Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain drupes by structure, examples, cultivation and food safety, including allergies and kernel toxicity, and protected names such as PDO pistachios.

A fleshy fruit with a thin skin, fleshy middle and a hard stony endocarp enclosing the seed, such as cherries, plums, peaches, apricots, olives and mangoes; several culinary nuts, including almonds, pistachios and pecans, come from drupe or drupe-like fruits.

What it is for: Food, horticulture and botany.

It can be identify whether a fruit is a drupe; describe drupe structure; handle allergy and kernel safety; find protected designations.

Distinguishing features

Stony endocarp

Usually one seed

Fleshy mesocarp

Includes some culinary nuts

What it looks like

Fruits with a soft flesh around a single hard stone, or nuts inside a husk.

How it is recognised

Single hard stone or pit

Cherries, plums, olives, mangoes

Berries have many seeds without a stony pit
