In some accessory fruits, for example the pome and strawberry, the receptacle gives rise to the edible part of the fruit.

Algae and bryophyta

In phycology, receptacles occur at the ends of branches of algae mainly in the brown algae or Heterokontophyta in the Order (biology), Order Fucales. They are specialised structures which contain the reproductive organs called conceptacles.Fletcher, R.L. (1987). ''Seaweeds of the British Isles.'' Volume 3, Part 1.
