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...
