The mamiriro masero evanhu: nyore kuti zvakaoma

Sero romunhu rakasiyana nemamwe mhuka sechikamu mumuviri, kana tikafunga chete mukuru nemamiriro urongwa. Ongorora nemamiriro masero kwevanhu, cytology akataura zviviri zvakasiyana zviri basa - musimboti uye cytoplasm. Daily mabasa, kuona kugara zvinodiwa chairema zvose zvipenyu zvose basa cytoplasm.

All chaizvo mabasa akadai marwadzo ari tsandanyama masero kana tsinga chiratidzo yedzimudzangara zvakare anoitwa kunoshandisa cytoplasm. Saka, marudzi akasiyana-siyana ari cytoplasm masero yakasiyana. Uye pano chete mune sechivako musimboti kunyange siyana kwemarudzi.

Sechivako sero musimboti zvakakwana noruvara ari mupenyu vamapoka mhando dzakasiyana. Kune clumps ose chromatin uye nucleoli. Chromatin haisi makemikari remubatanidzwa rinongova DNA "yakazara" mamiriro. The chromatin zvakare vachitova RNA uye mapurotini, histones.

Musimboti zvinokonzerwa dzeraundi kana denderedzwa. Asi pane oblong, uye akaparadzaniswa nevanhu transverse constrictions (sezvo zvinoitika neutrophils). Tichitarisa mamiriro kwamakamuri dzevanhu, zvinofanira kucherechedzwa kuti kune yose Kamudzira maitiro uye interphase (kunze weboka), kuti tsanga anogara akapoteredzwa hamvuropu renyukireya. The goko ane mwena inonzi zvenyukireya pores. Kuburikidza navo chinoumba uye kubva tiri macromolecules.

Inner makirisito ezvinhu akasiyana chaizvo kubva cellular ezvinhu, izvi inopiwa dzakaonda diaphragms pores hunoita chete zvinodiwa fuma kupinda musimboti. Saka tsanga anokurukura pamwe cytoplasm kwemakemikari mashoko. The nucleolus aumbwa rRNA zvakakodzera kuti sero chokuwanziridza. nucleoli kazhinji batanidza mumba mumwe uye maikorosikopu kuona rimwe nucleolus guru.

Nuclear muto makemikari anoumba - mapuroteni colloidal mhinduro, izvozvo zvakaipa yakasvibiswa mu kugadzirira Erekitironi maikorosikopu, uye anozviratidza sechiedza nzvimbo photomicrographs. Zviri akanaka sparse ezvinhu umo akwanise ari diffusion pamusoro metabolites, uye masero zvinhu zvinogona kufamba nokukurumidza.

Uye chii cytoplasm? In wake "mabasa" kwete chete inosanganisira sangano wokuberekana, nezvose iye anogona kuita. The mamiriro masero dzevanhu zvokuti hwaro upenyu - oxidation, kuitika cytoplasm. Inoitwa zvivako zvakawanda duku, akadana organelles, kana organelles, nomuenzaniso pamwe zvitunha muviri guru.

organelles Vazhinji Kamudzira mamiriro. Kwete chete membranes zvine vakasununguka ribosomes, centrioles, cilia uye flagella (zvose mhando nhatu organelles ine microtubules) uyewo fibrillar chivako (microfilaments uye fibrils).

Sechivako muchitokisi kwevanhu Kamudzira, pfungwa, kureva, vose madhipatimendi dzakavharika membranes. Mitochondria Somuenzaniso, kazhinji akaumbwa maviri akaturikidzana ose membranes, apo kwetunhu simba mamorekuru - ATP somugumisiro siyana pamusoro cellular afemeruke. Mitochondria nevamwe, nokuti tupukanana kuti vava symbionts. Vane pachavo genome kwavo, uye kazhinji rakanaka akazvimirira. Zvinofungirwa kuti vari zvizvarwa utachiona.

Ribosomes, izvo dzimwe nguva aibatanidza mu polyribosomes, mubasa iri kwetunhu mapuroteni, zvakafanira kuti cytoplasm. Uye zvinokosha zvikuru, kwete chete kuvaka zvivako, asiwo kuti varambe pakuenzanisa osmotic nevamwe chakaipa.

The endoplasmic reticulum ndiyo matema, zviri interconnected. Vamwe vavo vari ribosome. A puroteni kuti synthesized navo, asingagari kuyangarara ari muto of cytoplasm - the cytosol, uye riri kure sero vasati ruminant kana kuti kushandiswa pane zvimwe zvinodiwa.

Golgi midziyo - chinhu chakafanana pamurwi muhomwe. Kune vari vaunganidza uye arongwe zvakasiyana zvinhu. Mapuroteni pano wana yaro yokupedzisira marongerwo uye aumbwa pano lysosomes.

Achitaura pamusoro lysosomes. Vanoparadza pasingadiwi muchitokisi zvinoriumba, kana chinhu chakaipa navo, zvino kuva zvirwere okuchengetera. Pakafa sero, vari kuparadza zvakatipoteredza kunyange akafa akafa zvipenyu zviyero, kwete chete akazvifukidza.

Sechivako masero mapenyu akasiyana nemamiriro vakafa pakutanga kuti anouya akafa karyolysis - the disintegration of neerekitironi sero zviri pashure kugaya resorption lysosomal membranes.
