Size and Position of Floral Anther Plays a Vital Role in Pollination

In their work, Dr. Endress and his colleagues found that the sizes and positioning of the anthers facilitates pollen collection by buzz-pollinating bees . The male floral structures, anthers, release the pollen gradually, like tiny gumball dispensers. Unlike moths and butterflies that are ...
