Yintoni i-perianth yeentyatyambo?

Iintyatyambo zizakhiwo ezintsonkothileyo. Zibonakala zilula kakhulu kuthi, kodwa ukuba sima okomzuzwana ukujonga icandelo ngalinye, siyakuqonda ukuba inyani, kwakhona, idlula intsomi.

Elinye lala macandelo ahlala eneentyatyambo ezininzi yi perianth, kwaye yeyona inomdla ebantwini, kuba yeyona isincedayo ukugqiba ngesityalo okanye esinye.

Yintoni i-perianth?

Ixesha imvulophu engqongeyo kwaye ikhusele amalungu esini sentyatyambo. Kuyinyumba, kodwa oko akuthethi ukuba ayizalisekisi indima ebalulekileyo ekuvelisweni kwesityalo. Ngapha koko, uninzi lwengcoliseko lukhokelwa yimibala kunye / okanye iimilo zeperianth zokuthwala umungu usiya kwihlazo, ukusuka apho uyakudlula uye kwi-ovary kwaye ukusuka apho uye kwi-ovule.

Yenziwe ngamaqhekeza amabini:

ICorolla

I-corolla yenziwa ngamagqabi, kodwa kufanele kuqatshelwe ukuba xa ii-sepals kunye neepalali zinombala ofanayo, zibizwa ngokuba ziitape. Kuluxanduva lokutsala izinambuzane eziya kuthi zingcolise intyatyambo.

Iindidi zeCorolla

Ngokwe-symmetry yayo:

• Umtsalane: yiyo enokwahlulwahlulwahlulwahlulwahlulwahlamacandelo afanayo.
• Zygomorphic: yile ithi, ukuba inqunyulwe phakathi, kufumaneke iihafu ezibini ezahlukeneyo.

Inqaku elidibeneyo:

Yintoni i-actinomorphic kunye ne-zygomorphic flower?

Ngokutsho komanyano weepalali:

• Dialipetal: kolu hlobo iipetali azimanyananga.
  • Imizekelo: Rosa (roses), UDianthus (Ukutya), uPapaver (iipoppies).
• IGamopétalakule meko, iipalali zimanyene ngokupheleleyo okanye ngokuyinxenye.
  • Imizekelo: ICampanula, Lamium, Erica (heather), Vaccinium (iblueberry).

I-Chalice

Ikomityi Yeyona ndawo ingaphandle yeperianth, kwaye yenziwe ngamangcwaba Umsebenzi wawo kukukhusela ubume beentyatyambo. Ihlala iluhlaza ngombala, kwaye inembonakalo yamagqabi eguqulweyo.

I-Sepals banokuba neentlobo ngeentlobo zeemilo kunye nexesha lokuphilaKuxhomekeke kuhlobo lwesityalo. Umzekelo, kwiintyatyambo ezimbaxa, ziye zinciphiswe zibe ziinwele ekuthiwa yipapus okanye i-vilano.

Ngapha koko, kwimeko yemithi yeziqhamo emininzi, enje Malus yekhaya (umthi weapile), ezi zigcinwa kwisityalo kude kube iziqhamo zivuthwe ngokupheleleyo. Ngokuchasene noko, kwi-Papaver (poppies), ziwa ngokukhawuleza xa intyatyambo ivula.

Zingaphi iindidi zeperianth ezikhoyo?

Zintathu iintlobo:

• Monoclamid perianth: xa ingenazo iipalali okanye ii-sepals.
• Homoclamid perianth: ukuba inezilwanyana ezifanayo kunye neepals, kwimeko apho intyatyambo kuthiwa ineetape.
• IHeteroclamide perianth: kuxa iipatali kunye neepal zihlukile.

Kwaye kukho nolunye uhlobo lwentyatyambo, ekuthiwa yi-aclamide flower. Lo ngulo ungenayo i-perianth.

Ngaba ubusazi iimpawu zeli perianth?
