FREE The Differences Between Prokaryotic and Eukaryotic Cells Essay

prokaryote and eukaryote similarities

Eukaryotic cells are larger than prokaryotic cells. But eukaryotic cells consist of a true nucleus enclosed by two membranes. Moreover, it does not contain spaces between genes. Eukaryotic cytoskeleton is composed of microfilaments, microtubules and intermediate filaments. This is one difference between prokaryotic and eukaryotic genome. Eukaryotic Cells In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells.

Difference Between Prokaryotic and Eukaryotic mRNA

prokaryote and eukaryote similarities

The key difference between prokaryotic and eukaryotic genome is that the prokaryotic genome is present in the while eukaryotic genome confines within the. Pro … karyotic cells have no nucleus. Prokaryotic cells are quite simple in structure. Eukaryotes can be single-celled or multi-celled organisms they are usually multi-celled , so they have a lot more components. Most prokaryotes are made up of just a single cell unicellular but there are a few that are made of collections of cells multicellular. Replication also happens at a much faster rate in prokaryotic cells, than in eukaryotes. They have extensive cellular compartments that carry out distinct functions.

What Are the Main Differences Between Prokaryotes and Eukaryotes?

prokaryote and eukaryote similarities

With comparison to the prokaryotic genome, the eukaryotic genome is bigger and has billions of base pairs. Some cellular processes arose from the need of the organism to defend itself. Plant cells contain chloroplasts for the photosynthesis. Some eukaryotes do have flagella for example sperm , but they do not have pili. If the cell could quickly shut off gene expression for a short period of time, it would be able to survive an infection when other organisms could not.

However the more general dif … ference is that eukaryotic cellscontain organelles e. Since prokaryotes consist of great diversity, they obtain energy from inorganic compounds like hydrogen sulfide in addition to the photosynthesis and organic compounds. Other differences Prokaryotes do not have an endoplasmic reticulum, a Golgi apparatus, lysosomes, or peroxisomes; but eukaryotes do. It is derived from a Greek word meaning before nuclei. The usually pattern is to find and exploit resources as quickly as possible and then replicate. Prokaryotic cells and Eukaryotic cells both can contain a cell wall however in prokaryotic cells the cell wall is peptidoglycan a mixture of sugar and protein if the organism is a eubacteria, or pseudomurein if the organism is a archae bacteria whereas in eukarotic cells a cell wall is only present if the organism is a plant or a fungi and the cell wall is constructed of cellulose in plants or chitin if the organism is a fungi. Chemical composition of transcript is similar in both groups 4.

Examples of organelles would be a nucleus, chloroplasts, or mitochondria. Eukaryotic Cell: Some cells without cell wall contain flagella. Eukaryotic Cell: Eukaryotic cells consist of multiple, linear chromosomes in the nucleus. Proteins of both prokaryotes and eukaryotes contain the same general motifs: alpha helics, beta sheets and so on. They have similar basic metabolism. Figure 01: Prokaryotic Cell and Genome Due to their small sizes, prokaryotic genome mainly contains coding sequences exons. Plasma Membrane Prokaryotic Cell:Carbohydrates and sterols are not found in the plasma membrane.

Prokaryotic DNA vs Eukaryotic DNA

prokaryote and eukaryote similarities

Within the nucleus of eukaryotes, we can find the eukaryotic genome that contains the whole genetic information of the organism. The larger the cell size means that more cell processes are going on. Prokaryotic cells possess one or two types of polymerases, whereas eukaryotes have four or more. Eukaryotic cells are composed of a variety of membrane-bound organelles. Four types of shapes can be identified in bacteria: spherical-shaped cocci , rod-shaped bacilli , spiral-shaped spirochaete and comma-shaped vibrio. All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells: the and the eukaryotes.

When eukaryotes reproduce sexually, they use a process called meiosis. An 80S ribosome is composed of a 40S subunit and a 60S subunit while a 70S ribosome consists of a 30S subunit and a 50S subunit. However, prokaryotes differ from eukaryotic cells in several ways. These organisms are divided into two groups depending on the components of the cell wall: Bacteria and Archaea. Bacteria consist of a single circular chromosome.

Ribosomes in both the cell carry out same function. The basic unit of life is cell. Structurally, prokaryotic genome is more compact than eukaryotic genome. These differences are key to how they function and which jobs they are suitable to perform. Similarly, any wastes produced within a prokaryotic cell can quickly move out.
