What is one use of glandular trichomes in plants?

Glandular trichomes are specialized structures found on the surface of many plants that serve a variety of functions, with one of the most notable being the role in repelling herbivores. These trichomes exude sticky or toxic substances that can deter insects and other animals from feeding on the plant. This chemical defense mechanism acts as a primary line of defense, reducing the likelihood of herbivory and thereby protecting the plant's leaves and overall health.

The production of these compounds can also influence herbivore behavior, making the plant less palatable or even harmful if consumed. This adaptation has evolved as a survival strategy, exhibiting the intricate relationship between plants and the herbivores that might threaten them. Understanding this role of glandular trichomes highlights their importance in plant ecology and evolution, particularly in the context of plant defense mechanisms.
