Binary fission

Question 25

What are the 3 types of stem cells?

Answer 25

• Totipotent- Can differentiate into any type of cell. An example is the first few divisions of a fertilised egg • Pluripotent- Can form all tissue types but not whole organisms. Found in early embryos • Multipotent- Only form a range of cells witin a certain type of tissue. Found in bone marrow
