Diatoms yog unicellular, colonial, lossis filamentous autotrophic cov kab mob uas nyob hauv cov chaw nyob hauv dej hiav txwv thiab dej tshiab. Diatoms yog heterokonts, tab sis feem ntau tsis muaj flagella, tshwj tsis yog ntawm gametes.
Puas yog feem ntau diatoms Heterotrophs lossis Autotrophs?
Txawm hais tias feem ntau cov diatoms yog autotrophic, qee hom heterotrophic lossis symbiotic tuaj yeem pom hauv cov chaw tshwj xeeb. Cov teeb meem nyob ntawm txhua diatom yog nyob rau hauv ib lub plhaub ntawm silica uas nws secretes. Cov plhaub no yog cim los ntawm feeb pores lossis kev nyuaj siab uas tso cai rau cov kab mob muaj sia nkag mus rau nws ib puag ncig.
Puas yog diatoms photosynthetic lossis heterotrophic?
Lub zog qhov chaw. Diatoms yog feem ntau yog photosynthetic; Txawm li cas los xij, ob peb lub luag haujlwm heterotrophs thiab tuaj yeem nyob hauv qhov tsis muaj lub teeb muab qhov tsim nyog cov pa roj carbon zoo muaj.
Dab tsi yog autotrophic diatoms?
Autotrophic cov kab mob unicellular yog thawj qhov khoom noj rau zooplankton. Cov kab mob autotrophic uas hu ua diatoms yog plankton uas tsis muaj flagella (tshwj tsis yog txiv neej gametes). Frustules (plhaub lossis li qub) yog sib tshooj zoo li lub thawv "pill" thiab ua los ntawm opaline silica.
Puas yog xim av algae yog Autotroph?
Cov algae yog autotrophic protists uas tuaj yeem ua unicellular lossis multicellular. Cov kab mob no muaj nyob hauv cov pab pawg loj Chromalveolata (dinoflagellates, diatoms, golden algae, thiab xim av.algae) thiab Archaeplastida (liab algae thiab ntsuab algae).
