    Eukaryotes and prokaryotes There are only two types of cell in the world, these are eukaryotic and prokaryotic cells. They are both similar and different in many ways, for example prokaryotes are only a few micrometres in size whereas eukaryotes are between 5-100 micrometres and nearly 10,000 times the volume of that of a prokaryote. A chemical similarity between the two is that they both either contain or use proteins, carbohydrates, lipids and nucleic acids to store or create energy. Both eukaryotes

  • Eukaryotic Cells And Its Functions

    “Eukaryotic cells are complex and include all animal and plant cells. Prokaryotic cells are smaller and simpler, e.g. Bacteria” - (AQA 2008) Eukaryotic cells contain membrane-bound organelles, whereas prokaryotic cells do not contain these. Although both of these cells contain DNA, only eukaryotic cells contain a nucleus. The nucleus is the largest organelle, surrounded by a double membrane (nuclear envelope) containing lots of pores. The nuclear membrane protects contents of the nucleus and controls

  • Prokaryotic and Eukaryotic Cells

    853 Words  | 4 Pages

    Prokaryotic and Eukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell were the

  • Eukaryotic And Prokaryotic Of Cells

    two major groups that cells can be grouped into to. These are eukaryotic and prokaryotic cells. All eukaryotic cells contain a plasma membrane, as well as cytoplasm and organelles such as mitochondria, rough endoplasmic reticulum (ER), Golgi apparatus, smooth ER, ribosomes, a nucleus which is surrounded by a double membrane known as the nuclear envelope, and secretory vesicles. There are some eukaryotic cells which contain more organelles as well as theses. Some eukaryotic cells, specifically in plants

  • The Structure Of Eukaryotic Cells

    1416 Words  | 6 Pages

    Describe the Structure of Eukaryotic 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. Nucleus

  • The Membrane Of A Eukaryotic Cell

    968 Words  | 4 Pages

    A eukaryotic cell not only has a plasma membrane as its external boundary, but it also has a variety of membranes that divide its interior into discrete partitions, separating processes and cell mechanisms (National Center for Biotechnology Information, 2012). The complex and varied design of the phospholipid bilayer allows the membrane to serve the variety of specific functions required by different types of cells. Moreover, one of the most significant properties of membranes is selective permeability;

  • Prokaryotic and Eukaryotic Cells Essay

    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

  • A Survey of Eukaryotic Cells and Microorganisms

    A Survey of Eukaryotic Cells and Microorganisms HISTORY OF EUKARYOTES: 1. Evidence indicates that the first Eukaryotic cells first appeared on the earth approximately 2 billion years ago. Fossilized cells appear in shale sediments from China, Russia and Australia the date from 850-950 million years ago. 2. Biologists have discovered evidence to suggest that the eukaryotic cell evolved from prokaryotic organisms by a process of intracellular symbiosis. 3. Some of the organelles that

  • Analyzing The Primary Features Of Eukaryotic Cells

    September 15, 2015 Life 120L Lab Report 1 Abstract The objective of this lab was to observe prepared bacterial cells and to observe and describe the primary features of eukaryotic cells. Also, we investigated the effect of concentration gradient and temperature on the rate of osmosis in an artificial system. Finally, we investigated the effect of solute concentration on the tonicity of cells in plant tissue and Elodea. The purpose of our experiments was to find out whether the effect of concentration

  • Comparing Prokaryotic And Eukaryotic Cells

    891 Words  | 4 Pages

    1. Compare and contrast prokaryotic and eukaryotic cells. Be sure to address cell structure, replication (including DNA replication) and gene expression. The cell structure of prokaryotic organisms is small, only about 1-10 microns in length, and they are also single celled. Prokaryotes contain circular DNA which is held in the nucleoid because they lack a nucleus. The specific organisms that have circular DNA are: mitochondrial, bacterial (eubacteria), and Archaea (Methanobacteria, Halobacteria
