Celled mhuka

Celled mhuka - a chikamu zvipenyu, inomira kunze hurongwa. Izvi zvinoreva kuti haagoni kunzi zvachose chero chaiyo umambo. Unicellular zvinenge dzinoratidzwa kushaya zvikuru yakarongwa munyama. mhuka yose vari boka iri pakati pavo hapana zvakafanana unhu. Chinhu bedzi kunovabatanidza - nyore marongerwo.

Celled mhuka kakawanda muduku kuti vanogona kuonekwa chete nemaikorosikopu. dzinogarisana - nyoro. ivhu iri uye mvura, uyewo muviri, mhuka. Vose nzira imwe kana mumwe uchibatsirwa siyana mano dzakashandisa mamiriro siyana. Pakutanga - chiri muchimiro muviri. Haafaniri kuva miganhu zvakajeka, dzichichinja, uye anogona nekusiyana, anofanira streamlined, akafanana chokurukisa kana elongated. Uye marudzi ose symmetry: TOUR, translational, rotational, kaviri madziro. Vamwe mhuka dzisina celled vane goko kunze, mumwe, avo kuti kurarama pakadzika pasi mvura - kujairika growths.

Sero umo muviri rinoumbwa zvipenyu izvi ingasanganisira kubva mumwe nuclei wandei. Shell kana kunongova Kamudzira kana gobvu, vaikwanisa yakareba Stretch pellicle.

Zvigayo unicellular muviri Via siyana cilia prolegs, flagella. Naivowo sei matambudziko nechitarisiko zvinhu zvakadai nokuchinja tembiricha, chiedza, Kuwanikwa makemikari.

Celled mhuka zvokudya nenzira dzakasiyana. Saka, panguva phagocytosis outgrowths cytoplasm kubatwa yakasimba tudonhwe chikafu. Pinocytosis kunoitika mumatanho akawanda: kutanga, pemvura sero yose inobudisa mvura uye kuchipedza zvinhu zviri mukati, kurongedza navo achishandisa zvomudumbu makemikari, izvo zvinogutswa vacuoles. Inside vamwe nyore (Chlorella) ndiko chloroplasts kuti kushandisa photosynthesis anogona kubereka Organic kubva inorganic zvinhu.

Uyewo, pose yose muviri mukupara gasi Exchange nyore: nepa kuti kunze kuora zvinhu uye mvura nekusazvidzora.

mhuka uwande-celled uye pabonde, uye asexually. It zvinoenderana mamiriro ezvinhu umo zviripo. Asexual kubereka kunoitika kudaro. First rakakamurwa akawanda zvikamu neerekitironi, uchiteverwa chete nhamba zvezvimedu yakakamurwa uye cytoplasm. Saka, mumwe zvokutanga muviri vakawana dzakawanda (zviviri).

In dzepabonde kubereka kunosanganisira vakadzi uye vanhurume. Chimiro chavo uye kukura dzingasiyana, uye zvingava zvakafanana. Somugumisiro kwavo batanidzo kuumbwa zygote, iyo zvino reproduces asexually kare varidzi. Zvinoitika kuti vanhu vaaisangana, kupanana nuclei inoramba. Panyaya iyi, kuti zygote hauna kuumbwa.

Kana mamiriro ezvinhu vari haakonzeri dzose upenyu huri nyore, muviri wavo rakatenderera, akazadza batana nevamwe. Saka chikofu aumbwa. Kamwe ezvinhu kuvandudza, muviri wobudiswa makobvu firimu uye anotanga kutungamirira chete mararamiro sekare.

Zvinofungidzirwa kuti mhuka imwe-celled kutanga akazviratidza mukufamba shanduka Panyika. Kupfuura kare ndivo archaea uye utachiona. Ndivo zvakafanana munzira dzakawanda (semuenzaniso, kushayikwa chinoumba, kuvapo mhete chromosome), nokuda kwechikonzero ichi, vasati akataura chete boka. Asi sayenzi yemazuva ano vakaratidza kuti archaea vane peculiarities dzavo marongerwo, uye kunge wakashanduka-shanduka ari siyanei nzira. Kunyange zvazvo ivo kuoma patsanura sakare. Chokwadi akanga asati akura murabhoritari archaea, uye akawanikwa panguva kuongorora ivhu kubva panzvimbo nekwavanogara.

Single-celled zvinenge - link, pasina pazviri pasingabviri kuti apedzise biocoenosis. Pashure pezvose, vodya mhuka dzakawanda, izvo pachavo zvokudya kunyange wandei Vagari redu.
