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.

Aquatic Plants

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

Desert Plants

Short grasses, sagebrush, creosote bushes, and cacti are just a few of the many plants that can be found in the desert.

Ferns

Instead of having flowers, ferns produce spores directly on on their leaves. These plants usually are found in moist environments.

  • Ferns icon

Grasses

This colorful collection presents both tropical and temperate grasses.

  • Grasses icon

Gymnosperms

Note the variance in shape among gymnosperms; this plant group includes cyads, gingkos, and conifers such as pine trees.

Herbs

The term "herbs" does not refer to one single, related group of plants, but rather to a body shape that is low to the ground and not woody.

  • Herbs icon

Mosses & Worts

Without a vascular system to transport water throughout their tissues, mosses and worts remain small in size and low to the ground.

Palms

Palms are shrubs, vines, or trees in a single plant family, although a few other plants (e.g., cycads) are sometimes called palms. True palms are known for their single stem and fan-shaped leaves.

  • Palms icon

Shrubs

Maintaining a low height, shrubs (i.e., bushes) usually have multiple woody stems.

  • 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

Individual images of blossoms, fruits, stems, seeds, leaves, roots, and more, illustrate the different forms and functions of plant tissues.
