04. Flower

The male reproductive part of a flower, consisting mainly of the anther and filament. (AF)

Stamen

The part of the stamen that produces pollen grains.

Anther

A long, thin stalk that supports the anther.

Filament

The female reproductive part of a flower, consisting of the stigma, style, and ovary. (SOS)

Pistil

The receptive surface of the pistil where pollen attaches and germinates.

Stigma

A long, slender stalk connecting the stigma to the ovary.

Style

The enlarged basal part of the pistil that contains the ovules.

Ovary

The base of the flower where the floral parts are attached.

Receptacle

A modified leaf that often attracts pollinators through color, shape, or scent.

Petal

A leaf-like floral structure that protects the developing flower bud.

Sepal

The stalk that attaches an individual flower to the stem or inflorescence.

Pedicel

Structures in the anther where pollen grains develop/ the one who develops the pollen

Microsporangia

Male gametophytes of flowering plants that carry the male reproductive cells.

Pollen Grains

Female reproductive structures inside the ovary that contain the developing female gametophyte.

Ovules

The structure in the ovule where megaspores are produced; the ovule contains the female gametophyte.

Megasporangium

The female gametophyte of a flowering plant that develops within an ovule.

Embryo Sac

A developed ovule that contains the female gametophyte and can become a seed after fertilization.

Mature Ovule

Anther → Microsporangia → Pollen Grains → Male Gametophyte.

Male Reproductive Pathway

Ovary → Ovules → Embryo Sac → Mature Ovule.
