Flower Morphology

The study of the external form and structure of flowers.

Stamen

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

Anther

The part of the stamen that produces pollen grains.

Filament

A long, thin stalk that supports the anther.

Pistil

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

Stigma

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

Style

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

Ovary

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

Receptacle

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

Petal

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

Sepal

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

Pedicel

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

Anther Structure

The anther contains microsporangia, which produce pollen grains.

Microsporangia

Structures in the anther where pollen grains develop.

Pollen Grains

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

Ovary Structure

The ovary contains ovules, which develop into seeds after fertilization.

Ovules

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

Megasporangium

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

Embryo Sac

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

Mature Ovule

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

Male Reproductive Pathway

Anther → Microsporangia → Pollen Grains → Male Gametophyte.

Female Reproductive Pathway

Ovary → Ovules → Embryo Sac → Mature Ovule.
