  • Certain Molecules Across Cell Membranes
    726 words
    The Cell Theory The cell theory states that all living matter is made up of cells and some living organisms consist of a single cell. Other cells serve a special purpose within advanced organisms like nerve cells. One theory of a cell states that the first form of life on this earth consisted of a lot of different types of small proto cells. Proto cells are cell like organism. These organisms were able to reproduce in a very limited environment because they are so simple. After many years some o...
  • New Chromosomes Of The Daughter Cells
    473 words
    Mitosis The Process of Mitosis is the term used to describe cell division for replication. The product at the end of mitosis is two daughter cells both genetically identical to the original (parent) cell. This process is used for growth and repair within an organism and also for asexual reproduction. There are five main stages to mitosis, called Interphase, Prophase, Metaphase, Anaphase and Telophase. Although the process has been divided up into these stages the process of mitosis is actually c...
  • Animal And Plant Cells
    299 words
    Cells were discovered in 1665 by Robert Hooke when he took a piece of cork and looked at it under a microscope. Cork is made up of dead cells but you are still able to see the cells which proved to be interesting to him. He described it as being made up like bricks in a wall and these bricks he then called cells. Due to the size of cells it is nearly impossible to see them without the aid of a light microscope but by using an electron microscope you'd be able to see cells in much greater detail....
  • Water From The Potato Cells
    1,582 words
    I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cells are placed in the tw...
  • Lamin A Into The Nuclear Envelope
    1,045 words
    1. The nuclear envelope is a double membrane extension of the rough endoplasmic reticulum containing many nuclear pore complexes. The lipid bilayer of the inner nuclear membrane is supported by the nuclear lamina, a mesh work of lamin filament located adjacent to the inside face of the nuclear envelope. (Lodish et al 1997) The lamina is proposed to be involved in both organizing chromatin and in DNA replication in interphase cells (Gerace and Burke, 1988). Localization and isolation of nuclear l...

  • Mitochondria A Cell Organelle
    1,102 words
    The diagram below shows a picture of an electron microscope. This is a type of microscope that makes use of a beam of electrons rather than visible light. Because the wavelength of electrons is much smaller than the wavelength of visible light, an electron microscope not only gives a high magnification but it also has high resolution. This means that details can be seen clearly. An electron microscope is very similar to a light microscope in the ways in which it works but, instead of using glass...
