Question 1

Stem cells

Answer 1

Cells that can divide by mitosis into two genetically identical cells.
One remains as a stem cell and the other differentiates into a specialised cell by translation part of their DNA

Question 2

Totipotent cells

Answer 2

Divide and differentiate into any type of cell and can produce a whole new organism.
Found up to 8 cell stage in early mammalian embryos for a limited time

Question 3

Pluripotent cells

Answer 3

Divide unlimited times and differentiate into any type of cell.
Found in an embryo

Question 4

Multipotent cells

Answer 4

Divide a limited number of times and differentiate into any limited number of different cell types.
Found in mammal tissues e.g.bone marrow

Question 5

Unipotent cells

Answer 5

Divide a limited number of times and differentiate into one cell type.
