This is one of the 12 practical investigations that students studying A level Biology 2015 specifications for England are required to complete.
In this practical, students will prepare and observe dividing cells from the meristems of actively growing garlic root tips. In this improved and simplified protocol, toluidine blue is used to stain the DNA in the meristem cells, instead of the more traditionally-used acetic orcein.
This resource includes full teaching and technical notes, preparation sheets and protocols for the students, plus a Powerpoint for use in class.
