    Gene expression is the ability of a gene to produce a biologically active protein. This process is regulated by the cells of an organism, it is very important to the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity

    Eukaryotic Cells The cell may be regarded as the basic unit of an organism, it carries out the essential processes that make the organism a living entity. All cells share certain structural and functional features and they are of almost universal occurrence in living organisms. Biologists have devoted a great deal of attention to its structure and the processes that go on inside it. They have recognised a major distinction between two types of cells, Eukaryotic cells that have a nucleus

    Introduction In this lab, we observed different prokaryotic and eukaryotic cells, and then we observed a termite gut to see the different unicellular microorganisms that it contained. The purpose of this lab is to observe living and prepared bacterial cells, then describe their morphology, observe and describe the primary features of the eukaryotic cell, and to investigate and observe the organisms involved in a symbiotic relationship. By observing these things, we are hoping to find out what we

    Part A Prokaryotic and Eukaryotic Cells Introduction Prokaryotic and Eukaryotic cells are both found in living thing, they have similarities and differences. This will be discussed further on in the essay. Prokaryotic cells are found in organism like bacteria which are archaebacterial and eubacteria whereas, eukaryotic cell are found in animals and plants. Prokaryotic cells Bacteria are prokaryotes, opposing from eukaryotes in having no membrane-bound nucleus or double- membrane organelles. Bacteria

    Eukaryotic cells are the most structurally advanced of the major cell types. Describe the structure and function of each of the eukaryotic organelles. Distinguish between those that are and are not membranous. Most are membranous. Eukaryotic cells, whether from animals, plants, protists, or fungi, are the most structurally advanced of the major cell types. Eukaryote are single-celled or multicellular organism whose cells contain nucleus and any other structures (organelles) enclosed within the

    A Comparison of Eukaryotic and Prokaryotic Cells There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life. Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually

    All cells are the product of multiple rounds of cell growth and division, new cells are formed from existing cells, as has been the processes since the beginning of life on Earth. The reproduction of new cells is a very organized sequence of events called the cell cycle. This cycle is the essential mechanism by which all living cells reproduce whether unicellalur or mutlicelluar the basic mechanism is universal. However, variations in the details do occur from organism to organism and the cycle can

    The plasma membrane of eukaryotic cells performs a multitude of tasks ranging from cell signaling to transport of ions and other molecules from the extracellular matrix into the cytosol. The membrane is the result of lipid packing into a bi-layer. The plasma membrane is composed of two sections, an outer section known as the exoplasmic layer, and an inner section known as the cytosolic layer. The two layers are composed of differing lipids with the exoplasmic layer containing primarily sphingolipids

    Eukaryotic Cell Structure Plant cells are unique among the eukaryotes (Greek for “true kernel”) (Origins. 2009) organisms whose cells have membrane-enclosed nuclei and organelles, because they can manufacture their own nutrients. Like the fungi, another kingdom of eukaryotes, plant cells have retained the protective cell wall structure of their prokaryotic ancestors. The basic plant cell shares a similar construction with the typical eukaryote cell, but does not have centrioles, lysosomes, intermediate

    prokaryotic and eukaryotic cells All the living beings are made up of cells. They contain nucleus, which controls and performs their activities. The cells are divided into the two main categories depending on whether they contain nucleus or not. They are: Prokaryotic cell Eukaryotic cell Simplest and ancient Complex and evolved from prokaryotes Single-cell Single - celled or multicellular Lacks nucleus Contains nucleus Contains cell wall (peptidoglycan)
