A number of candidates described the petals in an insect-pollinated plant instead of the anther.
— Examiner report, February/March 2025, 0654/42 Q3(b)(ii) (Cambridge)
Several candidates gave general features of wind-pollinated flowers, such as lots of pollen. These responses were not relevant. The question specifies the adaptations of part Y for wind-pollination. Candidates that recognised this question was about the stigmas generally answered well, often referring to its position as hanging outside the petals or it being feathery.
