B2 - Cell Division

Question 1

adult stem cells

Answer 1

stem cells that are found in adults that can differentiate and form a limited number of cells

Question 2

cell cycle

Answer 2

the three-stage process of cell division in a body cell that involves mitosis and results in the formation of two identical daughter cells

Question 3

cloning

Answer 3

the production of identical offspring by asexual reproduction

Question 4

differentiate

Answer 4

the process where cells become specialised for a particular function

Question 5

embryonic stem cells

Answer 5

stem cells from an early embryo that can differentiate to form the specialised cells of the body

Question 6

mitosis

Answer 6

part of the cell cycle where one set of new chromosomes is pulled to each end of the cell forming two identical nuclei during cell division

Question 7

stem cells

Answer 7

undifferentiated cells with the potential to form a wide variety of different cell types

Question 8

therapeutic cloning

Answer 8

a process where an embryo is produced that is genetically identical to the patient so the cells can then be used in medical treatments

Question 9

zygote

Answer 9

the single new cell formed by the fusion of gametes in sexual reproduction
