define the term specialised cell?

Early embryonic cells are meristematic ("stem") and not specialized to do anything in particular. As the embryo develops these cells specialize to perform various specific or specialized functions. Examples: Muscle cells-contraction/movement ; nerve cells-carry impulses ; epidermal cells-covering ; gland cells-secretions, etc.\n  There are several theories as to how these unspecialized cells specialize (or differentiate).

me·tab·o·lism (mĭ-tăb'ə-lĭz'əm)\nn.\nThe complex of physical and chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.\nThe functioning of a specific substance, such as water, within the living body.\n\nWALKING

Hi Anita. I believe the best answer is D) histology.\n\nAnatomy is a much broader area than this.\nCell biology is more concerned with the internal functions of the cell.\nChemistry is not directly involved with how cells are arranged.\nPhysiology is a much broader area of study.\n\nHope this is helpful for you.  Best wishes.

In cell biology, a mitochondrion (from Greek mitos thread + khondrion granule) is an organelle found in most eukaryotic cells, including those of plants, animals, fungi, and protists. A few cells, such as the trypanosome protozoan, have a single large mitochondrion, but usually a cell has hundreds or thousands of mitochondria. The exact number of mitochondria depends on the cell's level of metabolic activity: more activity means more mitochondria. Mitochondria can occupy up to 25% of the cell's cytosol.\n\nMitochondria are sometimes described as "cellular power plants", because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation.

Goblet cells are specialised columnar epithelial cells. There function is to produce mucus - especially in the respiratory and digestive tracts.

Good answer Trampus, lol.\n\nThey are the same thing.  In the US they're called cells and in the UK, mobiles. Dunno why tho.

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word "neuroglia" means "nerve glue." These cells are nonconductive and provide a support system for the neurons. They are a special type of "connective tissue" for the nervous system.\nNeurons\n\nNeurons, or nerve cells, carry out the functions of the nervous system by conducting nerve impulses. They are highly specialized and amitotic. This means that if a neuron is destroyed, it cannot be replaced because neurons do not go through mitosis.

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.
