Nyama tating'ono

Tating'ono nyama - gulu la zamoyo, womwenso kunja dongosolo. Izi zikutanthauza kuti iwo sangathe kwathunthu zimachitika Ufumu iliyonse. zamoyo Unicellular yodziwika ndi kupanda zimakhala mwadongosolo. nyama zonse cha gulu ili ndi mnzake palibe makhalidwe ofanana. Chinthu chokha chimene chimagwirizanitsa iwo - dongosolo losavuta.

Tating'ono nyama zambiri kakang'ono moti akhoza amangoona pansi simungathe kutiona. malo awo - yonyowa. Izi nthaka ndi madzi, komanso thupi la munthu, nyama. Onse a iwo mwanjira ina mothandizidwa ndi zipangizo zosiyanasiyana ndinazolowera zikhalidwe zosiyanasiyana. Mu malo oyamba - ndi mtundu wa thupi. Iye sangakhale ndi omveka bwino zikusintha, ndipo mukhoza M'malo mwake, kukhala streamlined, ngati spindle kapena elongated. Ndipo osiyanasiyana chosokonekera: zozungulira, translational, rotational, wachiphamaso amaganiza. Nyama zina zokhala ndi selo imodzi ndi chipolopolo kunja, ndi zina, amene amakhala pansi pa madzi - zophuka zachilendo.

Selo imene thupi wapangidwa ndi zamoyo izi anyamula kwa wina ndi mtima angapo. Chipolopolo kapena chabe Kakhungu kapena wandiweyani, angathe yaitali pellicle Tambasula.

Mphero unicellular chamoyo kudzera prolegs zosiyanasiyana cilia, michirayo imakhala yosiyanasiyana. Iwo amvetsera mmene zinthu zina monga kusintha kutentha, kuunikira, kupezeka kwa mankhwala.

Tating'ono nyama kupeza chakudya m'njira zosiyanasiyana. Choncho, pa phagocytosis outgrowths cytoplasm adani particles olimba chakudya. Pinocytosis chikuchitika mu magawo angapo: choyamba, pamwamba pa khungu lonse likuthandiza madzi kenako kungolandira mabuku m'menemo, limazipukusa ntchito michere m'mimba, amene anadzazidwa vacuoles. M'kati mwa losavuta (Chlorella) ndi chloroplasts kuti ntchito dzuwa zingabweretse organic kuchokera ku zipangizo zochita kupanga.

Komanso, padziko lonse thupi nawo mpweya kuwombola losavuta: zitamuchitikira kunja kwa mankhwala kuwola ndi madzi owonjezera.

nyama chulukanani tating'ono ndi kugonana, ndi asexually. Izo zimatengera zinthu zimene iwo alipo. Asexual kubalana amapezeka kwambiri. Choyamba anawagawa magawo angapo phata, kenako nambalayi zidutswa za wagawanika ndipo cytoplasm. Choncho, munthu wa thupi pulayimale analandira angapo (osachepera awiri).

Mu kubereka kumafuna akazi ndi amuna. Kapangidwe awo ndi kukula zosiyanasiyana ndipo zikhoza kukhala chomwecho. Chifukwa cha pophatikizana anapanga awo zygote kenako imabereka asexually kale yawoyawo. Zimachitika kuti anthu pokhudzana, kufotokoza particles mtima. Pankhaniyi, zygote si anapanga.

Pamene mikhalidwe subala wabwinobwino kumodzi, thupi lawo n'lozungulira, yokutidwa ndi chipolopolo wandiweyani. Choncho chotupa aumbike. Kamodzi zinthu bwino, thupi kumasulidwa ku filimu wakuda ndi amayamba kutsogolera moyo nthawi zonse.

Amakhulupirira kuti nyama tating'ono poyamba anaonekera mu njira ya kusanduka Padziko Lapansi. Akale kwambiri ndi archaea ndi mabakiteriya. Iwo amafanana m'njira zambiri (mwachitsanzo, kusowa pachimake, pamaso pa mphete khromozomu), pachifukwa ichi, asanayambe anatchula gulu lomweli. Koma sayansi yamakono watsimikizira kuti archaea ndi peculiarities awo mu dongosolo, ndipo zayambika njira yosiyaniranapo. Ngakhale komanso ovuta m'kagulu, monga kale. chakuti iye anali asanamvepo wamkulu mu zasayansi archaea, ndipo apezeka pa kusanthula zitsanzo anatengedwa kuchokera ku malo kumene amakhala.

Single tating'ono zamoyo - ulalo, popanda zomwe n'zosatheka kumaliza biocoenosis. Ndipotu, kudya nyama ambiri, amene okha chakudya ngakhale kwa chiwerengero cha anthu a dziko lathu.
