Within all organisms we find cells, they form the life blood of their being. Cells contain the blue prints for all life forms known as D.N.A.
Cellular structure
While complex, cellular structures can also be relatively simplistic in design. Each component of the cell plays a vital role, working together in harmony to provide life.
Initially we must look at the cell membrane. The cell membrane is made up of a maliable ‘skin’ perforated by pores. The structure of the membrane is key to the cells work, allowing it to move freely and split. While this is the case for animal cells, within a plant we find that the cell membrane, rather than …show more content…
• Extrinsic proteins which provide two functions, those situated on the outer layer “attach to carbohydrate chains to form glycoproteins which act as the chemical receptors of the cell”, while those situated on the inner surface attach to the cytoskeleton, working as an anchor to hold the membrane in place” (kent, 2000, p.67)
For the remaining investigation into the cell makeup, I am going to focus on a specialized cell. The specialized cell I have chosen to focus on is a nerve cell within the brain.
“The bulk of the brain is made up of structural cells termed glial cells and astrocytes. Lying in amongst these cells are neurons, specialized cells that conduct electrical impulses along their processes. It has been estimated that the average human brain contains about 100 billion neurons and, on average, each neuron is connected to 1000 other neurons. This results in the generation of vast and complex neural networks that are the mainstay of the brain 's processing …show more content…
are covered with ribosomes which create proteins, the proteins are then carried by the cisternae within the endoplasmic reticulum to their place within the cell. While the ribosomes in this case are attatched to the endoplasmic reticulum, this is not their only position, they can also be found freely within the cell cytoplasm (the area within the cell that contains the cell organelles) The S.E.R is in charge of storing, and secreting non-protein products such as carbohydrates and lipids etc. (kent, 2000,
