Keji - ndicho upenyu!

Kana unoyeuka zvipenyu Chokwadi, sero - a STRUCTURAL uye dzichipfekeka chairema dzavamwe vapenyu muviri. Tingatii, kunyange kana paine zvinenge vakadaro inomiririra sero rimwe chete. Saka zita - celled. Asi muviri mhuka uye vanhu anongoti incredible siyana emasero. Ngationei kuyeuka maumbirwo masero.

Sero rimwe nerimwe riri mumuviri wedu akapoteredzwa chaiwo unodzivirira unhani, unonzi "Kamudzira". Inside ndiyo tsanga. Zvinokosha kucherechedza kuti kwete masero zvose muviri zvine nuclei. Somuenzaniso, sezvo masero ake matsvuku vanorasikirwa kuibvisa ravo. In mumasero striated tsandanyama, nekusiyana, hakuna chinoumba, asi akawanda. Sezvataurwa pamusoro apa, pane chinokosha sero yeplasma membrane. Its basa chikuru - kuona kubata pamwe masero pedyo uye zvakatipoteredza. Sezvo kuburikidza Kamudzira kwamakamuri zvose basa metabolic zvigadzirwa, uyewo kuwana zvakakodzera kuti chakaipa nokushanda kwenhengo mhaka, tinogona kutaura kuti zviri - chimwe chezvinhu zvinokosha zvinoriumba. Kusunungurwa fuma uye nekusiyana, goho ravo riri kudivi nheyo diffusion, kana nokuda tichishingaira chokufambisa kuburikidza chaiwo makwara.

Core - ndeimwe rokuti inokosha pamusoro STRUCTURAL chairema ane muviri mupenyu, anonzi "masero." Uyu duku idenderedzwa organelle, iyo inoita basa rinokosha mune mutemo cellular urongwa, uye kunewo anodiwa mashoko magene. Musimboti ane pachake Kamudzira rayo, iyo inodiwa kuti kuparadzanisa kubva cytoplasm.

Kuzosimbisa kukosha musimboti muupenyu sero, masayendisiti aiitisa kuedza dzakawanda. Chaizvoizvo kwavo kuri chokuti panguva amoebae uchishandisa inokosha tsono rakabvisirwa musimboti. Mazuva mashoma pashure peizvi evanhu amoeba akafa. Kwete, haana kurega kudya, asi wakagara rakapotsa pezvakaitwa zvose. Chokwadi, tinogona kufungidzira kuti amoeba kufa nokuti vakaperekedza "amabasa", asi akadzokorora ruzivo, umo chinoumba haina kubviswa, asi kungotaura chinoita yakaratidza kuti amoeba somugumisiro kukanganiswa kwakadaro hakuiti kufa.

organelle Next, pasina iro hakuna hahugoni kuvapo foni - ndiko mitochondria. Zvinonzi takapoteredzwa kaviri membrane. The chikuru basa sostavlyayushey ichi chero masero - ATP kugadzirwa nenzira Erekitironi chokufambisa uye oxidative phosphorylation pezvakaitwa. Pasinei chokwadi kuti mitochondria vane DNA yavo, mapuroteni yaro encoded nokuti DNA, izvo zvinobva cytoplasm. Akapiwa chokwadi kuti simba kunokosha muupenyu uye zvakakodzera kushanda masero ose, kukosha organelle ichi zvinova kusimba kukosha zvakadai chivakwa sezvo foni. Sechivako nomumwe zvakaenzana mitochondria uye haana kusiyana. Kune membranes mbiri, yokutanga iyo wokunze uye anoshanda kuti zviparadzanise mitochondria kubva cytoplasm. Wechipiri - yomukati, rokunze akaparadzaniswa intermembrane inosvika mitochondria uye anodzivirira zviri risapinda kubva kunze.

Mumwe Sero organelles ndicho chatinonyanya kukosha, saka zvakaoma chaizvo kuziva zvisingakoshi uye zvakakodzera. Keji - ndicho upenyu!
