Qhov sib txawv tseem ceeb ntawm setae thiab chaetae yog tias setae yog cov qauv zoo li bristle tam sim no nyob rau hauv ob qho tib si vertebrates thiab invertebrates, thaum chaetae yog chitinous bristle zoo li cov qauv tam sim no nyob rau hauv feem ntau hom fungal.
Setae thiab chaetae yog ob qho tib si zoo li cov qauv uas feem ntau pab txhawb kev txav chaw thiab txuas ntawm cov kab mob. Nws yog ib qho tseem ceeb hauv cov kab mob uas muaj sia nyob rau nws txoj sia nyob. Yog li ntawd, los ntawm evolution, nyob ntawm seb hom ntawm ib puag ncig, cov kab mob muaj feem xyuam nrog ntau hom qauv. Yog li, setae thiab chaetae yog cov qauv uas tau pab nyob rau hauv kev ciaj sia ntawm cov kab mob thaum lub sij hawm evolution.
Setae yog dab tsi?
Setae yog cov plaub hau zoo li cov plaub hau uas pom nyob rau hauv ob qho tib si vertebrates thiab invertebrates. Nws lub ntsiab lus zoo yog seta. Nyob rau hauv invertebrates, nws yog tsuas yog tam sim no nyob rau hauv annelids thiab crustaceans. Nyob rau hauv annelids, setae yog txhav nyob rau hauv cov xwm. Lawv pab cov annelids txuas mus rau saum npoo thiab tiv thaiv backsliding thaum lawv txav. Tsis tas li ntawd, nyob rau hauv ib co kab mob, lub setae ua raws li lub podia thiab pab kom txav mus los. Hauv crustaceans, setae feem ntau yog kab ntawm qhov ncauj kab noj hniav thiab qee zaum sib txawv rau hauv cov nplai, uas ua rau lawv ntes tau thov Vajtswv. Hauv qee cov kab, setae raug tshuaj lom los yog muaj peev xwm ua raws li kev tiv thaiv mechanism.
Daim duab 01: Setae
Cov setae tshwm sim los ntawm trichogen. Nws tseem hu ua bristle generator. Lawv tshwm sim raws li cov qauv hollow. Thaum maturation, lawv tau mus rau ib tug hardening txheej txheem thiab project los ntawm lub thib ob accessory hlwb. Tom qab ntawd lawv tsim ib daim nyias nyias thiab tsim mus rau hauv setae, macrotrichia, chaetae lossis nplai.
Qee cov vertebrates kuj muaj setae los yog cov qauv zoo sib xws. Qee hom kab mob fungal thiab nroj tsuag kuj muaj cov qauv zoo sib xws; Txawm li cas los xij, feem ntau yog microscopic hauv qhov xwm txheej.
Chaetae yog dab tsi?
Chaetae yog ib hom setae uas muaj chitin hauv lawv cov plaub hau zoo li cov plaub hau. Yog li, cov no tseem hu ua chitinous bristles lossis chitinous setae. Lawv feem ntau pom muaj nyob rau hauv fungi; Txawm li cas los xij, qee qhov annelids kuj muaj chaetae. Lawv lub luag haujlwm tseem ceeb zoo ib yam li ntawm setae. Lawv kuj koom nrog hauv kev sib txuas ntawm lub cev mus rau saum npoo, kev yooj yim ntawm kev txav thiab qee zaum pab raws li kev tiv thaiv hom.
Daim duab 02: Chaetae
Nyob rau hauv cov kab mob, cov chaetae feem ntau yog microscopic. Txawm li cas los xij, hauv qee hom, lawv tuaj yeem pom hauv qab tes lens. Zoo ib yam li setae, chaetae kuj tshwm sim los ntawm trichogen. Thaum maturation, chitin deposits rau ntawm bristles kom harden cov qauv.
Dab tsi yog qhov zoo sib xws ntawm Setae thiab Chaetae?
- Cov no yog cov qauv zoo li bristle lossis cov plaub hau zoo li cov qauv.
- Ntxiv mus, ob qho tib si tshwm sim los ntawm trichogen thiab paub tab rau hauv cov qauv tawv.
- Lawv tsim cov hlab ntsha uas tom qab tsim los ua tawv tawv.
- Kuj, ob qho tib si tseem ceeb hauv kev sib txuas, txav thiab ua cov txheej txheem tiv thaiv.
- Ob leeg tuaj yeem pom hauv daim ntawv sau npe.
- Lawv feem ntau yog microscopic hauv xwm; Txawm li cas los xij, hauv qee yam kab mob, nws tuaj yeem pom tau siv lub lens tes.
Qhov txawv ntawm Setae thiab Chaetae yog dab tsi?
Ob leeg setae thiab chaetae zoo sib xws hauv cov qauv thiab ua haujlwm rau ib leeg. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm setae thiab chaetae yog nyob rau hauv cov khoom ntawm ob lub qauv. Thaum setae muaj cov polysaccharides thiab lipids ua lawv cov khoom tawv, chaetae feem ntau yog chitin.
Cov hauv qab no qhia txog qhov sib txawv ntawm setae thiab chaetae.
Summary – Setae vs Chaetae
Setae thiab chaetae yog ob lub qauv muaj nyob rau hauv feem ntau annelids thiab crustaceans. Lub luag haujlwm tseem ceeb ntawm ob qho tib si yog ua raws li cov qauv zoo li bristle uas pab txhawb kev txuas thiab locomotion. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm setae thiab chaetae yog tias chaetae muaj chitin nyob rau hauv cov plaub hau zoo li bristles, as opposed to setae. Chitin deposition tshwm sim thaum lub sij hawm hardening txheej txheem ntawm chaetae. Ob leeg muaj cov qauv zoo sib xws thiab tshwm sim los ntawm trichogen thiab tom qab ntawd loj hlob mus rau hauv cov plaub hau tuab zoo li bristles. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm setae thiab chaetae.
