Plants


All plants, including trees, vines, shrubs and herbs, have cell walls that are partially composed of cellulose. Newly-added to this collection are images from the Smithsonian's Department of Botany.

This folder highlights plant species that live in aquatic environments, using water for physical support and/or to produce food.

Herbs

"Herbs" does not refer to a related group of plants, but rather to a common body shape – low to the ground and not woody.

  • Herbs icon

Mosses & Worts

Without a vascular system to carry water within their tissues, mosses and worts stay small and low to the ground.

Palms

Although a few other plants (e.g., cycads) are sometimes called palms, true palms are shrubs, vines, or trees within a single plant family and are known for having a single stem and fan-shaped leaves.

Shrubs

Shrubs (also known as bushes) usually have multiple woody stems, and maintain a low height.

  • Shrubs icon

Trees

Trees encompass a diverse range of woody plants that grow a tall, single stem before branching out and leafing.

  • Trees icon

Vines

Vines are plants with flexible stems that can grow up other plants, on structures, or outwards across the ground, helping ensure better exposure to light and access to new areas for colonization.

  • Vines icon

Plant Structures

The different forms and functions of plant tissues can be seen in these detailed images of blossoms, fruits, stems, seeds, leaves, roots, and more.
