比如細胞形態(tài)的多樣性、運動的多樣性、生長發(fā)育多樣性、細胞結(jié)構(gòu)多樣性、細胞化學(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*利用價值的生物資源。這一資源不僅表現(xiàn)為與人類生存著動息息相關(guān)的幾乎所有生物無窮的代謝功能性狀，也同樣表現(xiàn)為一個五彩繽紛的微生物世界。① 核質(zhì)與細胞質(zhì)之間無核膜因而無成形的細胞核（擬核或類核）；RNA轉(zhuǎn)錄和翻譯同時進行。
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出細胞的質(zhì)粒DNA）；
③ 以簡單二分裂方式繁殖，無有絲分裂或減數(shù)分裂；
④ 沒有性行為，有的種類有時有通過接合、轉(zhuǎn)化或轉(zhuǎn)導(dǎo)，將部分基因組從一個細胞傳遞到另一個細胞的準性行為（見細菌接合）；
⑤ 沒有由肌球、肌動蛋白構(gòu)成的微纖維系統(tǒng)，故細胞質(zhì)不能流動，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(低等植物和動物)等細胞器；⑧ 細胞內(nèi)的單位膜系統(tǒng)除藍細菌另有類囊體外一般都由細胞膜內(nèi)褶而成，其中有氧化磷酸化的電子傳遞鏈（藍細菌在類囊體內(nèi)進行光合作用，其他光合細菌在細胞膜內(nèi)褶的膜系統(tǒng)上進行光合作用；化能營養(yǎng)細菌則在細胞膜系統(tǒng)上進行能量代謝）；
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)*的細胞壁等等。總之原核生物的細胞結(jié)構(gòu)要比真核生物的細胞結(jié)構(gòu)簡單得多。
原核生物細胞能進行有氧呼吸。有的原核生物，如硝化細菌、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，這些酶分布在細胞質(zhì)基質(zhì)和細胞膜上，因此，這些細胞是可以進行有氧呼吸的。利用細胞膜和細胞質(zhì)的酶系進行有氧呼吸。*個階段發(fā)生的場所在細胞質(zhì)內(nèi)，產(chǎn)生的丙酮酸進入三羧酸循環(huán)，被*氧化生成CO2和水，同時釋放大量能量.因其呼吸鏈組分在細胞膜上，所以主要在細胞膜上進行。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，只能進行無氧呼吸。總之，大多數(shù)原核生物能進行有氧呼吸。

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.
