Organs

For each plant image in Pl@ntNet, an “organ” is attached to it, in order to identify which part of the plant was photographed.

The term has been broadened in Pl@ntNet to cover a wider variety of shots, such as a canopy taken by a drone, a drawing or a herbarium sheet.

Here is the list of organs available in Pl@ntNet and their definitions:

Leaf

A generally flat, green organ that grows on the stem of plants and serves primarily to capture light to make food for the plant through photosynthesis.

Flower

Part of a plant that contains the reproductive organs and allows for the production of seeds, often colorful or remarkable.

Fruit

The organ derived from the flower that contains the seeds and allows for their dispersal.

Example: green bean pod, samara, banana, pear, hazelnut, acorn, achene, pea, beech nut, etc.

Bark

Outer covering of the trunk, branches and roots of trees.

Habit (entire plant)

Photo of the entire plant, the general appearance of a plant, resulting from its growth and branching pattern.

Branch

Woody extension of a tree or shrub, bearing leaves, flowers or fruits.

Seed

Structure containing an embryo and capable of germinating to give rise to a new plant.

Bud

Small protrusion giving rise to branches, leaves, flowers and fruits.

Aerial photo

Photo of a plant taken from above, usually via a drone flying over a canopy, for example.

Herbarium

One or more parts of the plant pressed on a sheet, annotated, constituting a herbarium sheet.

Drawing

Artistic or technical drawing of a plant or its parts, made by hand.

Uniform background

Photo of a plant on a solid background. Example: a flower placed on a sheet (with or without color), the whole thing photographed.

Anatomy

Microscopic representation of a part of a plant (observed under a microscope).
