Cell anatomy

understand and observe cells. Let us begin with the ABC’s of the Cell Theory which splits into 3 major parts: All living beings are made up of cells Cells are the basic unit of structure in all organisms All cells come from preexisting cells. To have a deeper understanding of the statements above, which is, in fact, the simplified version of this vast topic, let’s refer to the Venn diagram below: It shows that in biology, not all living organisms are composed of the same cell.…

body works Cell membrane: A cell membrane is a thin layer that forms a semi- permeable barrier around the outer surface of the cytoplasm of the cell and controls the movement of substances into and out of the cell. Nucleus: It contains DNA for making new cells and organisms and also controls the reaction in the cell. Chromosomes: Thread- like structures found in the nucleus of the cell which carry the genetic information Cytoplasm: The liquid gel which makes up a lot of the body of a cell and is…

Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to…

Cells have specific structures within them that allow them to carry out their functions; these structures are called organelles. Organelles have different functions within a cell that is called Division of Labor. They are also classified in two different groups, membranous and non-membranous. Membranous organelles are surrounded by a membrane while of course, non-membranous are not surrounded by a membrane. When describing the organelles and their function, first will be the membranous…

Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

This can provide information about the way proteins move through cells, interact with other proteins, and implement their effects inside living cells (Stretton et al., 1998; Scott et al., 1998). Flow cytometry, specifically FACS when dealing with GFP tagged proteins, is a way to measure and sort proteins and molecules from a mixed biological sample based on…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

First, I would like to say that the topic I chose is very interesting and in fact I really like this topic. Before choosing my topic I had rough idea about what CRISPR was and how it was being used in recent times to engineer everything around us by small steps. Before my research findings I had an idea what CRISPR was such as how it was being used around the world on modifying genes, and engineering new species by deleting or replacing the genes that were unwanted by that organism. What I knew…

Wi-Fi. They explained the magnetic field is associated with free-radical production. Consequently, free radicals cause damage to cell, cellular structures and molecules such as lips and proteins. Free radicals promote lipid peroxidation by interacting with polyunsaturated fatty acids in the cell membranes. They noted that the damage may occur at the membrane level causing cell death and immortality. Damage can also occur at the DNA level, causing DNA fragmentation. Avendano, Mata, Sarmiento, and…

It is well known that all organisms require at least some water to survive, even the most hardy creature on the planet earth, the tardigrade, Hypsibius dujardini, which can survive near complete dehydration, exposure to extreme radiation, vacuum, temperature and pressure, must be rejuvenated with water if it is to resume life after near complete desiccation (Gabriel, et al. 2007). H. dujardini, famous for surviving some of the harshest conditions of any organism we know of, is a perfect example…
