Flowering trees benefit from pollination by bees because their reproductive structures are designed to attract these pollinators through their flowers. The presence of flowers is crucial, as these structures contain both male (stamens) and female (pistils) reproductive parts, allowing for the transfer of pollen necessary for fertilization and fruit production. Bees are particularly drawn to flowers due to their color, scent, and nectar, which are all adaptations that enhance the chances of successful pollination.

Other types of trees, such as evergreens, typically do not have flowers but instead produce cones for reproduction, relying on wind for pollen dispersal rather than insects. Trees that do not produce fruit might also have mechanisms that do not require bee pollination, such as self-pollination or wind pollination. Therefore, flowering trees are specifically adapted to benefit from the services provided by bees, establishing a critical relationship in the ecosystem that supports both tree reproduction and bee foraging behavior.
