What are the microscopic, barbed bristles covering Opuntia fruit and pads called?
Answer
Glochids
The text specifically identifies the microscopic, barbed bristles that cover the entire plant structure, including the fruit's skin, as glochids. These structures are distinct from the larger, more easily visible spines. Glochids pose a significant hazard because they are nearly invisible and detach easily, lodging themselves in the skin or mucous membranes, leading to intense irritation. Proper preparation must address these minute defenses, as they are a primary obstacle to safe consumption, regardless of whether one is preparing the fruit or the pads.
