Cell Differentiation – Stem Cells• how specialized cells get produced• controlled by the cell’s DNA• stem cells are animal cells that can differentiate into many cell
types• 2 types of stem cells:
Embryonic – can differentiate into any kind of cell
Tissue – can only differentiate into certain types of cells, ex. umbilical cord blood

SPECIALIZED CELLS
• Many complex organisms, such as a human being or a
maple tree, begin life as a single fertilized egg or a single cell.
• The cells in a complex organism are not all identical. They perform different
functions so have a different designs or are specialized.

SPECIALIZED CELLS
• Plants also have specialized tissues
