And now you see why the flower makes 

 nectar. 



It wishes to coax the bees to come. 

 When the bees go down to the bottom of 

 the flower after nectar, they will be sure to 

 get their coats dusty with pollen. Then 

 they fly to another flower, and some of the 

 pollen on their coats is rubbed against the 

 stigma and stuck fast there. 



The nectar is always placed so that the 

 bees have to touch the anthers and the 

 stigma of the flower on their way to 

 the feast. 



Many flowers have bright lines or spots 

 leading to the nectar that the bee may lose 

 no time in finding it. These are called 

 nectar guides, and you can see them very 

 plainly in the morning-glory. 



Many other insects besides bees visit 

 flowers. Butterflies and moths and flies 

 and even some beetles are fond of nectar 

 and pollen, and they all carry pollen about 

 from plant to plant.
