Question

Insect pollinated flowers have brightly coloured petals and have sticky pollen grains. Why?

Answer 1

Insect pollination is the transfer of pollen grains from anther to stigma by insects. Insect pollinated flowers produce brightly coloured petals and sticky pollen grains because:-

1. Brightly coloured petals attract insects because they are easily visible to insects from a very far distance.
2. Sticky pollen grains get easily attached to the insect body.
