Chii chinonzi actinomorphic uye zygomorphic ruva?

Maruva anogona kuverengerwa munzira dzakawanda: zvinoenderana neruvara, saizi, rudzi rwebhotani rwunogadzirwa nemuti wacho,… uyezve nezvekuti maruva awo anogovaniswa sei. Mupfungwa iyi, vanogona kuva zygomorphic kana actinomorphic.

Kana iwe uchida kuziva kuti hunhu hwerudzi rupi zvarwo uye mimwe mienzaniso yemiti inozvigadzira, ipapo iwe unozokwanisa kuziva 🙂.

Ndeapi maitiro eactinomorphic uye zygomorphic maruva?

Actinomorphic

Iyo actinomorphic ruva ndeye iyo ine radial symmetry; ndiko kuti, anogona kukamurwa muzvikamu zvitatu kana zvimwe zvakafanana zvine hukama. Zvakare, zvinogona kana kusapatsanurwa kuita mahafu maviri akaenzana.

Kuita kuti zvive nyore kunzwisisa, iwe unozoziva kana iri actinomorphic kana, kana iwe uchicheka iyo hafu, iwe une maviri chaiwo iwo mahafu akaenzana. Izvi hazvizove zvakadaro kana iri zygomorphic, sezvo chimwe chezvikamu chichagara chakakura kudarika chimwe.

Mienzaniso

Sezvatakataura, ruzhinji rwezvirimwa zvine mhando iyi yemaruva, asi pane zvisaririra: mazhinji emhuri diki dzemhuri yeFabaceae, kunze kweMimosoideae naCaesalpinioideae, mamwe scrofulariaceae uye orchids ane zygomorphs. Heano mamwe eai actinomorphic maruva emichero:

BougainvilleaBougainvillea spectabilis)

Icho chinogara chiri chegirini kana chakashata shrub zvinoenderana nemamiriro ekutanga eBrazil. Iyo yakanaka kwazvo uye isinganetsi kutarisira chirimwa icho chazove chakakurumbira munzvimbo dzinopisa dzemamiriro ekunze epasi.

Nyaya inoenderana:

Bougainvillea spectabilis

Geranium yemigwagwa (geranium molle)

Icho chirimwa chegore rega chine pubescent madzinde nemashizha, yakazvarirwa kuEurope kunze kweIceland. Inogona kuwanikwa zviri nyore munzvimbo dzakasviba, matunduru, uye mukucheka mafuro.

Flamboyan (royal delonix)

Iyo yakasarudzika, semi-evergreen kana evergreen muti zvinoenderana nemamiriro ekunze ekuMadagascar. Iyo ine yakanyanya yakashongedzwa kukosha, ndosaka ichirimwa munzvimbo dzinopisa uye dzinopisa dzenyika kutenderera pasirese.

Nyaya inoenderana:

Flamboyant

Tea chirimwa (Camellia sinensis)

Iyo igreen shrub kana muti Pakutanga kubva kumaodzanyemba kweChina, inozivikanwa kwazvo pamashizha ayo, nekuti tii inogadzirwa navo. Zvisinei, maruva ayo anokoshawo: anoyera masendimita mana, uye akanaka kwazvo akachena-akachena.

Nyaya inoenderana:

Camellia sinensis

Zygomorphic

Zygomorphic ruva ndeimwe ine ndege yekudyidzana kwenyika mbiri, kana chii chakafanana: kana uchimupatsanura nepakati, panogara paine mahafu maviri akasiyana, kungave muhukuru, muhuwandu hwemapeturu uye / kana sepals kana bracts, ... kana mune ese kamwechete.

Mienzaniso

Mimwe mienzaniso zvirimwa mumhuri yeFaboideae, senge inotevera:

Vetch (pisum sativum)

Iyo yegore kutenderera miriwo ine yakawanda kana shoma tsika yekukwira. chizvarwa kuMediterranean bheseni. Inokurudzirwa zvakanyanya kune mhodzi dzayo, inonziwo mapea kana mapizi, ayo anogadzirirwa dzakasiyana ndiro.

Nyaya inoenderana:

Kurimwa kwepea

Alfalfa (medicago sativa)

Iyo isingaperi yemiriwo ine yakamira uye inobuditsa madzinde anowanikwa kuPersia yakadyarwa zvakanyanya uye inoshandiswa pasirese souswa.

Nyaya inoenderana:

Alfalfa kurima

Bhinzi (Phaseolus vulgaris)

Ndiwo mushonga wegore rino unomera wakamira kana seanokwira akaberekerwa kuMesoamerica. Inobereka michero ine mbeu dzinenge gumi imwe neimwe, inonzi bhinzi, itsvo bhinzi kana bhinzi. Izvi zvinodyiwa.

Nyaya inoenderana:

Bhinzi (Phaseolus vulgaris)

Hupfu bhinzi (vicia bhinzi)

Ndicho yegore kutenderera uswa yemuno mudunhu reMediterranean kana Central Asia (haisati yajeka), iine yakatwasuka yakatakura. Inorimirwa mhodzi dzayo, dzakakodzera kudyiwa nevanhu.

Nyaya inoenderana:

Hupfu bhinzi: gadzira gwara

Ndeapi maruva uye ndeapi?

Maruva akakosha kwazvo zvikamu zveaiiosperms. Kutenda kwavari, inogona kugadzira zvizvarwa zvitsva, uye nekudaro, chengetedza mhando iri mupenyu kwenguva yakareba kwazvo (zviuru, pamwe mamirioni emakore).

Nekudaro, kunyangwe hazvo nhasi kuti vanogona kukonzeresa kurwisa kwevamwe vanhu (kusanganisira ini) mhino hadzisi nangananga yavo, asi stigmata yemamwe maruva.

Zvinotendwa kuti zvakaonekwa makore zviuru zana nemakumi mana apfuura, pakutanga kweCretaceous period, munzvimbo dzakaderera. Zvisinei, pakanga pasina kusvika makore anosvika mamirioni 65-75 akapfuura kuti ivo vakakwanisa kukunda biomes ese epasi Pasi kunze kwenzvimbo dze polar.

Mazhinji acho ane mavara akajekaUye izvi ndezve chikonzero: mune zvakasikwa kune akati wandei mhuka dzinovhotesa mapollinator uye mazhinji, akawanda zvirimwa. Neichi chikonzero, maruva anofanirwa kuita zvese zvinobvira kukwezva angangoita mamwe acho, nekuti makwikwi pane dzimwe nzvimbo anogona kunge ari akakwirira kwazvo.

Asi kune dzimwewo dzinoenda dzisingazivikanwe, senge izvo zve aspidistra Semuyenzaniso. Dzake idiki zvekuti, kana dzikamera pakati pemadzinde, hadziwanzo kuoneka. Nei izvi zvichiitika?

Zvakanaka, kana iwe ukamboona kana kuwana chirimwa icho chinenge chisina kumbotumbuka, iwe unofanira kutanga kuzvibvunza iwe kana chiri angioperm kana kana zviri zvinopesana gymnosperm: kana chiri chekutanga, ipapo unogona kuva nechokwadi chekuti pane imwe nguva mukushanduka kwayo 'yakapa' basa rechipembenene kana mhuka iyo isingakwanise kusiyanisa mavara, isina hwema, uye / kana husiku . Ipapo iwe unogona kutsvaga maruva -kana zvisaririra zvemaruva buds- zvidiki, mavara anoenda asingaonekwe - senge girini- uye / kana isina hwema.

Iwe wafungei nezvenyaya iyi?
