Compare And Contrast Eukaryotic And Bacterial Cells

You can identify a eukaryotic cell by its encased nucleus, containing the majority of its DNA and organelles surrounded by a membrane. Plant and Animal cells have double membranes and a housed nucleus therefore they are eukaryotic cells; organisms which do not contain a double membrane and an encased nucleus are known as prokaryotes, e.g. bacteria. The eukaryotic cell is made up of many membrane bound organelles which all have a specific function.

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

“Eukaryotic cells are complex and include all animal and plant cells. Prokaryotic cells are smaller and simpler, e.g. Bacteria” - (AQA 2008)

Now that we understand the properties of life and the composition of cells, we can focus on the architecture or formation in terms of basic anatomy and physiology as our second area of exploration. The two types of cells (prokaryotic and eukaryotic) defined before have a few common things such as Plasma membrane (similar to animal cells); Cell wall (similar to plant cells); and Ribosomes, the

On the planet, Earth, prokaryotic and eukaryotic are the two major types of cells. Prokaryotic cells are defined as cells with genetic material and cell chemicals all enclosed within a cell wall, and having no defined organelles or nucleus (except ribosomes). Organisms in this group are small in size and mainly consist of bacteria. Eukaryotic cells, however, are defined as having a ‘’true’’ nucleus, membrane-bound organelles, and chromosomes. The nucleus of eukaryotic cells houses the deoxyribonucleic acid (DNA) and directs the synthesis of proteins and ribosomes. Prokaryotic cells, however, are much older cells as these cells are quite ancient and were the only form on planet Earth for billions of years, soon giving birth to eukaryotic cells 1.5 billion years ago.

The bacteria cell looks like a pill capsule with a long tail called a flagella. Attached to the outside of the capsule like cell are spaghetti like pili. Around the cell is a cell wall. The cell wall, capsule cytoplasmic membrane are all like a wall around the cell. The Ribosomes are like a bunch of tiny little dots within the cell wall. In the middle of the cell is the nucleoid. The cytoplasm is a jell like structure contain of the cells interior parts. The nucleoid is scattered strands of DNA. I looks a lot like pieces of hair woven

Cells are the basic components of all living things. Both the prokaryotic and the eukaryotic cell contain a plasma membrane, a cytoplasm, DNA, and ribosomes. One of the main differences between a eukaryotic and prokaryotic cell is that a prokaryotic cell lacks a nucleus, (pro means before and kary means nucleus) and it also lacks membrane-bound organelles. Instead of having a nucleus, prokaryotes have a single chromosome. This chromosome is often referred to as a gonophore. Due to prokaryotes being single celled, the inside of a prokaryotic cell is full of open space, meaning they do not contain any membrane walls. The prokaryotic cell makes up all bacteria and bacteria-like archaea (germs).

In the comparison image between prokaryotic and eukaryotic cells it highlights the specialised structures of both cell types, the specialised cell structures allow cells to perform certain functions needed in the organisms it contains. Prokaryotic cells contain flagella which eukaryotic cells do not and eukaryotic cells have many important structures such as the nucleus or information processing centre of the cell.

Bacteria cells are somewhat different from plant or animal cells. A bacteria cell has no nucleus are membrane-bound organelles. Unlike animal or plant cells have pill flagella and a cell capsule. The cell membrane on the bacterial holds protein, nutrients, and other important components inside the cell. The cell membrane of a bacteria cell has many different names. It 's be called plasma, lipid membrane or cytoplasm.

Cells are the basic unit of all living things. The two most important types of cells are prokaryotic and eukaryotic cells. These two types of cells differ in many ways, but they also share similarities. One thing prokaryotic and eukaryotic cells have in common is that they both contain a plasma membrane and cytoplasm. Another similarity between prokaryotic and eukaryotic cells is that they contain ribosomes.

In effort to show that I know the topic of the lab that I missed, I must write a 1200-word paper on bacterial diversity. To write a paper on bacterial diversity I must define what bacterial diversity is, according to the lab manual “prokaryotic, unicellular organisms are represented by two biological kingdoms: archaebacterial and eubacteria. Their cells are typically quite small, and lack complex, membrane bound organelles. The few non membrane bound organelles that prokaryotic cells do have are different in size and /or structure than those of eukaryotic cells” (2017) in addition to the lab manual classification of bacterial cells comes down to the bacterial cells colonies. According to our text book (essentials of the living

The difference between prokaryote and eukaryote is shown in the table below: Prokaryote cell Eukaryote cell Prokaryote are always unicellular (single cell) organisms Eukaryote are usually multicellular (contains multiple cell) Prokaryotic cell has no cytoskeleton Eukaryotic cell always have cytoskeleton Prokaryote cell are without nucleus Eukaryote contains nucleus Prokaryote are smaller in size Eukaryote are larger in size Prokaryote cell are found in Bacteria and Archaea Eukaryote are found in plants and animals Endoplasmic reticulum and mitochondria are not present in prokaryote cell Endoplasmic reticulum and mitochondria are present in eukaryote cell Golgi apparatus and lysosome are not present Golgi apparatus and lysosome are present Reproduction

There are three main types of bacteria.They can be determined and distinguished by their cell morphology. Cell morphology is the identification of the shape, structure, size of the cell and its form. It pertains to the shape of bacteria. For instance, Coccus (cocci) bacterium are spherical and generally round shaped. Bacillus bacterium are generally rod shaped and are a genus of gram positive bacteria. Finally, the third common type of bacterial morphology is the spirillum bacteria. Spirillum bacteria s generally a spiral shaped bacterium and are a genus of the Gram

The capsule is a protective covering around the bacterial cell, on the very outside of the cell- the role of the capsule is to keep the bacterium from drying out and protect it from larger organisms, some bacteria that cause major diseases will not infect with the disease if it is a nonencapsulated mutant (a bacterial cell without the capsule). It also includes the cell envelope, cell wall, cytoplasm, cytoplasmic membrane, flagella, nucleoid, pili and ribosomes. The flagella supports swimming movement and is composed of proteins, the ribosomes are the site of translation and protein synthesis, composed of RNA and proteins.

The structure of cholera is that of a prokaryote cell. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus or any membrane-bound organelles. Instead they have a single chromosome, double stranded piece of deoxyribonucleic acid (DNA) which is located in the nucleoid. There is also ribosomes and plasmids in prokaryotic cells. There is a cell wall outside of the plasma membrane, this dictates the shape of the cell and acts as a protective layer for the cell, defending it from our bodies natural immune response. Cholera takes the shape of a pentagon. Some prokaryotic cells have flagellum to enable the cell to move however, cholera does not have flagellum. The structure of cholera differs to that from a eukaryotic cells in many ways.
