A amoeba - shi ne wani hali guda-celled dabba

A amoeba - shi ne wakilin unicellular dabbobi, iya rayayye matsar kusa da taimakon musamman na musamman da wasu gabbansa. Features na da tsarin da muhimmancin wadannan kwayoyin a cikin yanayi za a bayyana a cikin wannan labarin.

Simple Feature subkingdoms

Duk da cewa mafi sauki da sunan su tsarin ne wajen rikitarwa. Lalle ne, daya microscopic cell abin da yake iya yin ayyuka na dukan kwayoyin. A amoeba - wannan shi ne wani hujja da wannan. Wannan kwayoyin, har zuwa 0.5 mm, shi ne iya numfashi, matsawa, ninka, girma da kuma ci gaba.

The motsi daga cikin sauki

Single-celled kwayoyin matsawa ta wajen musamman da wasu gabbansa. A ciliates ake kira cilia. Just tunanin a kan salula surface har zuwa 0.3 mm an zubar game da 15 dubbai daga cikinsu. Kowace daga cikinsu da ke sa a Pendulum motsi.

Euglena yana da wani flagellum. A bambanci ga cilia, ya yi aikin helical motsi. Amma shi hadawa wadannan da wasu gabbansa ne cewa su ne m cell outgrowths.

amoeba motsi saboda gaban prolegs. Suna da ake kira pseudopodia. Wannan ba m sifar tantanin halitta. Saboda da elasticity na membrane za a iya kafa a ko'ina. Da farko cytoplasm motsa waje da kuma siffofin protrusions. Sa'an nan ya bi da baya da tsari, pseudopodia directed a cikin cell. A sakamakon haka ne jinkirin motsi na amoeba. A gaban prolegs ne a rarrabe wannan wakilin subkingdoms unicellular.

amoeba Proteus

A amoeba - shi ne kwayoyin da cewa samo sunanta ne daga wani hali a Girkanci mythology - Proteus, saboda ya ya iya canza su bayyanar. Wannan colorless guda-celled dabba da cewa za a iya samu a sabo ruwa, ƙasa, mutane da dabbobi. Wannan heterotrophic kwayoyin, wanda bauta wa a matsayin tushen abinci -celled algae da kwayoyin.

tsarin mai amoeba

All Kwayoyin suna eukaryotic protozoa - dauke da wani kwaya. Jikuna na amoeba, wajen da wasu gabbansa iya gudanar da duk matakai na rayuwa. Pseudopods suna da hannu ba kawai a aiwatar da zirga-zirga, amma kuma samar da wani amoeba ciyar tsari. Tare da su taimako celled dabba rufe abinci gaɓũɓuwa, wanda aka kewaye da membrane kuma a cikin cell. Wannan shi ne kan aiwatar da samuwar narkewa kamar vacuoles a wadda tsakiyan nonon auku abubuwa. Irin wannan tsari shine ake kira sha particulate phagocytosis. Undigested abinci tsaya ko'ina a jikin tantanin.

A amoeba, kamar duk sauki, yana da wani musamman na numfashi da wasu gabbansa yin gas musayar ta cikin membrane.

Amma tsari ne da za'ayi da tsari na kwayuka matsa lamba ta amfani da contractile vacuoles. The gishiri abun ciki a cikin yanayi ne ya fi a cikin jiki. Saboda haka, bisa ga dokokin kimiyyar lissafi, da ruwa zai gudana daga ƙarƙashinsu a cikin amoeba - daga yankin na mafi girma maida hankali ga ƙananan. Contractile vacuoles gwada wannan tsari kawo tare ruwa da wasu na rayuwa kayayyakin.

Domin amoebae muhimmi sake yiwuwar tohowarsu, ta hanyar salula rabo a cikin biyu. Wannan shi ne mafi m na dukan da aka sani hanyoyin, duk da haka, samar da cikakken tanadin da kuma watsa hereditary bayanai. Lokacin da wannan ya auku farko rabo daga cikin tsakiya, da wasu gabbansa, sa'an nan rabuwa da cell bango.

Wannan sauki kwayoyin ne iya amsa ga mataki na muhalli dalilai: haske, zazzabi, canji a sinadaran abun da ke ciki na tafki.

Wannan shi ne wani mafitsara. A karkashin sharadi gwargwado amoeba bar cysts kuma Saide al'ada rayuwa tafiyar matakai.

dysentery amoeba

A amoeba - shi ne ba kawai wani m mazauni na ruwa tare, wanda shi ne wani ɓangare na plankton. Daya daga ta jinsi wanda ake kira dysentery amoeba, na zaune a cikin lumen na mutum hanji. A nan, guda-celled kwayoyin ne a parasitic salon, cin abinci kwayoyin. Iya shiga a cikin hanji bango, amoeba halaka mucous membrane Kwayoyin da ja jini Kwayoyin - ja jini Kwayoyin. A sakamakon haka, akwai a farfajiya na miki. Tare da undigested abinci sharan parasitic dabbobi tafi a waje. Kamu da dysentery iya zama a cikin yin amfani da albarkatun ruwa, marsa wanki da 'ya'yan itatuwa da kayan marmari, ba lura da dokoki na sirri kiwon lafiya.

Mutane da yawa jinsunan wadannan kawai don taka muhimmiyar rawa a cikin yanayi. Amoebas ne tushen abinci na dabbobin da yawa, wato kifi larvae, tsutsotsi, molluscs, kananan crustaceans. Su tsabtace sabo ruwa daga kwayoyin da Rotting algae, suna da wani nuna alama na mai tsabta yanayi. Testate amoebae shiga a cikin samuwar farar ƙasa da alli adibas.
