They need energy to survive, contain cytoplasm inside the cells and a cytoskeleton.
Prokaryotes and eukaryotes are two types of organisms. Bacteria and Archaea are prokaryotes. Prokaryotes have a simple cellular organization. They do not have a nucleus and true organelles. On the other hand, eukaryotes have a complex cellular organization with a membrane-bound nucleus and true organelles. Fungi, protists, plants, and animals are eukaryotes. Overview and Key Difference 2. What is Genetic Material of Prokaryotes 3. What is Genetic Material of Eukaryotes 4. Prokaryotes are the organisms that do not have a nucleus. They are single-celled. Hence they have a simple cell organization. The genetic material of prokaryotes floats in the cytoplasm.
Bacteria have a large circular chromosome which is highly coiled. They also possess extra-chromosomal DNA known as plasmids. Plasmids are not necessary for their day to day survival. But they contain important genes such as antibiotic-resistant genes, pesticide resistance genes, etc. In addition, these DNA molecules are small in size and are able to self-replicate. Due to these properties, they serve as very valuable vectors in recombinant DNA technology and cloning. Eukaryotes are organisms that possess a nucleus and true organelles in their cells. Their genetic material is located inside the membrane-bound nucleus. The eukaryotic genetic material is linear and wrapped around proteins called histones. It contains many sequences which are non-coding.
Moreover, eukaryotic genes do not transcribe together. They transcribe separately and make their own mRNA molecules. One promoter regulates the transcription of one gene in eukaryotes. In contrast, prokaryotes — bacteria and archaea — are single-celled organisms, with only a few exceptions. Prokaryotes tend to have smaller cell sizes than eukaryotes. The reason for the difference in cell sizes between prokaryotic cells and eukaryotic cells belongs to the different structure and organization between the two types of cells.
The lack of membrane-bound organelles in prokaryotes might be the most noticeable difference. While eukaryotic cells contain organelles enclosed in membranes — two examples would be the Golgi body and the endoplasmic reticulum — prokaryotes do not. Prokaryotes also lack a membrane-bound nucleus, which is another organelle. Without a nucleus or any other organelles, prokaryotic cells are incapable of the kinds of specialized functions that eukaryotic cells engage in. Eukaryotes store their DNA as chromosomes within the nucleus, but prokaryotes lack the nucleus. Instead, most of their DNA is in one chromosome-like structure that sits in an area of the cytoplasm called the nucleoid. This nucleoid does not have a membrane of its own. Additional bits of DNA called plasmids are shaped like rings and exist in the cytoplasm outside the nucleoid.
Prokaryotic cells engage in reproduction through a process of cell division called binary fission. Eukaryotic cells use a different process of cell division called mitosis , which involves a constant cycle of cell growth and development. A fundamental part of all life on Earth is the transfer of genetic material to future generations. Eukaryotes reproduce sexually through a process called meiosis , which randomly sorts the genes from two parents to form the DNA of the offspring. Sexual reproduction maximizes the genetic variability of the offspring of two parents, strengthening the genetic line and minimizing the risk of a random mutation wiping out most of a population.
Prokaryotes reproduce asexually, which creates a precise copy of the original cell. Genetic variance comes in the form of less complex processes of gene transfer than eukaryotes, such as transduction. In this process, genes are transferred from one bacterial cell to another by means of viral cells. The viruses grab the plasmids from one bacterium and transfer it to another bacterial cell.
For all the differences between prokaryotic cells and eukaryotic cells, they have some features in common, too. Both cells have a plasma membrane, which serves as a barrier between the inside of the cell and the outside. The plasma membrane uses certain molecules embedded within it to allow foreign bodies to pass into the cell or to allow matter within the cell to pass out of the cell.
Proteins embedded in the membrane do something similar, as well: they act as pumps that push matter into or out of the cell, rather than allowing it to pass through. Both prokaryotes and eukaryotes have ribosomes. Ribosomes are small organelles used to synthesize proteins as the cell needs them. They can either float freely in the cell or sit on the surface of the rough endoplasmic reticulum in eukaryotic cells, giving it the designation of "rough," in comparison to its smooth sibling that lacks ribosomes.
They receive messages from messenger RNA molecules , telling them what proteins the cell needs. They translate these messages into protein molecules by assembling amino acids. Although the process of protein synthesis works differently in prokaryotes and eukaryotes, it is is closely related and involves ribosomes in both cases. Rebecca E.
