Lock fruit
A closing fruit is a fruit that drops in the closed state of the plant and also in the maturation does not open. The unit of spread is therefore the fruit itself. Edible fruits are ingested by animals and the seeds are excreted in the faeces.
The closing fruits include:
- Berry , collective fruit , with a fleshy pericarp
- Drupe , mostly solitary, mostly upper ovary , fleshy, usually a carpel
- Nut fruit , often solitary, hard, thick shell
- Caryopsis , lonely, pericarp thin, fused with the seed
- Achene , solitary, thin pericarp, only fused to the seed at one point
- Wing fruit (Samara) (simple), solitary, nut-like with a paper-like pericarp that grows into a wing-shaped structure.
- Utricle , mostly solitary, pericarp loose and puffy (inflated), often paper-like
