I amoeba - iyisilwane ejwayelekile owumphumela

I amoeba - imelele izilwane unicellular, bakwazi ngenkuthalo ukuhambahamba ngosizo organelles ethize ezikhethekile. Izici isakhiwo nokubaluleka la magciwane ngokwemvelo uyokwambulwa kulesi sihloko.

Simple Isici subkingdoms

Naphezu kweqiniso lokuthi elula banegama isakhiwo kwabo kunalokho xaka. Ngempela, omunye ngqamuzana elincanyana ukuthi ongenza imisebenzi yonke umzimba. I amoeba - lena ngenye ubufakazi obuphathekayo balokho. Lokhu umzimba, kuze 0.5 mm, uyakwazi ukuba sikwazi ukuphefumula, ukuhambisa, nande, akhule.

Ukunyakaza kwabantu noma izithunzi elula

eziphilayo owumphumela ukuhambisa esebenzisa organelles ekhethekile. Ngo ciliates abizwa ngokuthi cilia. Cabanga nje phezu cell kuze kufinyelele 0.3 mm athambekele-15 ezinkulungwane zalezi organelles. Ngamunye wabo kwenza ukuhamba pendulum.

Euglena has a msila. Ngokungafani cilia, senza ezinyakazayo Helical. Kodwa ihlanganisa lezi organelles siwukuthi bangamalungu unomphela iseli amaqhubu.

amoeba ukunyakaza ngenxa prolegs khona. Zibizwa ngokuthi pseudopodia. Lokhu-non-unomphela iseli isakhiwo. Ngenxa kuyaqina we ulwelwesi kungase zimiswe kuphi. cytoplasm Okokuqala ihamba phandle kanye namafomu zeziboya. Khona-ke kulandela inqubo reverse, pseudopodia iqondiswe esitokisini. Imiphumela iba yinhlanganisela yokukhandleka ukunyakaza kancane amoeba. I prolegs khona isici esasenza lokhu omele subkingdoms unicellular.

amoeba Proteus

I amoeba - kuyinto umzimba ukuthi uthola igama layo kusukela umlingisi zamaGreki - Proteus, ngoba wakwazi ukushintsha ukubukeka kwabo. Lesi silwane kungekho nto enemibala emihle owumphumela ukuthi ingatholakala fresh amanzi, inhlabathi, abantu kanye nezilwane. Lokhu eziphilayo heterotrophic, okuyizindawo wokudla -celled ulwelwe nama-bacterium.

isakhiwo i amoeba

Zonke amaseli lenyama eukaryotic - aqukethe ikhenela. Izidumbu amoeba, kunalokho organelles yayo ukufeza zonke izinqubo zokuphila. Pseudopods behileleka hhayi kuphela ukuqaliswa womgwaqo, kodwa futhi kunikeza amoeba inqubo yokudla. Ngosizo lwabo isilwane oluncane ihlanganisa izinhlayiyana zokudla, okuyinto lizungezwe ulwelwesi kanye ngaphakathi engqamuzaneni. Lena inqubo kumiswa vacuoles wokugaya ukudla lapho cleavage kwenzeka izinto. inqubo okunjalo kwezinkolo kubizwa ngokuthi ukumuncwa particulate phagocytosis. ukudla Undigested ume kuphi ulwelwesi cell.

I amoeba, njengazo zonke elula, ayinakho organelles ezikhethekile zokuphefumula kokwenza exchange igesi ngokusebenzisa ulwelwesi.

Kodwa inqubo yenziwa ukulawulwa ingcindezi intracellular usebenzisa vacuoles contractile. Okuqukethwe usawoti imvelo ingaphezu kwe ngaphakathi emzimbeni. Ngakho-ke, ngokuvumelana imithetho yemvelo, abaseGibithe bayakunengwa ngukuphuza amanzi agelezele amoeba - kusuka esifundeni lokuhlushwa ngaphezulu ukuze aphansi. vacuoles Contractile lokulawula le nqubo ndawonye amanzi imikhiqizo umzimba.

Ukuze amoebae esingokwemvelo ukukhiqizwa kabusha asexual by cell division e ezimbili. Lona bakudala kunazo zonke izindlela eyaziwa Nokho, inikeza ukulondolozwa olunembile futhi ukudluliswa kolwazi sitholwa njengefa. Uma lokhu kwenzeka okokuqala Ukuhlukaniswa nucleus organelles, bese ukwehlukana odongeni cell.

Lokhu umzimba elula uyakwazi ukuphendula isenzo yizici zemvelo: ukukhanya, izinga lokushisa, ushintsho Ukwakheka kwamakhemikhali kwesigubhu.

kwezimo ezingezinhle oluncane adluliselwe ku nginesimila. iseli okunjalo siyeke ukunyakaza, kunciphisa okuqukethwe amanzi, idwetshwa unyawo zamanga. Futhi yena embozwe igobolondo kanzima kakhulu. Lena simila. Ngaphansi kwezimo ezikahle amoeba ushiye izinhlumba futhi wabe izinqubo evamile yokuphila.

uhudo amoeba

I amoeba - akuyona nje owakhileyo ayinangozi angenasawoti, okuyinto ingxenye plankton. Omunye nohlobo lwayo, okuthiwa uhudo amoeba, uhlala mafutha anciphisa isikhala esingaphakathi emathunjini womuntu. Lapha, i-umzimba owumphumela kuyimpilo yisinanakazana, ukudla amagciwane. Engena phakathi odongeni emathunjini, amoeba ebhubhisa lwamafinyila ulwelwesi amaseli bese amangqamuzana abomvu egazi - amangqamuzana abomvu egazi. Ngenxa yalokho, lapho phezu isilonda. Bekanye undigested izinsalela ukudla izilwane yisinanakazana ukuphumela phandle. Itheleleke nge uhudo kungaba ukusetshenziswa kwamanzi eluhlaza, izithelo ezingahlanjiwe nemifino, hhayi ogcina imithetho inhlanzeko yomuntu siqu.

Ezinye izinhlobo zayo eziningi zalezi nje ukudlala indima eqakathekileko nemvelo. Amoebas iwumthombo ukudla kwezilwane eziningi, izibungu okungukuthi inhlanzi, izimpethu, molluscs, ezinamagobolondo. Bona ukuhlanza amanzi ahlanzekile kusuka amagciwane kanye abolile ulwelwe, kukhona kube inkomba yokuthi indawo ihlanzekile. amoebae Testate iqhaza kumiswa limestone kanye wokulinganisa imali.
