I have a practical next week for Biology A2 OCR, and it is assessed so it goes towards our overall grade.
The only information we are given is that it is about stomata distribution?
It is also a qualitative practical which means that the data recorded will not be numerical.
Please please help me!
 
they could ask you which side of the leaf (upper or lower) has more stomata. then you'll need cobalt chloride paper which is blue and turns pink upon contact with water to test whether the upper or lower surface gives off the most water.
