Quizplus · Accepted Answer

Nectar is a sweet substance secreted by many angiosperms as a reward for their pollinators. It is rich in sugars and provides energy for the insects or birds that consume it. This helps ensure that the plant's pollen is transported to other flowers, leading to successful pollination and reproduction. Other choices, such as pollen, honey, and phloem sap, may have various roles in the plant's biology, but they are not usually used as an attractant for pollinators. "Honey Dew" is a sweet, sticky substance excreted by some insects, such as aphids, but it is not produced by plants.
