Amoeba Proteus, kwendawo ezihlala kuyo, ikakhulukazi isakhiwo kanye nokusebenza

Amoeba Proteus nibonakala kuyinto cell kuhlobene uhlobo lenyama, rhizopods ekilasini, noma okunye bebizwa sarkodovyh. Sinenkosi pseudopodia, kukhona izitho which they ukuhambisa futhi bamba ukudla. igobolondo Okuwugqinsi kumaseli ulahlekile ngokuqondene lapho amoeba ukushintsha kalula ukuma. Ikhava yangaphandle - mncane kakhulu ulwelwesi cytoplasmic.

Amoeba Proteus isakhiwo.

I amoeba kakhulu nje wahlela. Omunye elula eziphilayo nezidalwa. It has no skeleton. Amoeba Proteus uhlala ezansi amadamu ahlukahlukene odakeni. Kukhona into eyodwa: kule amadamu kuphela angenasawoti: ichibi, emseleni, njll Uma ubheka ke, kwaba sobala ukuthi yinhlama grey esobala ayinakho ukuma njalo. Igama lalesi kokuba elihunyushwa ngokuthi "iyashintsha". amaseli umzimba akhiwa sonke isikhathi unyawo amanga, ngenxa yokuthi ukuthi cytoplasm ageleza eya ngapha nangapha. Ubukhulu yinhlama kungenzeka okungenani 0.2 mm okungenani 0.7 kwangu. Organelles - pseudopodia lula ukuhamba kwalesi sidalwa amancane. I traffic kancane kakhulu, kufana ukugeleza isikhwehlela obukhulu. Phakathi ukunyakaza amoeba sihlangana ezahlukene eziphilayo owumphumela ezifana ulwelwe nama-bacterium. It izimboze kubo nokuthi ukumunca cytoplasm abo, ukwakha vacuole wokugaya ukudla.

Amoeba Proteus cytoplasm inike enzyme ethize ekugayeni ukudla. Kukhona inqubo ukugaya intracellular. ukudla uyiphekwa ewuketshezi faka cytoplasm uqobo, futhi ukudla undigested ezisalayo - zikhishwa. Le ndlela avalele bhala libizwa phagocytosis. Esikhathini komzimba amoeba iziteshi ezicashile lapho ketshezi ingena emzimbeni cell. Le nqubo ibizwa ngokuthi pinocytosis ezaziwayo. Iyatholakala eyodwa vacuole, ukuxosha ngokweqile imikhiqizo ketshezi out. Ibizwa ngokuthi i-vacuole contractile. Ungena ukuhlukana enaleni njalo ngemizuzu emihlanu. Ngo endoplasm has uhlamvu. Lokuzaliswa kwenzeka kanje: leli ngqamuzana liyahlukana e ezimbili, okusho asexually.

Njengoba amoeba izehlukanisa imiphumela ebuhlungu kusukela ngaphandle.

Uma kukhona kwezimo ezingezinhle sokuba khona lokhu umzimba, ezifana echibini omiswe, ukuphola amanzi ku ichibi futhi omunye amoeba Proteus njalo sifuna Nqamula uqobo kuzo. Udvweba organelles yayo, kuyahlanganiswa igobolondo kabili futhi ngaleyo ndlela yakha simila. Ngaphansi kwezimo ezikahle, isib, ehlobo eshiya amoeba simila. Simila eyalo umoya, ngakho amoeba Proteus indaba. lokhu ukuphefumula isidalwa kwenzeka kuwo wonke umzimba wakhe ebusweni, ie, emangqamuzaneni omzimba. Amoeba ubamba umoya-mpilo okhona ku-i osebenzelana aqueous, kukhipha-carbon dioxide. Nge-mpilo izakhi ukubola zibe compounds lula. Kubantu nasezilwaneni abaningi, ikakhulukazi esiswini zabo, i amoeba siphile nezinambuzane. Omunye abamele lezi izimuncagazi iyona amoeba uhudo. It feeds wamathumbu izinhlayiya (ubhujiswe), kanye amangqamuzana abomvu egazi. Kuyinto agent causative of isifo esithathelwanayo, okuthiwa uhudo amoebic.

iziphetho:

- amoeba Proteus nesihudo amoeba kukhona izilwane owumphumela. Move nge organelles-prolegs basonta rhizomes;

- ekilasini rhizopods kufana ulwelwe, okhombisa nobuhlobo babo;

- ekhasini udaba eziphilayo akuzuzayo nezinye izitshalo, noma ezinye izinto eziphilayo elula, okuyinto eveza umahluko phakathi kwabo kusuka ulwelwe amoeba.

Amoeba - nakuba elula, kodwa wonke umzimba uyakwazi ukuhola khona ezimele.
