A Shirley Poppy Showing Reproductive Organs 



The petals oj a flower are designed to attract insects. The 



essential organs are the pollen-bearing stamens and the pistil 



joining the ovule at the center oj the flower. This picture shows the 



large number of stamens of the poppy, each with a terminal 



anther, bearing pollen, growing in a circle about the pistil 



with its curiously rounded end, called a stigma, 



designed to receive the pollen. The office 



oj the insect is to transfer pollen 



from the stamens of one flower 



to the pistil of another.
