Stem Cell Essay Sample

The function of a specialized cell is related to its structure because you would need the correct structure for a function to work. For example, a hand and nose are two different types of structures and they both have different functions. Obviously, the hand is made so that it can do stuff, such as pick up food, while the nose is made to breath. If the structures of the hand and nose were switched, then those functions wouldn’t be able to still work, because how can you pick up food with the structure of a nose. Therefore, the structure of a cell does determine what the function will be. Those are the reasons why cells in multicellular organisms aren’t all the same, because different structures determine how the cell is going to function. Specialized cells make the organisms more efficient in energy use and staying alive because it helps you to live your daily life style. For example, the feet are structured so that you can walk and the hands are structured so that you can pick up stuff. If the structures were the same, then we definitely won’t be able to do those types of things.

Stem cells are first made as unspecialized and have no use, but they are able to go through the process of mitosis. Later on, stem cells are used to help out the body if something is wrong. the quote “In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive.” (HIOF, 2009) meant that when a stem cell divides, that stem cell will either stay a stem cell or become a cell with a specialized function such as a brain cell. Stem cells are important in normal development because it is the reason for having specialized cells such as the heart, lung, skin, sperm and eggs.

There are two types of adipose cells, white and brown. The white adipose cell contains large fat droplets, a small amount of cytoplasm, and flattened nuclei, while the brown adipose cell contains fat droplets of different sizing, large amounts of cytoplasm, a number of mitochondria and a round nuclei.

Epithelial cells from the trachea help to move the mucous upwards and out of the respiratory tract so that it can clean the pathway. The Epithelial cell are covered with goblet mucosal cells which are covered by Microvilli. The structure is long so that there is room to take out mucus to clear the pathways, though if the structure gets damaged, then it can cause life threatening attacks.

The things that I have learned about cell diversity are how a structure of a specialized cell is related to its function. Its structure determines its functions because the structure needs to be the right shape and size to do the necessary functions it is assigned to. The concept “Structure determines function” is important to human physiology because we need to know that every cell is many different kinds of shapes and that helps them to have different functions. Depending on how a cell looks like can determine its function because of how it is used.

The biology of neural stem cells

Stem cells are originally defined in the haematological system, but recently have been found in a multitude of other sites. These cells all share the same features of self-renewal and multipotentiality and different types and therapeutic strategies have been defined with respect to the nervous system. There are three known accessible sources of autologous adult stem cells in humans: Bone marrow, Adipose tissue (fat cells) and Blood....

Research Question: To investigate how different temperatures affect the beetroot pigment and finding out the absorbance and transmittance % using a visible spectrophotometer. Background Information: Beetroots contain betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any...

Investigating Transport Across Membranes

Introduction The cell membrane is the boundary that separates the internal parts of the cell from surroundings. Substances that move in or out of the cells must pass across the cell membrane. Beetroot (Beta vulgaris) cells contain red pigment called betacyanin. The red pigment is contained in a large vacuole inside the cells. The vacuole is separated from the cytoplasm of the cell by its...
