Filament

The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops. The word filament is from the Latin word filum, which means "thread."

Stigma

The stigma is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings.

Stamen

Flowers house the female and male reproductive structures. The female reproductive part is called the pistil and is comprised of the stigma, style, and ovary. The male reproductive part of a flower is referred to as the stamen and consists of the filament and the anther

Receptacle

In botany, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem from which the flower organs grow. In some accessory fruits, for example the pome and strawberry, the receptacle gives rise to the edible part of the fruit

Ovules

In seed plants, the ovule ("small egg") is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: The integument(s) forming its outer layer(s), the nucellus (or remnant of the megasporangium), and female gametophyte (formed from haploid megaspore) in its center.

Anther

The male reproductive part of a flower is called the stamen. It is composed of a long tube, called a filament, and has a pollen-producing structure on the end. This oval-shaped structure is called the anther. It is crucial in the reproduction of flowering plants, as it produces the male gametophyte, known as pollen

Ovary

a female reproductive organ in which ova or eggs are produced, present in humans and other vertebrates as a pair

Pollen

a fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower or from a male cone

Pollen Tube

a hollow tube that develops from a pollen grain when deposited on the stigma of a flower. It penetrates the style and conveys the male gametes to the ovule

Pedicel

a small stalk bearing an individual flower in an inflorescence

Sepal

each of the parts of the calyx of a flower, enclosing the petals and typically green and leaf-like

Petal

each of the segments of the corolla of a flower, which are modified leaves and are typically colored

Pistil

the female organs of a flower, comprising the stigma, style, and ovary
