structure of a cell to is a car. The reason I choose to do a car is because it is very similar to the structure of a cell and because to me it was the most interesting choice to choose from. Another reason I choose to compare the cell to a car is because it seemed to be the easiest one for me to do as compared to a Hogwarts or a city. Doing a house or a prison would have also been fairly easy but they were already picked by the people at my table. That wars why I choose to compare the human cell to an automobile

multicellular organisms‚ the cells that make up their respective organisms have different structures depending on their function. The process in which cells get specialized is known as differentiation. Unspecialized cells‚ known as stem cells‚ can be called upon to replace damaged or aging tissues‚ or create new tissue for growth. An example of specialization can be found with blood cells. Every blood cell originates from the bone marrow‚ starting as a unspecialized stem cell known as a multipotential

Stem cells are pluripotent cells present in all living organisms. These cells can differentiate into any type of cell‚ including nerves and cardiac muscle. The scientific community is very excited about the possibility of these undifferentiated cells being used to treat conditions such as spinal cord injuries‚ diabetes‚ and cancer. Despite the enormous potential for medical advancements‚ controversy surrounds the sources and methods of acquiring stem cells and the possible improper uses of the knowledge

discovered the endless possibilities of the so called embryonic stem cells. It has been said that these cells have the ability to repair an entire tissue or even create a copy of it. It is also said to be a potential cure for innumerable serious diseases such as the Alzheimer and the Parkinson’s disease. This is why stem cell research should definitely be funded for the enormous impact it can make in the medical field. Stem cell research is perhaps one of the most controversial topics in modern day

Stem Cell Controversy Stem cells were first isolated and cultured in November of 1998 and have been surrounded with much debate and controversy since day one. “Although the ethical debates have been mostly static and have closely mimicked the ethical debates over abortion‚ the political determinations concerning federal funding of stem cell research have gone through numerous evolutions in the years since the first hESCs were isolated and cultured” (Saltzberg 505). Research is currently being
