Cells - There are many different cells found in the human body; they have many different shapes and many different functions.
Cells that naturally occur within the mammalian body are collectively called eukaryotic; cells that do not naturally occur in the mammalian body are collectively called prokaryotic.
Question 1

a) Compare and contrast the structure of these two cell types. You must include in your written work, a fully annotated diagram of each cell type. You will need to draw and label your diagrams, scan or photograph them, and embed the diagrams into your assignment.

Erythrocyte has a large surface to help allow oxygen to pass through. Also contains haemoglobin that attaches to oxygen.

Macrophage (white blood cell) are large to help engulf bacteria or viruses. They have long thin pseudo pods that help capture the bacteria or viruses for them to be engulfed, destroyed and digested.

    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 membrane that perform specific functions. The surface of the cell is covered with a thin film or plasma membrane, which is the boundary that separates the living cell from its nonliving surroundings. Plasma membranes are composed mostly of proteins and lipids (Simon, 02/2012, p. 59-60).

The size of a cell is indicative of its function(s). The shape of cells in living organisms may range from concave, to spherical, oval, rectangular, flat, oval, or rod-shaped. The cells can be viewed with the aid of a microscope. Every living organism possesses multicellular and unicellular cells. At the same time, the different types of cells display common structural properties. Examples include the plasma membrane and genetic composition (Jan,

    Eukaryotic cells have their chromosomes contained in a nucleus. Unicellular orgasisms such as amoebas and yeast, or multi-cellular organisms such as plants and animals consist of eukaryotic cells. Human being consist of approximately 1 billion cells per gram tissue. DNA located in 23 pairs of chromosomes is contained in each cell nucleus. Schleiden in 1838 and Schwann in 1839 made very important discoveries that we consist of cells, and Remark discovered that cells prolifarate through division in 1850. Three decades ago, the molecular mechanisms that regulate the cell cycle and thus cell division was able to be identified. It has been known that these vital mechanisms are conserved through evolution and function in the same way in eukaryotic organisms.

  • Important Body System: The Circulatory System

    738 Words  | 2 Pages

    One important body system is the circulatory system. The systems job is to pump blood to all parts of the body. The blood circulates inside of many tubes and blood vessels which are found in your body. Blood vessels carry the blood to all parts of the body. Oxygen goes into the blood every time we take a breath. Carbon dioxide is a kind of gas. The blood carries carbon dioxide from the cells to the lungs. When a person breathes out, the body is getting rid of carbon dioxide. Your circulatory system works twenty-four hours a day, seven days a week. It even works when you are sleeping. The circulatory system delivers food, fluids and chemicals to cells throughout your body. It helps to clear your body of waste and carries cells that fight diseases. If your circulatory system would stop working, your cells would starve. Sometimes a doctor would give a patient a vaccine directly into the circulatory system so the medicine should travel to the parts of the body that need it. The circulatory system is made up of three main parts: the heart, the blood vessels, and the blood. The two main kinds of blood vessels are arteries and veins. There are also smaller vessels called capillaries. Arteries and veins are connected by capillaries. A heart of a human is a muscle. The heart has a left side and right side. On the right side, blood enters the heart from the body and then goes from the right side of the heart and to the lungs. In the lungs, it picks up oxygen and returns to the left side of the heart. The oxygen and the blood are then pumped to the body. The heart contains valves. The valves function is to keep the blood flowing in one direction. Each side of the heart is divided into two parts. The upper chamber is called an...

Granular leukocytes have three subdivisions, they are neutrophils, eosinophils, and basophils. Neutrophils neutralize the bacteria that invade the body, eosinophils digests viruses that had been bound to by antibodies in the blood, and basophils release histamine to intensify allergic reactions and help protect the body from parasites.

  • The Cell

    3247 Words  | 7 Pages

    The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA), containing coded instructions for the behavior and reproduction of the cell and also the chemical machinery for the translation of these instructions into the manufacture of proteins. Viruses are not considered cells because they lack this translation machinery; they must parasitize cells in order to translate their own genetic code and reproduce themselves.

    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.

When Van Leeuwenhoek first discovered cells he described them as looking like monk's cell room. There are two main types of cell Prokaryotes cells and Eukaryotes cells. Eu means true. Eukaryote cells have a true nucleus. Kary means nucleus. Cyto means cell. Prokaryote and Eukaryotes have a nucleus. Pro means before.

    Sally: Embryonic cells are "undifferentiated." Undifferentiated cells have not gone through changes that make some cells into skin cells or muscle cells or brain cells, for example. Undifferentiated cells can become any cell in the body because it can activate any gene on any chromosome, but as cells develop, the DNA of certain cells fold in particular ways making large portions of the DNA inaccessible. This makes sure that the wrong genes do not get turned on at the wrong time or in the wrong place.
