Angiosperms:
– The receptacle is the thickened part of a stem from which flower organs grow.
– In some fruits like pome and strawberry, the receptacle gives rise to the edible part.
– Rubus species have a cluster of drupelets on a conical receptacle.
– In the Daisy family, small flowers are arranged on a round receptacle.
– Raspberry receptacles separate from the fruit when picked, but in blackberries, they remain attached.
Algae and Bryophyta:
– Receptacles occur at the ends of branches of algae, mainly in brown algae.
– They are specialized structures containing reproductive organs called conceptacles.
– Receptacles in algae also capture food.

In botany, the receptacle refers to vegetative tissues near the end of reproductive stems that are situated below or encase the reproductive organs.
