Qhov sib txawv tseem ceeb ntawm actinomorphic thiab zygomorphic paj yog cov paj actinomorphic yog ib lub paj uas yog radially symmetrical thiab tuaj yeem muab faib ua ob qhov sib npaug ntawm txhua txoj kab uas hla thaum zygomorphic paj yog paj uas yog ob sab symmetrical thiab tuaj yeem muab faib ua ob qho tib si. ob qhov sib npaug nkaus xwb hauv ib lub dav hlau.
Floral symmetry piav qhia seb lub paj puas tuaj yeem muab faib ua daim iav duab. Qee cov paj yog radially symmetrical thaum qee cov paj yog ob sab sib luag. Txawm li cas los xij, qee cov paj yog asymmetrical. Paj nrog radial symmetry tuaj yeem muab faib ua ib nrab ib nrab ntawm txhua txoj kab uas hla. Cov paj no hu ua actinomorphic paj. Hauv qhov sib piv, paj nrog ob sab symmetry tuaj yeem muab faib ua ob qhov sib npaug hauv ib lub dav hlau. Cov paj no hu ua zygomorphic paj.
Actinomorphic Paj yog dab tsi?
Ib lub paj actinomorphic yog paj uas tuaj yeem muab faib ua peb lossis ntau qhov sib npaug ntawm txhua txoj kab uas hla lossis ib lub dav hlau ntsug. Feem ntau cov paj yog actinomorphic. Lawv yog radially symmetrical thiab lub hnub qub-puab paj li niaj zaus. Floral kab mob ntawm actinomorphic paj yog sib npaug ntawm qhov loj. Yog li ntawd, lawv yog cov paj tsis tu ncua.
Daim duab 01: Actinomorphic Paj
Thaum bisected nyob rau hauv ib txoj kab uas hla, actinomorphic paj muab ob halves zoo tib yam. Romulea rosea paj yog cov paj actinomorphic. Tsis tas li ntawd, lily (Lilium, Liliaceae) thiab buttercup (Ranunculus, Ranunculaceae) paj kuj yog paj actinomorphic. Cov paj Actinomorphic yog cov cim basal ntawm angiosperms.
Zygomorphic Paj yog dab tsi?
A zygomorphic paj yog paj uas tuaj yeem muab faib ua ob daim iav los ntawm ib lub dav hlau nkaus xwb. Zoo sib xws halves tuaj yeem tau los ntawm tsuas yog ib lub dav hlau ntsug. Cov paj no yog ob sab symmetrical. Zygomorphic paj muaj cov paj uas tsis sib xws. Corolla tshwj xeeb tshaj yog muaj qhov sib npaug ntawm cov nplooj, yog li lawv yog cov paj tsis sib xws.
Daim duab 02: Zygomorphic Paj
Gladiolus paj (Iridaceae) yog ib qho piv txwv ntawm paj zygomorphic. Ntxiv mus, orchids thiab paj ntawm feem ntau cov tswv cuab ntawm Lamiales yog zygomorphic paj. Zygomorphic paj yog tus cwj pwm los ntawm angiosperms. Muaj peb hom zygomorphic paj raws li feem ntau zygomorphic, transversely zygomorphic thiab obliquely zygomorphic.
Dab tsi yog qhov zoo sib xws ntawm Actinomorphic thiab Zygomorphic Paj?
- Actinomorphic thiab zygomorphic paj yog ob hom paj raws li lawv qhov sib luag.
- Ob hom paj muab daim iav duab thaum bisected.
Qhov txawv ntawm Actinomorphic thiab Zygomorphic Paj yog dab tsi?
Actinomorphic paj muab ob qho tib si zoo sib xws thaum muab faib ua ib txoj kab uas hla. Hauv qhov sib piv, zygomorphic paj tsim ob daim iav dluab thaum bisected hauv ib lub dav hlau xwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm actinomorphic thiab zygomorphic paj. Cov paj Actinomorphic muaj qhov sib npaug ntawm cov paj paj thaum lub paj zygomorphic muaj qhov sib npaug ntawm cov paj hauv nruab nrog cev. Ntxiv mus, actinomorphic paj yog cov paj tsis tu ncua thaum zygomorphic paj yog paj tsis xwm yeem. Roses, lilies, thiab buttercups yog cov piv txwv ntawm cov paj actinomorphic thaum orchids yog ib qho piv txwv ntawm zygomorphic paj.
Cov lus hauv qab no qhia txog qhov txawv ntawm actinomorphic thiab zygomorphic paj.
Summary – Actinomorphic vs Zygomorphic Paj
Actinomorphic paj yog ib lub paj radially symmetrical. Nws tsim cov duab iav thaum bisected raws txhua lub dav hlau ntsug. Nyob rau hauv sib piv, zygomorphic paj yog ib tug bilaterally symmetrical paj. Nws tsim ob daim iav duab tsuas yog los ntawm ib lub dav hlau ntsug. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm actinomorphic thiab zygomorphic paj. Zygomorphic paj muaj qhov sib npaug ntawm cov paj thaum lub paj actinomorphic muaj qhov sib npaug ntawm cov paj, tshwj xeeb tshaj yog cov paj. Yog li ntawd, cov paj actinomorphic yog cov paj tsis tu ncua, thaum paj zygomorphic yog paj tsis xwm yeem.
