1

Cellular Differentiation is

the process by which cells become specialised by expressing certain genes to produce proteins for that type of cell

2

Pluripotent cells are

Embryonic stem cells that differentiate into all cell types

3

Multipotent cells are

Tissue stem cells that can only differentiate into a limited number of cell types found in that tissue

4

Bone marrow cells can differentiate into

red blood cells, white blood cells and platelets

5

A therapeutic use of stem cells is

corneal repair or the regeneration of damaged skin

6

How are stem cells used as model cells?

To study how diseases develop or to use for drug testing

7

What are the ethical issues with using stem cells?

Embryos are destroyed

8

What are somatic cells?

Normal body cells (that are not involved in reproduction)

9

What are germline cells?

Gametes and the stem cells that divide to form gametes

10

How do somatic cells divide?

By Mitosis

11

How many chromosomes do diploid cells have?

46 (23 pairs)

12

How do germline cells divide?

By Mitosis and Meiosis
