141
What is the first thing that happens when a pathogen enters the immune system?
Pathogens have antigens on their surface that are uniquw to them, there is a corresponding antibody on the lymphocytes.
142
What is the second thing that happens when a pathogen enters the immune system?
The antigen binds to its corresponding antibody on the lymphocyte which activates it.
143
What is the third thing that happens when a pathogen enters the immune system?
This lymphocyte then divides over and over again to produce clones of the lymphocytes.
144
What is the fourth thing that happens when a pathogen enters the immune system?
Some lymphocytes secrete larger amounts of antibodies. The antibodies stick to the antigens and destroy the patho
145

How can plants be cloned through cuttings?>
You remove a small piece of the plant and dip the end in rooting powder which contains plant hormones and this encourages the plant to develop roots. This only works for a few clones.
149
How can tissue culture make clones
e take a plant and divide it into hundreds of tiny pieces. These small groups of cells are incubated using plant hormones and the plant hormones stimulate the plant hormones to grow and develop into fully grown clones. Must be sterile conditions as we don't want to introduce microorganism such as bacteria or fungi. Useful in commercial plants. Quick and cheap. Conserve ex

Give a reason why the three domain method of classification has been
suggested.
(1)
....................................................................................................................................................................................................
```
(improved) genetic analysis (1)
• DNA/RNA {screening/sequencing} (1)
• domain theory is based on genetics (1)

```
158
Describe the lytic pathway?
```
the viruses use host cell
machinery (1)
• {viral genetic material /
viral proteins} are made
by the cell (1)
• new virus particles
assemble (1)
• lyse host cells (to release
viral particles)

164
Why is only leaf peel used?
```
the leaf peel is thin / leaf is too
thick (1)
• as the leaf peel allows light to
pass through it/the leaf would
not allow light to shine through it
(1)
• to enable the {stomata / cells/
guard cells} to be identified (1
