    are alive, and show the six characteristics of life. These cells are divided into two groups: eukaryotes and prokaryotes. Prokaryotes and eukaryotes might be similar, but they also have a lot of differences. First of all, eukaryotes and prokaryotes have the same basic structure. An example of this is the cytoplasm. Cytoplasm composes the volume or the inside of a cell. Cytoplasm is the place where eukaryotes’ nuclei are in place. Another example are cell walls. Cell walls provide support and help resist

    Gerald McDonnell 1. The major differences between prokaryotes and eukaryotes are as follows; prokaryotes are much smaller than eukaryotes, prokaryotes have a nucleoid instead of a nucleus (which eukaryotic cells have), prokaryotes lack a membrane bound organelles while eukaryotes have them, prokaryotes are bacterial cells while eukaryotes can be considered the building blocks of plant and animal life. 2. A. A nucleus is basically the “brain” of a cell. It controls reproduction and contains the genetic

    786 Words  | 4 Pages

    Introductory life sciences Assignment 1 Prokaryotes and eukaryotes are two different levels of cells. Prokaryotes are cells that do not have a membrane bound nucleus or organelles sounded by membranes and eukaryotes are cells that have a membrane bound nucleus as well as membrane bound organelle. They have obvious structural differences which result in differences functions and cell efficiency. From my research, I have observed that eukaryotes have structural advantages over prokaryotes. This essay

    differences between eukaryotes and prokaryotes that prove eukaryotes to be far more advanced than prokaryotes.The “focal point” for this assignment is on both types of cells and exploration of their structures proving why eukaryotes are more progressive than prokaryotes. The variance among the structures of prokaryotes and eukaryotes is considered to be the most important distinction between groups of organisms. The major difference between eukaryotes and prokaryotes is that eukaryotes have their DNA

  • Biochemistry: The Cytoskeleton

    These are formed by the polymerization of tubulins. Each tubulin molecule is a hetero dimer of two closely related and tightly associated subunits called α-tubulin and β-tubulin. Tubulins are highly conserved in all eukaryotes throughout the evolution. Each microtubule is typically composed of thirteen linear protofilaments of alternating α- and β-tubulins arranged in parallel to form a cylindrical structure. The microtubules are polar structure i.e. the beta-tubulin

    of archaea are unique among the three domains of life. Although archaea also possess a phospholipid bilayer, similar to bacteria and eukaryotes, the bilayer itself differs greatly in chemical composition. The first striking difference is the use of L-glycerol instead of D-glycerol, along with having an ether linkage linking the tail to the head; whereas eukaryotes and bacteria have an ester linkage. However the main difference in archaea membranes in the isoprenoid chain replacing the fatty acid

  • Meiotic Recombination Mechanism

    722 Words  | 3 Pages

    Mechanism of meiotic recombination The Meiotic recombination is an integral part of the meiotic division in most eukaryotes. It can lead to either crossovers (reciprocal exchange of genetic material between homologous chromosomes), or non-crossovers (non-reciprocal exchange of the genetic material). In eukaryotes, only a small percentage of meiotic DSBs result in crossover products (Sung et al., 2003; Youds and Boulton, 2011). In contrast, repair of DSBs in the mitotic cells happen mostly through

    Cytoskeletons are common for every living organisms present, be it bacteria, archaea, eukaryotes or prokaryotes. It is present in the cytoplasm of a cell and has a very complex network that consists of tubules and filaments that interlink each other1. Cytoskeletons are comprised of three main proteins in eukaryotes and they are usually able to multiply very fast or even disassemble depending on what the cell needs at any given moment.2 The structures of cytoskeletons can differ from one another and

  • Bacteria And Archaea Similarities

    992 Words  | 4 Pages

    The living organisms are classified into different groups by means of their differences and similarities. Two of the major/ most important groups are the prokaryotes (Bacteria and Archaea) and eukaryotes (from plants, animals till malaria parasites and fungi). The difference between them is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, whereas the prokaryotic cells don’t. There is also a difference in their cellular structure due to the lack of chloroplast, cell wall

  • Essay On Nucleolus

    2136 Words  | 9 Pages

    The core of the cell is the nucleus and the largest component of it is the nucleolus. The nucleolus is found in all the eukaryote cells and it is a non membrane bound nuclear organelle.[1] The nucleolus is a domain lacking membrane, which is high in proteins and RNA content. The proteins continually moves between the nucleolus and the nucleoplasm because of the dynamics within the cell. The structure of the nucleolus is divided into three main subcomportaments, which are the fibrillar center

  • Yeast Research Paper

    1065 Words  | 5 Pages

    YEAST Yeasts are eukaryotic unicellular fungi which reproduce by budding or fission. Yeasts are very small, typically 5 to 10 microns (1 micron = 10-4 centimeters) which is around 5 times the size of most bacteria. Yeast cell membranes acts as impermeable barriers against hydrophilic molecules to prevent the mixing of the cytoplasm and external environment. Around 7.5 n thick, the cell membrane is composed of a lipid bilayer (Walker, 1998). As with all eukaryotic membranes, the lipid bilayer

  • Cellular Membrane Essay

    1190 Words  | 5 Pages

    Cellular membranes are complex, two-dimensional fluids composed mainly of lipids and proteins, which are constantly in motion. Membrane lipids are organized in a bilayer (two monolayers of lipids forming a single membrane) whereas proteins are scattered throughout the bilayer. The most significant feature of all natural membranes is their flexibility or their ability to change shape without losing their integrity and becoming leaky. Since the forces holding the bilayer are weak non-covalent interactions

  • The Negative Impact Of Fungi On Humans

    1290 Words  | 6 Pages

    IMPACT OF FUNGI ON HUMANS Fungi are eukaryotic, sporulating, heterotrophic organisms which acquire nutrients through absorption. Their vegetative bodies are made up of thalli and reproduce both asexually and sexually, although in some the sexual stage is not known. Various classes exist; basidiomycetes, ascomycetes, deuteromycetes, zygomycetes and oomycetes. The impact of fungi on humans cannot be underestimated. They play vital roles in the ecosystem, including the wellbeing of man. These roles

    The cell wall of fungi is composed of chitin polysaccharide. Protist are also called protozoa, a word meaning “first” or “original” animals. Protist have been grouped together based on general similarities. They can be described as unicellular eukaryotes that are lack cell wall and that are colourless and motile. They exhibit a wide range of morphologies and inhabit many different kinds of habitats. Lastly, viruses are genetic elements that cannot replicated independently of a living cell, called

  • Property Of Life: Characteristics Of Living Organisms

    1618 Words  | 7 Pages

    All living organisms that are considered to be alive must possess certain properties of life. Therefore, scientists have identified seven properties that are served to define life that is shared by all living organisms. The first property of life is order; which states that molecules in living things are arranged in specific structures that consist of one or more cells. Inside each cell, atoms make up molecules; the molecules are what make up the cell organelles and other cellular inclusions. Whereas
