Terrific Trichomes (and Other Specialised Cells) in African Violets: How to Get a Lot from One Plant in the Classroom
Cottrell, Vicki M.
School Science Review, v94 n349 p54-59 Jun 2013
African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and their subsidiary cells; xylem with lignified spirals; petal cells; and pollen grains. The techniques were written with the curriculum for those aged 14-16 in mind, although there is no reason why they could not be used with younger students, or extended for use with post-16 students. (Contains 8 figures and 1 box.)
