| Blastocyst | stage of early development in mammals that consists of a hollow ball of cells |
| Pluripotent | cells that are capable of developing into most, but not all, of the body’s cell types (ALMOST ALL) |
| Stem Cell | unspecialized cell that is capable of evolving into many different types of specialized cells within the body |
| Multipotent | cell with limited potential to develop into many types of differentiated cells (SOME) |
| Binary fission | type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells |
| Malignant | tumors that invade surrounding tissues and spread throughout the body |
| Metastasis | cancer cells break away from the original (primary) tumor, travel through the blood system, and form a new tumor in other organs or tissues of the body |
