Answer 2

Answer:

There is a unique mechanism in Salvia known as a lever mechanism or turn pipe mechanism. This favours the entomophilic pollination technique, in which insects serve as the pollinators.

Explanation:

• The staminal lever mechanism is responsible for the pollen transfer in salvia flowers.
• In salvia, stamens have been modified to resemble levers, and they play a special role in pollen transfer.
• The morphology of salvia flowers and lever-like stamens was first described by the scientists Hildebrand. Pollen is deposited on the pollinator's dorsal surface during salvia pollination, which is referred to as dorsal or nototribic pollination.
• Salvia has two monothetic stamens that have been converted into levers with a thin ligament connecting the connective and filament, dividing them into upper and lower arms, allowing the stamen to transfer pollen reversibly.
• Where pollinators carry pollen to another flower of the same species for pollination by pushing the lower lever arms and allowing the pollen sac to be on the end of the upper lever arm, which is useful for pressing against or onto the pollinator dorsal or head.
