| Simple trichomes are present on aerial surfaces of most angiosperms and on some gymnosperms and bryophytes. |
| Lateral inhibition is also involved in the regular spacing of hair cells or trichomes on root and leaf surfaces. |
| This behaviour clearly indicates that the trichomes are somehow used during the pollinator's life cycle. |
| Indeed, activity, although low, was detected in cotyledon veins and tips and also in leaf veins, trichomes, and hydathodes. |
| Like most labiates, thyme is an aromatic plant with glandular trichomes on the leaves and floral parts contain monoterpenoid essential oils. |
| They also accumulate throughout the leaf in mesophyll tissue and in trichomes. |
