stem cells

• embryonic stem cells can turn into any type of cell
• differentiation is when a cell changes to become specialized for its job
• differentiated cells can divide to produce more undifferentiated cells
• stem cells are found in early human embryo
• adults have stem cells but are only found in certain places like bone marrow
• stem cells from embryos can be grown in a lab to produce clones or to produce cells that can be used to treat diseases
• people believe human embryos shouldn't be used for experiments since each one is a potential human life
• people think that curing patients who already exist and who are suffering is more important than rights of embryos
• stem cells can produce identical plants
• in plants stem cells are found in the meristems
• throughout the plants life cells in the meristem tissue can differentiate into any type of cell
• stem cells can be used to produce clones of plants
• the can be used to grow more plants of a rare species
