See it

Bone-marrow stem cells form blood cells. Embryonic stem cells can form a wider range of cell types. Plant meristems can produce new tissues throughout life.

Try it together

Build a benefit-risk table for using stem cells to replace damaged nerve cells.

Now you try

1. Define differentiation. 2. Give one adult stem-cell location. 3. Explain one medical benefit and one concern.
