The Nucleus Brain of the Cell
Brain of the Cell The nucleus is literally a membrane-bound organelle and is surrounded by a double membrane. I feel that the nucleus is of the greatest importance in the cell because it is the control center that oversees the metabolic functioning of the cell and it directs all the cells activities. The nucleus is like the head of the cell and without a head the rest of the body is useless. It is the

Plant and Animal Cells
I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types.

Is Stem Cell Research Ethical?
Ethics Behind Stem Cell Research. Is Stem Cell Research ethical? Yes, it is. An embryo which is four or five days old, from which stem cells are derived, is not a human being yet, because it’s brain is nonfunctional and it’s heart is not beating. So destroying it would not be murder, it’s just a beginning of a long process of obtaining stem cells from it. Ronald Reagan, The Ethics Committee of the American Society
