Organs

For each plant image in Pl@ntNet, an “organ” is attached, in order to identify which part of the plant has been 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

Generally flat and green organ that grows on the stem of plants and that mainly serves to capture light to make the plant’s food through photosynthesis.

Flower

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

Fruit

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

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

Bark

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

Whole plant (habit)

Photo of the whole 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 outgrowth giving rise to branches, leaves, flowers and fruits.

Aerial

Plant photo 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

Plant photo on a uniform background. Example: a flower placed on a leaf (with or without color), all photographed.

Anatomy

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