What two things are unique about the pollination biology of orchids?

Orchids exhibit unique pollination Biology through their specialized floral structures and intricate relationships with specific pollinators. Many orchids have evolved complex shapes and scents that mimic the appearance and pheromones of female insects, luring male pollinators to facilitate transfer of pollen. Additionally, orchids often employ a mechanism called "pollinia," which are cohesive masses of pollen that attach to the pollinator, ensuring efficient pollen transfer during their mating process. These adaptations highlight the co-evolution of orchids and their pollinators, leading to highly specialized interactions.
