Answer 1

• Wolffia flower

Each Wolffia flower consists of a single pistil and stamen; it also produces the world's smallest fruit, called a utricle. The plant is found in quiet freshwater lakes or marshes with species worldwide. Since the plants have no roots, they can easily float on the surface of the water, where they resemble cornmeal.
