Prokaryotic And Eukaryotic Analysis
“Cells are the basic building blocks of all living things” (Genetics Home Reference, 2015), cells are the smallest unit that is capable of performing life functions. They are responsible for the conversion of nutrients from food into energy, the structure of the body and perform specialised functions for each different organelle.
There are two main types of cells, Prokaryotic and Eukaryotic. The Prokaryotic (see appendix one) is a single-celled organism without a membrane-bound structure, meaning it lacks a nucleus, mitochondria and any other membrane-bound organelles (Unknown, 2015).

The Eukaryotic is any cell or organism that has a cell membrane-bound structure. Meaning it contains the major organelles inside a cell (Arrington, 2014).

The Original model of the structure of a membrane was created by Davson and Danielli, where there unit membrane was covered by a liquid bilayer coated with protein. An example of this protein is the Aquaporins; these are the water transporting channels of the membrane using the passive process (Tajkhorshid, 2006). This model has been modified due to many years of research and the accepted model of the structure is the “Fluid-Mosaic Model” to view this diagram of the model head to image three of the …show more content…
As the potato has a semi-permeable membrane will allow the diffusion of water molecules to go in and out of the potato, depending on the concentration gradient between the potato and the solutions. If the solutions have a higher concentration of carbohydrates or glucose, then the potato the water will pass through the membrane and into the potato and it will gain weight. However, if the solution has a lower concentration then the potato the water will go out of the potato through the membrane and into the solution as osmosis is the movement of water molecules from a high concentration gradient to a lower concentration. But, there is a chance that the solution has the same concentration gradient as the potato meaning that the water will freely move back and forth from each substance without the change of

    The word cell comes from the Latin word “cellula”, which means a small room. The cell is the smallest unit of a living organism, also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms), and multicellular organisms. There are different types of cells, prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining; it takes in nutrients, converts them into energy, carries out special functions and reproduces itself if necessary.” The descriptive name for the smallest living biological structure was given by Robert Hooke in a book, which he published in 1665, while discovering “small units” in a cork. After that the research of the cell has progressed greatly.…

    In the 1800s, the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell, the object in question must be able to reproduce, respond to chemical signals, obtain energy, maintain homeostasis, and undergo evolution. All cells can be divided into two different categories: prokaryotes or eukaryotes. Bacteria and archaea are classified as prokaryotes while animals and plants are eukaryotes. Prokaryotes are small and unicellular. Due to their small size, they do not have…

    But not all cells are alike. Cells come in many shapes and sizes and perform various functions, depending on where they are found (Infographic 3.2). Moreover, they fall into two fundamentally different categories: prokaryotic or eukaryotic. Prokaryotic cells are relatively small and lack internal membrane-bound compartments, called organelles. Eukaryotic cells, by contrast, are much larger and contain many such organelles.…

    A chromosome is necessary so that there is a “map” of the cells function and structure, cytoplasm is necessary as it is where most of the cell’s activity occurs, ribosomes are essential as they are the site of protein synthesis, which powers the activities of the cells, and the cell membrane is needed to give the cell structure and protection. Most cells have other structures based upon their function, and these extra structures are necessary in order for that cell to perform it’s function.…
