Some flowering plants have a long pistil that reaches way above the lower petals. what’s the purpose of this structure?

To receive pollen grains

Explanation:

A flower is a modified shoot which is meant for reproduction. The stamen is the male reproductive organ and the pistil is a flower's female organ. A pistil is located in the centre of the flower and is surrounded by petals, sepals and stamens.

Some flowers have a long pistil that reaches above the petals to receive wind disseminated pollen grains. This helps transfer pollen and fertilize the ova in the ovaries.

explanation:

most inclusive taxonomic category, larger than a kingdom. largest taxonomic group, consisting of closely related phyla. group of closely related species, first part of the scientific name in binomial nomenclature. group of similar organisms that breed and produce fertile offspring.

the fossil record provides evidence of a common ancestor to many species.
