比如细胞形态的多样性、运动的多样性、生长发育多样性、细胞结构多样性、细胞化学多样性、代谢功能多样性、遗传变异多样性等。所以它是有着*利用价值的生物资源。这一资源不仅表现为与人类生存着动息息相关的几乎所有生物无穷的代谢功能性状，也同样表现为一个五彩缤纷的微生物世界。① 核质与细胞质之间无核膜因而无成形的细胞核（拟核或类核）；RNA转录和翻译同时进行。
② 遗传物质是一条不与组蛋白结合的环状双螺旋脱氧核糖核酸（DNA）丝，不构成染色体（有的原核生物在其主基因组外还有更小的能进出细胞的质粒DNA）；
③ 以简单二分裂方式繁殖，无有丝分裂或减数分裂；
④ 没有性行为，有的种类有时有通过接合、转化或转导，将部分基因组从一个细胞传递到另一个细胞的准性行为（见细菌接合）；
⑤ 没有由肌球、肌动蛋白构成的微纤维系统，故细胞质不能流动，也没有形成伪足、吞噬作用等现象；
⑥ 鞭毛并非由微管构成，更无“9+2”的结构，仅由几条螺旋或平行的蛋白质丝构成；
⑦ 细胞质内仅有核糖体而没有线粒体、高尔基体、内质网、溶酶体、液泡和质体（植物）、中心粒(低等植物和动物)等细胞器；⑧ 细胞内的单位膜系统除蓝细菌另有类囊体外一般都由细胞膜内褶而成，其中有氧化磷酸化的电子传递链（蓝细菌在类囊体内进行光合作用，其他光合细菌在细胞膜内褶的膜系统上进行光合作用；化能营养细菌则在细胞膜系统上进行能量代谢）；
⑨ 在蛋白质合成过程中起重要作用的核糖体散在于细胞质内，核糖体的沉降系数为70S；
⑩ 大部分原核生物有成分和结构*的细胞壁等等。总之原核生物的细胞结构要比真核生物的细胞结构简单得多。
原核生物细胞能进行有氧呼吸。有的原核生物，如硝化细菌、根瘤菌，虽然没有线粒体，但却含有全套的与有氧呼吸有关的酶，这些酶分布在细胞质基质和细胞膜上，因此，这些细胞是可以进行有氧呼吸的。利用细胞膜和细胞质的酶系进行有氧呼吸。*个阶段发生的场所在细胞质内，产生的丙酮酸进入三羧酸循环，被*氧化生成CO2和水，同时释放大量能量.因其呼吸链组分在细胞膜上，所以主要在细胞膜上进行。有的原核生物如产甲烷杆菌等，没有与有氧呼吸有关的酶，因此，只能进行无氧呼吸。总之，大多数原核生物能进行有氧呼吸。

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.
