Why are some plants hairy?

These slides contain information about plant hairs called trichomes. The slides can be used to demonstrate plant structural adaptions to biotic and abiotic conditions. Slides which feature confocal/fluorescence microscopy may be useful as examples in a cell biology class.

Intended End User Role
Educational Language
Pedagogical Use Description Slides 1-5 define trichomes and provide examples of different forms.
Slides 6-10 provide examples of how trichomes act as herbivore deterrents.
Slides 11-13 explains how trichomes can be viewed by confocal/fluorescence microscopy. These slides can be used to describe confocal/fluorescence microscopy and also to demonstrate autofluorescence of plant pigments.
Slides 14-20 focus on the UV-absorbing ability of trichomes and provide confocal images for several examples.
Slides 21-23 show other types of unique adaptations. These include trichomes from sundew and highly branched trichomes in an aquatic plant.
Slides 24-26 present the biochemical nature of trichomes, which act as deterrents but also have medicinal and household uses.
Slides 27-28 provide references and acknowledgements.
