Choanocytes yog lub cev hlwb ntawm daim txhuam cev thiab cov pinacocytes yog cov hlwb zoo li qub uas ua rau lub pinacoderm ntawm daim txhuam cev. Qhov sib txawv tseem ceeb ntawm choanocytes thiab pinacocytes yog tias choanocytes muaj flagella thaum pinacocytes tsis muaj flagella.
Spongiology yog ceg ntawm biology uas tsom mus rau kev kawm ntawm daim txhuam cev. Sponges belongs rau phylum Porifera. Lawv yog cov kab mob ntau hom kab mob uas muaj qhov pores hauv lub cev uas pab txhawb dej ntws.
Choanocytes yog dab tsi?
Cov no yog cov hlwb uas ua rau sab hauv ntawm daim txhuam cev uas suav nrog tag nrho peb lub cev hom: asconoid, syconoid, thiab leuconoid. Lawv txhua tus muaj flagella. Choanocytes zoo ib yam li choanoflagellates thiab tsim cov dej ntws thaum lub sijhawm txav mus los. Thiab yog li, pab cov sponges kom khaws cov pa oxygen thiab cov as-ham. Tsis tas li ntawd, nws txhim kho txoj kev ua pa thiab digestive. Nws lwm txoj haujlwm suav nrog kev nqa cov khoom noj thiab xa tawm cov khoom zom rau amoebocytes.
Daim duab 01: Choanocytes
Txawm tias cov sponges tsis muaj cov kab mob hauv lub cev, cov choanocytes muaj lub peev xwm tshwj xeeb los hloov mus rau spermatocytes thaum xav tau kev sib deev. Cov spongocoel ntawm asconoid sponges thiab radial canals ntawm syconoid sponges muaj cov hlwb. Tsis tas li ntawd, nyob rau hauv leuconoid daim txhuam cev, cov hlwb no muaj nyob rau hauv chambers.
Pinacoytes yog dab tsi?
Pinacocytes yog cov hlwb tiaj tus nyob hauv cov txheej txheem ntawm tes feem ntau ntawm daim txhuam cev. Lawv tsis muaj flagellum. Pinacoderm yog lub npe nrov rau txheej txheej sab nraud ntawm cov cell. Tsis tas li ntawd, muaj peb yam tseem ceeb ntawm cov cell tiaj tus. Lawv yog, basipinacocytes (nyob rau hauv kev sib cuag nrog rau saum npoo uas daim txhuam cev txuas), exopinacocytes (hlwb ntawm daim txhuam cev), endopinacocytes (cov cell uas kab cov kwj dej ntawm daim txhuam cev).
Daim duab 02: Daim txhuam cev
Ntxiv mus, cov hlwb no muaj ntau cov granules uas muaj peev xwm ntawm kev cog lus. Ntxiv mus, cov cell tiaj tus tuav qhov loj thiab cov qauv ntawm daim txhuam cev los ntawm kev cog lus thiab so.
Dab tsi yog qhov zoo sib xws ntawm Choanocytes thiab Pinacocytes?
- Choanocytes thiab Pinacocytes yog cov hlwb uas koom nrog phylum Porifera.
- Ob lub hlwb muaj nyob hauv lub cev ntawm daim txhuam cev.
Qhov txawv ntawm Choanocytes thiab Pinacocytes yog dab tsi?

Summary – Choanocytes vs. Pinacocytes
Sponges belongs rau phylum Porifera. Choanocytes yog cov hlwb nrog lub flagellum thaum pinacocytes tsim cov pinacoderm ntawm daim txhuam cev. Ob leeg muab qhov tseem ceeb ntawm tes zoo rau daim txhuam cev. Choanocytes pab khaws cov pa oxygen thiab cov as-ham thaum pinacocytes muab cov duab zoo rau lub cev los ntawm kev cog lus thiab so. Qhov no yog qhov sib txawv tseem ceeb ntawm choanocytes thiab pinacocytes.
