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.

| 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. |
| Uniqueness | While there are numerous images of plant hairs available on line, this presentation provides a collection of images and micrographs of hairs from a variety of plants with explanation of their functions. |
