比如細(xì)胞形態(tài)的多樣性、運(yùn)動(dòng)的多樣性、生長(zhǎng)發(fā)育多樣性、細(xì)胞結(jié)構(gòu)多樣性、細(xì)胞化學(xué)多樣性、代謝功能多樣性、遺傳變異多樣性等。所以它是有著*利用價(jià)值的生物資源。這一資源不僅表現(xiàn)為與人類生存著動(dòng)息息相關(guān)的幾乎所有生物無窮的代謝功能性狀，也同樣表現(xiàn)為一個(gè)五彩繽紛的微生物世界。① 核質(zhì)與細(xì)胞質(zhì)之間無核膜因而無成形的細(xì)胞核（擬核或類核）；RNA轉(zhuǎn)錄和翻譯同時(shí)進(jìn)行。
② 遺傳物質(zhì)是一條不與組蛋白結(jié)合的環(huán)狀雙螺旋脫氧核糖核酸（DNA）絲，不構(gòu)成染色體（有的原核生物在其主基因組外還有更小的能進(jìn)出細(xì)胞的質(zhì)粒DNA）；
③ 以簡(jiǎn)單二分裂方式繁殖，無有絲分裂或減數(shù)分裂；
④ 沒有性行為，有的種類有時(shí)有通過接合、轉(zhuǎn)化或轉(zhuǎn)導(dǎo)，將部分基因組從一個(gè)細(xì)胞傳遞到另一個(gè)細(xì)胞的準(zhǔn)性行為（見細(xì)菌接合）；
⑤ 沒有由肌球、肌動(dòng)蛋白構(gòu)成的微纖維系統(tǒng)，故細(xì)胞質(zhì)不能流動(dòng)，也沒有形成偽足、吞噬作用等現(xiàn)象；
⑥ 鞭毛并非由微管構(gòu)成，更無“9+2”的結(jié)構(gòu)，僅由幾條螺旋或平行的蛋白質(zhì)絲構(gòu)成；
⑦ 細(xì)胞質(zhì)內(nèi)僅有核糖體而沒有線粒體、高爾基體、內(nèi)質(zhì)網(wǎng)、溶酶體、液泡和質(zhì)體（植物）、中心粒(低等植物和動(dòng)物)等細(xì)胞器；⑧ 細(xì)胞內(nèi)的單位膜系統(tǒng)除藍(lán)細(xì)菌另有類囊體外一般都由細(xì)胞膜內(nèi)褶而成，其中有氧化磷酸化的電子傳遞鏈（藍(lán)細(xì)菌在類囊體內(nèi)進(jìn)行光合作用，其他光合細(xì)菌在細(xì)胞膜內(nèi)褶的膜系統(tǒng)上進(jìn)行光合作用；化能營(yíng)養(yǎng)細(xì)菌則在細(xì)胞膜系統(tǒng)上進(jìn)行能量代謝）；
⑨ 在蛋白質(zhì)合成過程中起重要作用的核糖體散在于細(xì)胞質(zhì)內(nèi)，核糖體的沉降系數(shù)為70S；
⑩ 大部分原核生物有成分和結(jié)構(gòu)*的細(xì)胞壁等等。總之原核生物的細(xì)胞結(jié)構(gòu)要比真核生物的細(xì)胞結(jié)構(gòu)簡(jiǎn)單得多。
原核生物細(xì)胞能進(jìn)行有氧呼吸。有的原核生物，如硝化細(xì)菌、根瘤菌，雖然沒有線粒體，但卻含有全套的與有氧呼吸有關(guān)的酶，這些酶分布在細(xì)胞質(zhì)基質(zhì)和細(xì)胞膜上，因此，這些細(xì)胞是可以進(jìn)行有氧呼吸的。利用細(xì)胞膜和細(xì)胞質(zhì)的酶系進(jìn)行有氧呼吸。*個(gè)階段發(fā)生的場(chǎng)所在細(xì)胞質(zhì)內(nèi)，產(chǎn)生的丙酮酸進(jìn)入三羧酸循環(huán)，被*氧化生成CO2和水，同時(shí)釋放大量能量.因其呼吸鏈組分在細(xì)胞膜上，所以主要在細(xì)胞膜上進(jìn)行。有的原核生物如產(chǎn)甲烷桿菌等，沒有與有氧呼吸有關(guān)的酶，因此，只能進(jìn)行無氧呼吸。總之，大多數(shù)原核生物能進(jìn)行有氧呼吸。

Such as the diversity of cell morphology, exercise diversity, growth and development diversity, cell structure diversity, cytochemical diversity, metabolic diversity, genetic diversity and diversity. So it is a biological resource with extremely high utilization value. This resource shows not only the infiniy metabolic metabolic traits of almost all living things closely related to human existence, but also a colorful world of microorganisms. ① nuclear and cytoplasm between nuclear-free membrane and therefore no shape of the nucleus (mimic or nucleoid); RNA transcription and translation at the same time.
② The genetic material is a circular double helix deoxyribonucleic acid (DNA) filament that does not bind histone, and does not form a chromosome (some prokaryotes have smaller plasmid DNA that can enter and leave the cell outside of their host genome);
③ simple two-division breeding, no mitosis or meiosis;
④ There is no sexual activity, and some species sometimes have the quasi-act of transferring parts of the genome from one cell to another through conjugation, transformation or transduction (see bacterial conjugation);
⑤ no myofibers, actin composed of microfibrillar system, so the cytoplasm can not flow, nor the formation of pseudo-foot, phagocytosis and other phenomena;
⑥ flagella is not composed of microtubules, but no "9 +2" structure, composed of only a few spiral or parallel protein filaments;
⑦ only the cytoplasm of the ribosome without mitochondria, Golgi apparatus, endoplasmic reticulum, lysosomes, vacuoles and plastids (plants), centrioles (lower plants and animals) and other organelles; ⑧ cells in addition to the unit membrane system Cyanobacteria usually belong to extracellular thylakoid folds formed by the cell membrane, including oxidative phosphorylation of the electron transport chain (cyanobacteria in the thylakoid photosynthesis, other photosynthetic bacteria in the cell membrane pleat membrane system photosynthesis ; Chemical and nutrient bacteria in the cell membrane system for energy metabolism);
⑨ in the process of protein synthesis plays an important role in the scattered ribosomes in the cytoplasm, the sedimentation coefficient of ribose 70S;
⑩ most of the prokaryotes have unique composition and structure of the cell wall and so on. In conclusion prokaryotes have a much simpler cell structure than eukaryotes.
Prokaryotic cells can breathe aerobically. Some prokaryotes, such as nitrifying bacteria and rhizobia, have no mitochondria, but contain a complete set of enzymes related to aerobic respiration. These enzymes are distributed on the cytoplasm and the cell membrane. Therefore, these cells are capable of aerobic respiration . Use of cell membranes and cytoplasmic enzymes for aerobic respiration. The first stage takes place in the cytoplasm where the pyruvate produced enters the tricarboxylic acid cycle and is thoroughly oxidized to produce CO2 and water, releasing a large amount of energy at the same time as the respiratory chain component is on the cell membrane and is therefore mainly on the cell membrane . Some prokaryotes such as methanogens, etc., no aerobic respiration-related enzymes, therefore, only anaerobic respiration. In conclusion, most prokaryotes are aerobic respirators.
