Stem cells

Question 1

totipotent

Answer 1

an undifferentiated cell that can form any one of the different cell types needed for an entire new organism

Question 2

blastocyst

Answer 2

an early embryo consisting of a hollow ball of cells with an inner cell mas of pluripotent cells that will eventually form a new organism

Question 3

embryonic stem cells

Answer 3

the undifferentiated cells of the early human embryo with the potential to develop into many different types of specialised cell

Question 4

morula

Answer 4

an early embryo made up of a solid ball of 10-30 totipotent cells

Question 5

pluripotent

Answer 5

an undifferentiated cell that can form most of the cell types needed for an entire new organism

Question 6

adult stem cells (somatic stem cells)

Answer 6

undifferentiated stem cells found among the normal differentiated cells in a tissue or organ that can differentiate when needed to produce any one of the major cells types found in that particular tissue or organ

Question 7

multipotent

Answer 7

a cell that can form a very limited range of differentiated cells within a mature organism
