Yam ntxwv ntawm Protists
Protists yog cov kab mob eukaryotic uas tsis tuaj yeem faib ua cov nroj tsuag, tsiaj txhu, lossis fungus. Lawv feem ntau yog unicellular, tab sis qee qhov, zoo li algae, yog multicellular. Kelp, los yog 'seaweed,' yog ib tug loj multicellular protist uas muab zaub mov, vaj tse, thiab oxygen rau ntau lub hauv qab dej
Ntawm no, dab tsi yog cov yam ntxwv tseem ceeb ntawm protists?
Protists yog eukaryotes, uas txhais tau hais tias lawv cov cell muaj ib tug nucleus thiab lwm yam membrane-bound organelles. Feem ntau, tab sis notall, protists yog ib leeg xwb. Lwm yam tshaj li cov no nta , lawv muaj tsawg heev sib xws. Koj tuaj yeem xav txog protists Raws li tag nrho cov kab mob eukaryotic uas tsis yog tsiaj txhu, lossis nroj tsuag, lossis cov kab mob fungi.
Ib yam li ntawd, qhov tseem ceeb ntawm protists yog dab tsi? Cov slime pwm yog tseem ceeb rau ecosystems vim lawv yog decomposers, uas tso tawm cov as-ham tseem ceeb rov qab mus rau ib puag ncig. Koj tuaj yeem hais tias lub neej hauv ntiaj teb nyob ntawm qhov protists vim tias lawv muab peb cov pa oxygen, yog cov kab mob tseem ceeb hauv cov khoom noj khoom haus, thiab rov ua dua tshiab tseem ceeb cov as-ham rau lwm yam kev ua neej siv.
Kuj kom paub yog, dab tsi yog yam ntxwv ntawm monera?
Cov yam ntxwv ntawm Monera
- Monerans yog unicellular kab mob.
- Lawv muaj 70S ribosomes.
- DNA yog liab qab thiab tsis yog khi los ntawm ib daim nyias nyias.
- Nws tsis muaj organelles xws li mitochondria, lysosomes, plastids, Golgi lub cev, endoplasmic reticulum, centrosome, thiab lwm yam.
- Lawv reproduce asexually los ntawm binary fission los yog budding.
Koj faib cov protists li cas?
Cov protists tuaj yeem yog cais rau hauv ib qho ntawm peb pawg tseem ceeb, tsiaj-zoo li, nroj tsuag-zoo li, thiab fungus-zoo li. Grouping rau hauv ib qho ntawm peb pawg yog raws li lub cev'smode ntawm kev yug me nyuam, txoj kev ntawm kev noj haus, thiab motility.

Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
