Cage: definition, tsarin

Cage - a tsarin da morpho-aikin naúrar na duk rayayyun kwayoyin halitta. Rarrabe unicellular da kwayar kwayoyin.

Mai Kwayoyin suna da wadannan tsarin: a shafi na'ura, da tsakiya da kuma cytoplasm tare da wasu gabbansa. Inuwõyi iya wakilta cytoplasmic membrane da cell bango. A tsakiya kuma wasu gabbansa yana da kawai eukaryotic cell, ma'ana wanda ya bambanta daga prokaryotic.

Kwayoyin na kwayar kwayoyin samar da wata masana'anta, wadda a nuna wani bangare ne na gabobin da kuma sashin jiki tsarin. Sun zo a cikin daban-daban masu girma dabam da kuma za su iya bambanta a tsari da kuma aiki. Don rarrabe waɗannan kananan Tsarin iya zama kawai da hange.

Mene ne wani cell Biology. Definition na prokaryotic Kwayoyin

Kwayoyin, kamar kwayoyin cuta, suna da wani Firayim misali na prokaryotic kwayoyin. Wannan cell irin ne mai sauki a cikin tsarin, watau. K. ba ya nan a kwayoyin cuta da sauran core cytoplasmic wasu gabbansa. Hereditary bayanai da aka dauke a cikin kananan kwayoyin halitta na musamman tsarin - nucleoid da organelle ayyuka aiki mesosoma wanda aka kafa ta invagination na jini membrane a cikin cell.

Abin da sauran siffofin yana da wani prokaryotic cell? A definition furta cewa gaban cilia da flagella kuma shi ne halayyar kwayoyin. Wannan ƙarin motor naúrar ne daban-daban a cikin daban-daban kungiyoyin na kwayoyin: wani yana daya kawai flagellum a wani akwai biyu ko fiye. A ciliates flagella akwai, amma akwai cilia duk kan periphery daga cikin cell.

Hada wasa a babban rawa a cikin rayuwa da kwayoyin cuta, watau. A., Prokaryotic Kwayoyin ba su mallaka da wasu gabbansa da suke iya tara da zama dole abubuwa. Inclusions ake samu a cikin cytoplasm da kuma a cikin wannan kompaktiziruyutsya. Idan ya cancanta, da kwayoyin cuta na iya amfani da wadannan tara abubuwa don nasu bukatun, domin ya kula da al'ada aiki.

eukaryotic Kwayoyin

Eukaryotic Kwayoyin suna evolutionarily karin ci-gaba kamar yadda idan aka kwatanta da prokaryotic Kwayoyin. Bã su da dukan hankula da wasu gabbansa da tsakiya - cibiyar da ajiya da kuma watsa kayyade bayani.

A definition of "cell" daidai ya bayyana tsarin da eukaryotes. Kowane cell an rufe tare da cytoplasmic membrane, wanda aka wakilta bilipidnym Layer da kuma sunadarai. Located a saman glycocalyx, wanda aka kafa ta glycoproteins, kuma ya aikata aikin da tsoka mai amsa sigina. A shuka Kwayoyin ma asirce wani cell bango.

A cytoplasm na eukaryotes wakilta colloidal bayani, wanda ya ƙunshi wasu gabbansa, cytoskeleton kuma daban-daban inclusions. Daga cikin ruwan dare wasu gabbansa endoplasmic reticulum (m, m), da Golgi na'ura, lysosomes, peroxisomes, mitochondria da plastids na shuke-shuke. Microtubule cytoskeleton wakilta, microfilaments kuma matsakaici microfilaments. Wadannan Tsarin samar da wata firam, da kuma shiga a cikin division. Direct rawa a cikin wannan tsari ne da cibiyar, wanda shi ne wani dabba cell. Kafiya, gano da cytoskeleton da cell cibiyar a cikin kauri ne kawai zai yiwu tare da yin amfani da iko na zamani hange.

Core - dvumembrannaya wannan tsarin, da abun ciki na wanda aka gabatar karyolymph. Ya ƙunshi wani chromosome hada da DNA daga duk Kwayoyin. Kwaya ne alhakin kwafi na genes na kwayoyin da kuma iko da rarraba, saukarwa a lokacin mitosis da meiosis amitosis.

Non-salon salula siffofin rai

Mene ne wani cell a ilmin halitta? A definition wannan lokaci za a iya amfani da su bayyana tsarin da kusan duk wani kwayoyin, amma akwai ban. Saboda haka, ƙwayoyin cuta ne babban wakilan da ba-salon salula rayuwa siffofin. .. Su kungiyar ne quite sauki, cewa shi ne da ƙwayoyin cuta - suna dauke da kwayar cutar jamiái da suke a cikin tsarin dauke da kawai biyu kwayoyin aka gyara: DNA ko RNA da kuma mai gina jiki gashi.

Ƙwayoyin cuta ne parasites peculiar dabba da shuka Kwayoyin. Bayan shigar azzakari cikin farji cikin rundunar cell cutar saka a cikin nucleic acid a DNA core, bayan da ta fara kira na da kwayar cutar kwayoyin halittu. A sakamakon haka, rundunar cell zama irin factory domin samar da sabon cutar gaɓũɓuwa, wanda ta haka ne kara da lambobi. Bayan da irin jan eukaryotic cell yawanci mutu.

A kwayoyin ma sha wahala daga cutar harin, wanda sune rukuni na bacteriophages. Jikinsu yana cikin siffar wani dodecahedron, da kuma "allura" nucleic acid a cikin kwayan cell auku via caudal aiwatar wakilta contractile cover, ciki shaft da kuma muhimmi lamina.
