Hence, pollination requires the activity of insects that move pollen from male to female flowers, with bees being the most common pollinators.

Then, why do my cucumber plants have flowers but no fruit?

The female flower cannot produce the pollen needed to cause the fruit to develop and is dependent upon insect (or human) pollinators to transport the pollen from the male flower. The male flowers begin forming before the female flowers form. So, it is possible to have cucumbers blooming, but not producing fruit.
