Iimpawu ezingundoqo lomzimba lwesilwanyana

Phakathi ezahlukeneyo eziphilayo, izilwanyana zinendawo yazo. Abameli beli ubukumkani zininzi kwaye zahlukene. Euglena oluhlaza, amanzi hydra, uhlabamanzi, ubuhle, ichibi frog, idada mallard, ibhere elimhlophe ... Kuphantsi kweziphi izizathu ukuba bamanyene ubukumkani? Ziintoni iimpawu eziqhelekileyo isilwanyana? Iimpendulo zale mibuzo kweli nqaku.

iimpawu ezingundoqo lomzimba lwesilwanyana

Izilwanyana kakuhle zonke iindawo zokuhlala. Aphile emhlabeni kwaye umhlaba, umoya, amanzi, kunye neentlobo ekumfimfitheni - kwezinye izinto eziphilayo. Eqhelekileyo kubo isakhiwo zeselula ubunye ubume umchiza, uhlobo lokutya, ingakumbi ukukhula, ukutya, ukukwazi ukuhamba. Iiyantlukwano ezi mpawu zingumvuka weemeko ezahlukeneyo: iqondo lobushushu amanzi okanye umoya, ubukho amandla elanga, imali kunye nohlobo lokutya.

indlela amandla

Iimpawu isilwanyana ngokuyintloko ezimiselwe supply ngendlela. Ngenxa yesi sizathu, ukuba heterotrophic. Oku kuthetha ukuba izilwanyana nako ukuziphelisa kuphela umbandela ogqityiweyo. Ukuba luthathe ukutya ngeendlela ezahlukeneyo. Hi xikombiso, amarhamncwa ukuhlasela lixhoba labo, kunye saprotrophs ukubola umcimbi efile organic. izilwanyana olwaye lwamfimfitha bondliwa ezinye izinto eziphilayo. Indlela emi ngayo ukutya kuxhomekeke iimpawu noshowo amalungu ezahlukeneyo. Umzekelo, amarhamncwa kakuhle canines ngophuhliso nezikrekrethi ukuba abekho kunye endaweni zokusika ezongezelelweyo.

Ingakumbi izinga yeselula

iiseli Animal nabo waphawulwa ngezinto eziliqela lweempawu. Okokuqala kwaye kwephambili kukungabikho eluhlaza plastids chloroplasts, nto leyo ebonisa nokungakwazi kwabo umBoniso. Udonga seli iqulethe iikhompawundi wekhabohayidreyiti kunye lipids kunye iiprothini kunye glycocalyx thaca. Loo sisincoko yemichiza yenza luthambe kunye namandla kobume. iimpawu ezininzi isilwanyana ebangelwe ebusweni ngumongo kwi icytoplasm. Le zofuzo siqulathe organelle kwaye inxaxheba kwinkqubo ngokucandeka. izilwanyana kwiseli enye, umz, euglena, ciliates, amoeba, lokuyivelisa ngokwahlula phakathi ezimbini. Bona azinamgaqo vacuoles uzibekele izinto. Ezi zithinteli enze umsebenzi ukwetyisa kwamasuntswana ukutya kunye kukhuthaza izixa ngokugqithiseleyo ityuwa namanzi.

motion

Iimpawu kwesilwanyana njengoko kumiselwe ubuchule babo ukuhamba ngomdla emajukujukwini. Oku uyakwazi kubalulekile ukubonelela izakhiwo ezizodwa. Izilwanyana elula na intshukumo organelle. Baya angamelwa isiliya, misila okanye pseudopods. Kwizilwanyana multicellular lo msebenzi wenziwa inkqubo musculoskeletal. Siqulathe amathambo, izihlunu kunye nemisipha. Bangamalungu izilwanyana kungenzeka ukuba ilungiswe. Character olukhulu ixhomekeke ubukhulu becala iimpawu zokuhlala eziphilayo. Ngoko ke, iintaka imilenze ephezulu similise amaphiko, kunye nezilwanyana ezanyisayo zasemanzini - in amaphiko. Kuyo nayiphi na imeko, zonke izilwanyana ngenkuthalo ihamba emajukujukwini zikhangela ukutya kunye neemeko ezingcono zokuphila.

ukukhula

Ukukhula izilwanyana ulinganiselwe. Oku kuthetha ukuba utshintsho oluninzi kwenzeka kuphela ixesha elithile lobomi, uze emva koko uyeke. Umzekelo, iikati nezinja zikhula ukuya kwiminyaka-3, kwaye umntu - ukuya 20. utshintsho Quantitative zisoloko zikhatshwe qualitative - nophuhliso. Oku wabonakaliswa ubuxhakaxhaka ukuhamba kweenkqubo ezahlukeneyo nokomzimba.

Ngenxa yoko, iimpawu uphawu isilwanyana - it indlela unikezelo heterotrophic, ukukwazi kwintshukumo esebenzayo, ukukhula elilinganiselweyo. Ngayo kwezi zizathu umiselwa ngokuhlelwa kunye nokunikezelwa ngendlela ezi zidalwa.
