Question

Study the diagram given below that shows the modes of pollination and answer the questions that follow.

1. The given diagram shows three methods of pollination in plants. What are the technical terms used for pollen transfer methods labelled ‘2’ and ‘3’?
2. How does Salvia achieve pollination successfully?

Answer 1

1. Label 2: Geitonogamy, Label 3: Xenogamy
2. Salvia achieves pollination by a lever mechanism. When an insect (usually a bee) enters the flower for nectar, it pushes the staminal lever, causing the anthers to swing down and dust pollen on the insect’s back. Later, when the insect visits another Salvia flower, the stigma touches the same pollen-laden part of the insect’s body, resulting in successful pollination.
