Here's why:

* Made of many cells: Daffodils, like all plants, are composed of numerous cells that work together to form tissues, organs, and ultimately the entire plant.

* Specialized cells: These cells have different functions, like photosynthesis in leaves, water transport in roots, and reproduction in flowers.

* Complex organization: The cells in a daffodil are arranged in a complex and coordinated manner, forming structures like stems, roots, leaves, and flowers.

In contrast, single-celled organisms like bacteria or amoebas are not considered multicellular.
