What does "multipotent" mean?

• able to divide and make all different types of cells
• able to divide and make multiple (but not all) types of cells 
• cannot divide

What does "pluripotent" mean?

• able to divide and make all different types of cells
• not able to divide
• can only divide and make one cell type 
• if it divides, it will make a cancerous tumor
