What are the characteristics of prokaryotic cells?
Prokaryotic mobileular is a unicellular organism missing membrane-sure organelles. The traits of prokaryotic cells are as follows: (i) Most of them are unicellular. (ii) They are commonly small in length. The length of a prokaryotic mobileular varies from 0.five - five µm. (iii) The nuclear place of a prokaryotic mobileular is poorly-described due to the absence of a nuclear membrane. Hence, a prokaryotic mobileular lacks a real nucleus. (iv) The genetic substances of prokaryotic cells are naked. They include single, round chromosomes. In addition to the genomic DNA, they have got a small, round plasmid DNA.(v) They have specialized membranous systems referred to as mesosomes. Mesosomes are fashioned via way of means of the invagination of the mobileular membrane. These extensions assist withinside the synthesis of the mobileular wall, replication of DNA. They additionally assist withinside the same distribution of chromosomes into the daughter cells. (vi) Membrane-sure mobileular organelles along with mitochondria, plastids, and endoplasmic reticulum are absent from a prokaryotic mobileular. (vii) Most prokaryotic cells comprise a three-layered shape - outermost glycocalyx, center mobileular wall, and the innermost plasma membrane. This shape acts as a defensive unit. Examples of prokaryotic cells consist of blue inexperienced algae, bacteria, etc.
