What is the function of a stem?

It supports the plant.It also contains the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant.The phloem transports food made in the leaves to the rest of the plants. :)

1. framework that supports the body: muscles and tendons attach to skeleton.\n2. protects internal organs including brain\n3. contains & protects red bone marrow; production of red blood cells and white blood cells\n4. Provides storage for inorganic salts such as calcium: regulates amount of calcium in blood stream.

Stem cell enhancers is a natural botanical extract that helps your body maintain healthy stem cell physiology.  \n\nAdult stem cells are most abundantly found in bone marrow.  Stem cells circulate and function to replace dysfunctional cells, thus fulfilling the natural process of maintaining optimal health. stem cells derived from the bone marrow, travel throughout the body, and act to support optimal organ and tissue function.  Stem cell enhancers are products that support the natural role of adult stem cells.

The main function of carbohydrates is to provide energy, but they also play an important role in: \nThe construction of the body organs and nerve cells \nThe definition of a person's biological identity such as their blood group \nEnergy source and storage \n Gut function and dietary fibre

The brain contains stem cells which can generate new brain cells to replace old ones. \n\nA single brain cell has little function, the function comes from interaction with neighbouring cells. Loss of "hardwired" brain function can be replaced given sufficient growth and training.

stem cells are cells that haven't differentiated into specific types (like liver cells, lung cells, or skin cells). they are very useful for scientists becuase they haven't differentiated and can be turned into whatever cells are necessary. try google to find more about them but try to stay away from anything political.

I have a drawing that shows the various types of shell and tube exchangers. I believe their functions are self evident if you see the cross sectins.\n\nSend me you email address and I'll send the drawing.

It is the function in an organization that determines the amount of materials that the organization will need for a specific business function.\n\nFor example:  The organization that produces the Dawn Soap bottles for Proctor and Gamble have to determine how much raw plastic they are going to need on a day to day basis so that they can produce a sufficient amount of bottle molds to match P&G's production output.

Stem cells are undifferentiated cells that can, under the right conditions, turn into any other kind of cell.  They are of particular interest to scientists in that they may provide a means to replace damaged cells that the body cannot naturally replaced (in the spinal chord, for example).  Stem cells are often talked about (not inacurately) in the context of curing numerous degenerative neurological conditions (Parkinsons, Altzeimers, ALS, etc.) as well as other conditions that can be traced to the malfunction of a particular type of cell (they could be used, for example, to replace insuline-sectreteing cells in type I diabetes).\n\nAlthough I have not heard of a product like the one you mentioned, I would be inclined to say it does absolutely nothing.  Stem cells are only useful if they can be made to differentiate and become a specific type the specific type of cell that is needed, where that type of cell is needed.  Flooding the body with stem cells will not make that happen.  My best guess is that it is an attempt to profit off the wide-spread association of the term "stem cell" with curing uncurable diseases and, by extention, with improved health in general.

A stem cell is a basic cell that hasn't quite decided what to become yet.  It is like a cell on standby waiting for orders from the body.  Once the cell gets orders, it goes where it is needed and becomes whatever type of cell the body needs.\n\nWhen a fetus is developing, stem cells become whatever the infant needs based on the DNA code that the mother and father provide.  They become the bones, organs, muscles, brain, hair, etc.  Later in life, stem cells work to repair damage to the body such as bone breaks, cuts, torn ligaments, etc.  This does not mean that aborted fetuses are the primary source of stem cells; it's just one of the most visible ways of seeing how stem cells are used.\n\nMost of the advancements in stem cell research are actually being done with bone-marrow or umbilical cords.  By getting stem cells from adults or umbilical cords, no infants or fetuses need to be harmed.\n\nThe applications of the research are vast.  Scientist hope to be able to repair damaged nerves to cure blindness, deafness and crippling injuries.  There are also ways of using stem cells to stunt the growth of cancers or repair damage to organs.\n\nI hope that was elementary enough.  Stem cell research is really not as bad as everyone makes it seem.  Think about it--if we can cure breast cancer without harming a single child (born or unborn), isn't it worth considering?

Here is a good website to get you started http://en.wikipedia.org/wiki/Stem_cell_research and there are some good links there as well.  \n\nGood Luck!!!

Stem cell research: There are two basic types:\n \nDefinition of a stem cell   \n\nA stem cell is a "generic" cell that can make exact copies of itself indefinitely. In addition, a stem cell has the ability to produce specialized cells for various tissues in the body -- such as heart muscle, brain tissue, and liver tissue. Scientists are able to maintain stem cells forever, developing them into specialized cells as needed.\n\nThere are two basic types:\n\nEmbryonic stem cells - these are obtained from either aborted fetuses or fertilized eggs that are left over from in vitro fertilization (IVF). They are useful for medical and research purposes because they can produce cells for almost every tissue in the body. \n\nAdult stem cells - these are not as versatile for research purposes because they are specific to certain cell types, such as blood, intestines, skin, and muscle. The term "adult stem cell" may be misleading because both children and adults have them. \n\nIn August 2001, President George W. Bush approved limited federal funding for stem cell research. While stem cell research has the potential to provide major medical advances, including cures for many diseases, stem cell research is controversial.\n\nPotential uses for stem cells \n\nThere are many areas in medicine where stem cell research could have a significant impact. For example, there are a variety of diseases and injuries in which a patient's cells or tissues are destroyed and must be replaced by tissue or organ transplants. Stem cells may be able to generate brand new tissue in these cases, and even cure diseases for which currently there is no adequate therapy. Diseases that could see revolutionary advances include Alzheimer's and Parkinson's disease, diabetes, spinal cord injury, heart disease, stroke, arthritis, cancer, and burns.\n\nStem cells could also be used to gain a better understanding of how genetics work in the early stages of cell development. This can help scientists understand why some cells develop abnormally and lead to medical problems such as birth defects and cancer. By understanding the genetic basis for cell development, scientists may learn how to prevent some of these diseases.\n\nFinally, stem cells may be useful in the testing and development of drugs. Because stem cells can be used to create unlimited amounts of specialized tissue, such as heart tissue, it may be possible to test how drugs react on these specialized tissues before trying the drugs on animals and human subjects. Drugs could be tested for effectiveness and side effects more rapidly.
