Which part of a flower supports the weight of the flower?

Receptacle
Pedicel
Filament
Sepals

The correct answer is: Pedicel

The part of a flower that supports the weight of the flower is the pedicel. The pedicel is a stalk that connects the flower to the main stem or branch of the plant, providing structural support. This part allows the flower to remain upright and ensures that the various flower organs are positioned for optimal access to pollinators and sunlight. In contrast, while the receptacle is the thickened part of the stem that bears the floral organs and serves as a base for the flower, it does not provide the same level of direct support as the pedicel. The filament is a part of the stamen that holds up the anther where pollen is produced, and sepals are leaf-like structures that protect the flower bud before it opens, but neither serves to support the weight of the entire flower in the same way that the pedicel does.
