Scale-like trichomes serve multiple functions, primarily aimed at protecting the plant. These include:
Reducing Water Loss: The overlapping structure of scale-like trichomes creates a barrier that minimizes evaporation, helping the plant conserve water. Reflecting Light: The reflective properties of these trichomes protect the plant from excessive sunlight, reducing the risk of damage from UV radiation. Defense Against Herbivores: The physical barrier formed by scale-like trichomes can deter herbivores and insects from feeding on the plant. Protection From Pathogens: By creating a physical barrier, these trichomes can also help prevent the intrusion of pathogenic fungi and bacteria.
