Flower Parts Diagram: Petals, Stamens, and Pistil Explained
Explore a labeled flower parts diagram that separates petals, sepals, stamens, anthers, filaments, stigma, style, ovary and ovules.
Start With the Core Structure
A flower parts diagram works best when the outer whorls are separated from the reproductive structures at the center. The figure below is a general flowering-plant model; flower shape, number of parts and pollination strategies vary across species.
Use the flower parts diagram to create a focused draft, then review it against the concepts below.
Outer whorls provide context
Sepals protect the developing bud and petals often help attract pollinators. Their shape and color vary, so a generic diagram should state that it is an introductory model rather than a species identification.
Stamens include anther and filament
The stamen is the male reproductive structure. Its filament supports the anther, where pollen is produced and released. Keep the two labels adjacent but distinct.
The pistil or carpel has a route from top to base
The stigma receives pollen, the style connects it to the ovary, and ovules sit inside the ovary. Showing this route prevents the common error of placing pollen directly on an ovule label.

Flower Parts Diagram Reference Key
| Label or stage | Position or relationship | Meaning and drawing check |
|---|---|---|
| Petal | Outer showy whorl | Often involved in pollinator attraction. |
| Sepal | Outer protective whorl | Protects the bud; may resemble a petal. |
| Anther | Tip of a stamen | Produces and releases pollen. |
| Filament | Supports anther | The stalk of the stamen. |
| Stigma | Top of pistil/carpel | Receives pollen. |
| Style | Below stigma | Connects stigma to ovary. |
| Ovary and ovules | Base of pistil/carpel | Ovules are enclosed inside the ovary. |
Create a Focused Teaching Figure
Set the scope. Choose the audience, view and labels before adding extra detail.
Generate a focused draft. Use the prompt below as a starting point. Keep labels and arrows separate so the figure remains editable.
Review before sharing. Check every label, connection and model assumption against the cited sources.
Create a labeled flower parts diagram in cross-section. Show petals, sepals, stamens with anthers and filaments, and one central pistil/carpel with stigma, style, ovary and ovules. Use short editable labels and a general flowering-plant model. Do not imply a species-specific morphology.
Choose Editable Diagram for movable shapes and labels, or Science Drawing for an illustrated draft. An account and available credits are required for generation. Review the model before sharing.
Common Questions
What are the main parts of a flower?
A common introductory model includes sepals, petals, stamens and a pistil or carpel.
What is the difference between anther and filament?
The anther is the pollen-producing tip; the filament supports it.
Where are ovules located?
Ovules are inside the ovary at the base of the pistil or carpel.
