Interphase | the period during the cell cycle of a cells growth |
Sister chromatid | two identical chromosomes that make up a duplicated chromosomes |
Centromere | the point on a chromosome by which it is attached to a spindle fiber during cell division. |
Mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
Cytokinesis | the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. |
Daughter cell | a cell formed by the division or budding of another cell; "anthrax grows by dividing into two daughter cells that are generally identical" |
cell differation | In developmental biology, cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. |
stem cell | an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. |
tissue | any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
organ | a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans. |
organ system | In biology, a biological system is a group of organs that work together to perform a certain task. Common systems, such as those present in mammals and other animals, seen in human anatomy, are those such as the circulatory system, the respiratory system, |
