub nceeg vaj Protista. Nws suav nrog diatoms thiab desmids. Desmids tseem hu ua golden algae. Chrysophytes tau muab faib ua kwv yees li ib puas genera nrog ntau tshaj 1000 hom chrysophytes piav. Lawv feem ntau yog cov kab mob photosynthetic pom nyob rau hauv dej tshiab thiab dej hiav txwv.
Daim duab 01: Diatoms
Diatoms yog cov neeg tsim khoom loj hauv cov dej hauv dej. Lawv muaj qhov tshwj xeeb ob lub plhaub ua los ntawm silica. Li no, lawv tshwm li cov thawv me me nrog lub hau. Qee qhov piv txwv ntawm diatoms yog Cymbella, Navicula thiab Melosira. Lawv yog cov kab mob unicellular eukaryotic. Lawv yog cov microscopic thiab ntab passively hauv cov dej ntws. Chrysophytes tsim ib qho tshwj xeeb carbohydrate hu ua chrysolaminin. Lawv muaj cov phab ntsa ntawm tes ua los ntawm cellulose ntxiv dag zog los ntawm silica compounds. Tab sis, amoeboid cov ntaub ntawv chrysophytes tsis muaj phab ntsa ntawm tes.
Euglenoids yog dab tsi?
Euglenoids yog ib leeg-cell flagellated kab mob ntawm lub nceeg vaj Protista. Lawv yog ib pawg loj ntawm algae. Muaj txog 54 genera thiab 900 hom nyob rau hauv pawg no. Lawv nyob hauv dej tshiab, dej khov thiab kuj nyob hauv dej hiav txwv. Tab sis lawv feem ntau pom nyob rau hauv dej tshiab, uas yog nplua nuj nyob rau hauv cov ntaub ntawv organic. Euglena thiab Phacus yog ob tus neeg sawv cev ntawm euglenoids. Feem ntau euglenoids yog unicellular tshwj tsis yog cov colonial genus Colacium. Ntau euglenoids yog spindle-puab. Ntau ntawm lawv muaj chloroplasts, yog li lawv yog photosynthetic. Lwm tus pub los ntawm phagocytosis los yog diffusion.
Daim duab 02: Euglenoid
Tsis tas li ntawd, lawv muaj ob lub chij; ib qho yog ntev thiab ua haujlwm thaum lwm tus yog luv thiab tsis protrude. Euglenoids tsis muaj phab ntsa ntawm tes. Lawv muaj protein ntau ntawm tes npog hu ua pellicle, uas muab kev yooj yim rau euglenoids. Ntxiv mus, euglenoids muaj qhov muag pom kev uas ua raws li lub teeb pom kev. Lawv kuj muaj ib tug contractile vacuole. Nws pab euglenoids kom nqus dej ntau dhau ntawm lawv lub cev. Tsis tas li ntawd, qee qhov euglenoids muaj peev xwm tsim cov spores so uas muaj txiaj ntsig zoo nyob rau hauv ib puag ncig tsis zoo.
Dab tsi yog qhov zoo sib xws ntawm Chrysophytes thiab Euglenoids?
- Chrysophytes thiab euglenoids yog ob ntawm tsib pawg ntawm lub nceeg vaj Protista.
- Lawv yog cov kab mob unicellular eukaryotic.
- Ob leeg yog cov kab mob hauv dej.
- Lawv feem ntau yog photosynthetic; li no lawv thiaj li zoo li cov nroj tsuag zoo li protists.
- Lawv yog flagellates.
- Ob leeg yog algae.
Qhov txawv ntawm Chrysophytes thiab Euglenoids yog dab tsi?
Chrysophytes yog cov nroj tsuag zoo li cov neeg tiv thaiv pom nyob rau hauv marine thiab dej tshiab ib puag ncig, thaum euglenoids yog ib pawg ntawm Protista uas suav nrog ib leeg-celled algae nrog pellicle thiab qhov muag. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chrysophytes thiab euglenoids. Ntxiv mus, chrysophytes muaj cov phab ntsa ntawm tes ua los ntawm cellulose, ntxiv dag zog los ntawm silica tebchaw, thaum euglenoids tsis muaj cellulosic phab ntsa. Tsis tas li ntawd, chrysophytes muaj cov xim xws li chlorophylls a thiab c, fucoxanthin thiab xanthophylls, thaum euglenoids muaj chlorophylls a thiab b, thiab carotenoids.
Cov hauv qab no infographic teev qhov sib txawv tseem ceeb ntawm chrysophytes thiab euglenoids hauv daim ntawv.
Summary – Chrysophytes vs Euglenoids
Chrysophytes thiab euglenoids yog ob pawg ntawm Protista. Lawv yog cov unicellular, dej thiab feem ntau photosynthetic eukaryotic kab mob. Chrysophytes yog cov nroj tsuag zoo li, thaum euglenoids qhia ob qho tib si cov nroj tsuag zoo li thiab tsiaj zoo li cov yam ntxwv. Chrysophytes yog ob hom diatoms thiab desmids. Chrysophytes muaj cov phab ntsa ntawm tes, thaum euglenoids tsis muaj cov phab ntsa ntawm tes tsim los ntawm cellulose. Euglenoids muaj qhov muag pom thiab pellicle, tsis zoo li chrysophytes. Yog li, qhov no qhia txog qhov sib txawv ntawm chrysophytes thiab euglenoids.
