Stem
The architecture that reaches the light.
The stem is the plant's architecture and its transport highway. It raises the leaves toward the light and carries water and sap between the roots and the leaves. Its way of growing — upright, climbing, creeping, twining, or hidden underground as a rhizome — is a strategy for reaching light and space. Reading a stem means understanding how the plant occupies the world.

To help you understand, learn and master botany, we've created videos on our YouTube channel, in three languages. They let you start whenever you want and dive into the study of plants, at your own pace. Our goal: to leave no one behind. Start however you like, join the communities and learn — together, let's raise the level of botany across the world.
▶ Watch on YouTubeThe forms and habits of the stem
Each part has a role. Look at the photo, read its description — let the plant speak.
Erect stem
Stem that grows vertically and stands upright without support.
Climbing stem
Stem that rises by clinging to a support (tendrils, holdfasts…).
Creeping stem
Stem that runs horizontally along the ground and can root there.
Twining stem
Stem that coils in a spiral around a support to climb.
Rhizome
Horizontal underground stem — not a root — that stores reserves and spreads the plant.
Choose a stem. Does it stand upright, climb, or creep? How does it reach the light? Post your photo.
- 01 Take a photo of the stem and its parts.
- 02 Name what you see: Erect stem, Climbing stem, Creeping stem.
- 03 Post your photo in the group and compare with the community.

La racine — le monde caché sous nos pieds
Après la tige, plongez sous la surface : ancrage, absorption, réserves, symbioses avec les champignons — la racine est bien plus qu’un simple crampon. Nous vous préviendrons par email dès la publication de cette leçon.
