Science Flower Anatomy and Pollination

A set of vocabulary flashcards reviewing the anatomical structures and terms related to angiosperm flowers and pollination.

Angiosperm

Flowering plants that undergo reproduction involving specific male and female flower parts.

Stamen

The male reproductive structure of a flower, which includes the filament and the anther.

Filament

A stalk within the stamen that supports the anther.

Anther

A fluffy structure of the stamen that produces pollen.

Pistil

The female reproductive structure of a flower, composed of the stigma, style, and ovary.

Stigma

The sticky structure of the pistil where pollen is intended to stick.

Style

The stalk of the pistil that supports the stigma.

Ovary

The structure at the base of the pistil where fertilization occurs, seeds are formed, and which ripens into a fruit.

Sepals

Non-reproductive floral parts that protect a developing flower bud.

Petals

Structures of the flower that are neither male nor female and help attract pollinators.

Pollinator

An organism, such as a hummingbird, butterfly, or bee, that transfers pollen between flower structures.

Nectar

A sugary sweet substance produced by many flowering plants that acts as a major source of carbohydrates and energy to attract pollinators.
