Q
Suggest why it is important that discs are cut from the same beetroot tissue
A
Different parts of beetroot will have different amounts of pigment
2
Q
Suggest why beetroot cylinders are cut into discs using forceps and a scalpel
A
Minimise risk of injury
3
Q
Suggest why beetroot discs are washed in cold distilled water and dried
A
- beetroot cells have been ruptured so pigment will leak out
- ensures that all pigment leaks out due to variable changed
