Receptacle

The part of a flower that supports the flower structure.

Sepals

Green structures that protect the bud of a flower before it opens.

Petals

Colorful parts of a flower that attract pollinators.

Stigma

The part of the pistil that receives pollen during fertilization.

Style

The slender part of the pistil that connects the stigma to the ovary.

Ovary

The enlarged base of the pistil that contains ovules.

Pistil

The entire female reproductive structure of a flower, including stigma, style, and ovary.

Anther

The part of the stamen that produces pollen.

Filament

The stalk that holds up the anther in a flower.

Stamen

The entire male reproductive structure, including anthers and filaments.

Nectaries

Structures in flowers that produce nectar to attract pollinators.

Perfect flower

A flower that has both male (stamen) and female (pistil) reproductive parts.

Imperfect flower

A flower that has either male or female parts, but not both.

Wind-pollinated plants

Plants that rely on wind to distribute pollen, often lacking petals.

Fused parts

When adjacent flower parts are connected together, creating a single structure.

Clustered flowers

Multiple flowers grouped together to enhance the signal to attract pollinators.

Modifications

Changes in flower structure or design to serve different functions, such as attracting pollinators.

Chemical recognition in pollen

The ability of some plants to identify their own pollen and prevent fertilization.

Pollination

The process by which pollen is transferred from anther to stigma.

Self-pollination

The transfer of pollen from one flower to its own stigma, leading to potential asexual reproduction.

Functions of petals

To attract pollinators and provide a landing platform for insects.
