Cellular Life: Prokaryotes and Eukaryotes

Cellular Life: Prokaryotes and Eukaryotes

Cellular life is made up of two forms of life it includes the prokaryotes and Eukaryotes evolved from prokaryotes. The process through which the evolution occurred can be attributed to various biochemical theories. The process was, however, not transparent as outlined initially. However, with time the process became more understood with the advent of ribosomal rRNA. The process was further attributed to molecular-based methods that later led to the formation of Bacteria and Archaea through a three-domain process. The distinction between each of them was defined through the phylogenetic representation of the duplicated genes.

The eukaryotic cells exist in structurally advanced form. The process is explained through basic biological concepts that describe the evolution and advancement of simple organisms. Also, endosymbiosis plays a significant role in the understanding eukaryotes. The process outlines its structures and the activities it conducts and the nature of exercises it performs in the body. Based on their structures, the eukaryotes, have more specialized organelles that function independently. It is unlike the case of prokaryotes that carry out simple activities and have a minimal task to achieve. The eukaryotes have an n advanced system that coordinated one different operation through enclosed organelles. Therefore, it provides a different variance when co oared in terms of functionality and structure

The evolution of the eukaryotic levels has long been linked to simplicity endomemabranes and cytoskeletons. They are thought to have occurred in form from simple membranous molecules. The process of formation was then perceived to occur as a result of polymerization of the molecules that then existed in a primitive environment. Thus arose from a simple nucleus to membranous cells that later  gave rise  to the complex cells

The prokaryotes include major forms of the simple organism. For example, Bacteria is classified into different groups. They have further been ranked based on the type of environment that the microorganisms exist. For instance, thermophiles and eubacteria are most common in the selected environment. Most of the bacteria cell is spherical and rod-shaped. The DNA content is also simple and contains different types of proteins. Besides, the bacterial is further grouped in the kind of food and the environment. They include cell wall which is surrounded by peptides and different forms of polysaccharides. Plasma membranes are also common that provides a functional role and conducts vital activities between the internal and external parts of the prokaryotic cell.  Its DNA is one of the most critical components as compared to other parts of the cell. It is made up of a circular molecule that is contained in the nucleoid. Besides its cytoplasm region contains vital components such as ribosome which play a major role in the processing of proteins. The ribosome also contributes to the granular like of the cells when viewed under the microscope.

On the other hand, the eukaryotic cells are surrounded by the plasma membrane and contain other organelles at its cytoplasm. As compared to prokaryotic cells, the eukaryotes are more complex than the prokaryotes. Besides, its nucleus is more complicated compared to other parts of the cellular organelles. It is enclosed within the cytoplasm. Therefore its organelles are separated into different parts, and this is achieved through membranous surrounding the organelles.  Other include the endoplasmic reticulum which plays a vital role in extending the nucleus and functions as the critical organ in the production of lipids. Vesicles act as the core transported of proteins that are densely distributed in the cytoplasm. On the other hand, the Golgi apparatus carries such substances to their final destinations

Unlike the prokaryotic cells, the eukaryotes are organized into cytoskeletons. The cytoskeleton is a structure that functions to provide shape to the cell structures. The structure also facilitates the movement of structures Therefore the evolution of the eukaryotic cell’s can be viewed as the process where the organelles were enclosed through the membranes Besides its symbiotic association is supported by structures such as chloroplast and. They have a significant likelihood of the evolution. The chloroplast is divided into a different compartment that helps the process of photosynthesis. Besides the mitochondria plays a vital role in supplying the required energy for cellular acclivities. The lysosome and peroxisome play an essential role in metabolism.

Endosymbiosis is one of the vital processes that explain how the two types of cells contributed to the growth and evolution of advanced cellular life.  The origin of the organisms is attributed to a combination of two beings. Algae is an example of the microorganisms that demonstrate the occurrence of the process

The membranous organelles involve those enclosed by the membranes, and this are mostly found among the Eukaryotes The organelles include the nucleus, ribosome, mitochondria vesicle and other vital components such as lysosome. The membranous context is attributed to major endosymbiotic process and other concepts of endogenesis. When explained based on the contemporary context of prokaryotes and eukaryotes, it is evident that the bacteria have simple structures with open organelles. Besides, their structure is simple and this attributes to many factors and characteristics such as those that cause diseases and ability to survive in any environment They can easily adapt to a harsh environment. Their reproduction is also simple, and this is further evidence from the way it spreads from one are to the other.

Some of the structures that the cells have in common are the cell membrane. They have similar consistency throughout the cells. They contain phospholipids and other molecules the facilitates consistency This includes the proteins and carbohydrates  Phospholipids are held in both sides of the membranes They define the function of both internal and external components of the cells. On the other hand, the proteins and cholesterol strengthen the membrane by reducing the ability of different molecules from crossing the layer. Therefore it ensures that the cells are protected and provides the essential medium for cellular activities. To achieve this, the cell allows some compounds inside the cells and hinders others from getting to the cell It, therefore, provides an opportunity for the cell to selectively exchange cellular materials with the aim of achieving a regulated medium for the substance of the cellular activities.

The membranous organelles include all the enclosed organelles found in the cells. On the contrary, unenclosed include the cytoplasm and some part between the cell membranes. Cytoplasm acts as the site of different cellular activities. It, therefore, regulates different biological processes and provides an opportunity for appropriate regulation of substances and maintenance of the cellular pH. The membranous organelles, however, have independent regulations process which is achieved through the aid of the enzymes. While those with membranes have specialized roles, non-membranous conduct general activities aimed at providing support to the significant parts of the cells.
