What is a meristem?

Areas in plants where new unspecialised cells are produced by cell division

1

What are stem cells?

They are unspecialised cells (in animals) which have the ability to divide to produce cells that can become different types of specialised cells

2

What is meant by the term differentiation?

It's the process by which an unspecialised cell develops into a specialised cell

3

What are the two main types of stem cell?

Embryonic stem cells and adult stem cells

4

Where are embryonic stem cells found?

Embryos

5

Where are adult stem cells found?

Most of the tissues and organs of the body

6

What is the difference between the two types of stem cell, in terms of the types of cell they can become?

Embryonic stem cells can form any type of cell whereas adult stem cells become specific cell types

7

What are some arguments that agree with stem cell research?

~Helps prevent illness
~stops suffering

8

What are some arguments against stem cell research especially when it is of the use of embryonic stem cells?

~Involves the destruction of embryos
~potential loss of humans

9

Which meristem is responsible for the increase in the length and height of the shoot and root?

Apical meristems

10

Which meristem is responsible for the increase in the width of the stem?

Lateral meristems
