Yintoni isitovu sesityalo?

Ixesha isitokhwe Kwi-botany ineentsingiselo ezininzi, oko kuthetha ukuba isetyenziselwa ukubhekisa kwinxalenye ethile yeentlobo ezahlukeneyo zezityalo. Eli candelo linokuba yitrunk okanye i-pseudo-trunk kwezinye iimeko, i-inflorescence kwezinye, ... isetyenziselwa ukubiza ubume be-algae enkulu.

Ngenxa yoko, ukusebenza kwayo kuyahluka, nangona singasishwankathela ngegama elinye: gcina, okanye ukuba ukhetha, manyani. Uyadida? Siza kuyichaza ngokweenkcukacha.

Ingaba ithetha ntoni isitokhwe kwizityalo?

Igama elithi stipe lineentsingiselo ezininzi, ukuze kube lula ukufunda siye sahlula-hlula inqaku ngokwamacandelo ahlukeneyo, njengoko kukho intsingiselo yekota:

I-pseudo-trunk (trunk false)

Kukho izityalo ezithile ezingavelisi buti bokwenene, njengemithi yesundu kunye iifeni zomthi. Oku yenziwe kwiintsalela zepetiyoli (iziqu ezidibanisa igqabi kunye nesiqu, isitampu okanye isebe) lamagqabi abesifa okoko imbewu, okanye isiporho ukuba yintsimbi.

Ngokungafaniyo nesiqu sokwenyani, nje ukuba ifikelele kububanzi bayo iyayeka ukutyeba. Ngapha koko, xa oko kungenakwenzeka, nokuba kungenxa yokuba kuhlume kwi-asphalt, okanye kwindawo egcwele amatye kunye / okanye icwecwe kakhulu, iya kumisa ukukhula kwayo kwakamsinya nje ukuba kuphume isithuba. Ukongeza, ayisebenzi isebe, ngaphandle kokuba ifumene umonakalo omkhulu (umzekelo, ibethwe ngumbane) kwisikhokelo sayo sokukhula.

Kwelinye icala, ngelixa ukwazi iminyaka yobudala bomthi ngokubala amakhonkco okukhula, enziwa minyaka le, kwimeko yemithi yesundu kunye neeferns unokwazi kuphela ubudala babo ukuba uyazi ukuba zazivela nini, okanye ukuba thelekisa nezinye iindidi zohlobo lwazo.

Isitayile seentyatyambo

Zininzi izityalo ezingazivelisi iintyatyambo ezizodwa, kodwa uninzi luhluma kwisikhondo esinye. Kule meko ithile, isitampu sisiqu esifutshane okanye esingaphantsi esifutshane esijoyina inxalenye yeli inflorescence isityalo. Ke, kuxhomekeke ekusebenzeni kwayo, ifumana igama okanye elinye, eyona ixhaphakileyo yile ilandelayo:

• Ukujikeleza okanye ukubuzasisiqu esine-inflorescence ye-non-capitular exhasa intyatyambo kwaye iyidibanise nesityalo sonke. Ikwajongene nokondla le ntyatyambo, kuba incindi ihanjiswa ngaphakathi.
• Ndiyasinda: sisiqu esingenamagqabi, kodwa sineentyatyambo eziphuma esiphelweni saso. Ikho kwii poppies, iisundews, bromeliads, amaryllis, kunye iimfusa, phakathi kwabanye.

Ukucoca gynoecium

Ukuqhubeka kunye ne-inflorescence, isitampu inokuba yinto eyaziwa ngokuba yi-gynoecium stipitate, okanye i-gynopod njengoko ibizwa njalo. Oku kufumaneka kwizityalo eziphezulu, ezinje nge Iinkqubo. Kule meko, lulwandiso lwe-ovary kwaye ujoyine i-thalamus, esisakhiwo apho kufakwa khona iinxalenye ezahlukeneyo zentyatyambo.

IRostelo (iiorchid)

Ii-Orchids zineentyatyambo ezinobunkunkqele, kodwa zikhona, ezifana nezohlobo lweCochlioda, ezinzima ngakumbi ukuba kunokwenzeka. Ubume bayo beentyatyambo bunestepe, esivela kwirostellum. I-rostellum luhlobo lwekholamu engenazintsholongwane ekhusela i-polinarium, oko kukuthi, apho umungu wenziwa khona.

Ulwelwe

Sithethile ngezityalo, kodwa asinakulibala malunga nobulembu. Ezi, nangona zineempawu ezahluke kakhulu kwezo ze-cactus okanye i-rose bush umzekelo, zikwangabantu bezityalo. Kwaye ezo zinobungakanani obukhulu, ezinje nge I-Nereocystis luetkeana okanye i-kelp enkulu, nayo ine-stipe.

Sisakhiwo esixhasa iiframu, kwaye sinokufikelela ngaphezulu kweemitha ezingamashumi amathathu. Ke ngoko, bubulembu obenza amahlathi elwandle, ngakumbi kunxweme lwePasifiki.

Ngaba amakhowa anestipe?

Ayizizo zonke, kodwa ewe. Ifungi yosapho lweAgaricaceae (Agaricales), njengaleyo yohlobo amanita, Yiba nesakhiwo esixhasa umnqwazi okanye ipileo. Esi siqu saziwa njenge stipe, kwaye umbala waso uyahluka ngokodidi, nangona olona luqhelekileyo kukuba lumhlophe. Ingakhula ukusuka kwi-2 kuye kwi-10 yeesentimitha ubude malunga, kwaye ihlala ililindrical kwaye ibhityile.

Njengoko ubona, zininzi iintlobo zeziteki: ezinye zingagqitha kwi-30 yeemitha ukuphakama, ezinye zincinci kakhulu, zinobude beesentimitha enye okanye nangaphantsi, kodwa umsebenzi wazo ucacile: udibanisa iinxalenye ezimbini nesityalo (u fungus ), ke ngokungathandabuzekiyo sesona sakhiwo sibalulekileyo banazo.

Siyathemba ukuba ufunde lukhulu malunga nabo, kwaye ukusukela ngoku kuya kubalula kuwe ukuba ubachonge, kuba inokukunceda kungekuphela nje ukuba ufunde banzi ngebhodan, kodwa uyile negadi yakho.
