Which plant is characterized by round floating leaves that are notched at the center with lobes pointed at the tip?

The White Waterlily is characterized by its distinctive round, floating leaves that have a notch at the center and lobes that point at the tip. These leaves typically float on the surface of the water, creating a beautiful display that is recognizable and integral to many aquatic ecosystems.

The structure of the leaves plays an important role in the plant's functions, such as providing shade to the water beneath and aiding in photosynthesis. This unique leaf shape distinguishes the White Waterlily from other aquatic plants, making it easier to identify. The flower of the White Waterlily, which blooms above the water, adds to its identification as well, but it is the specific shape and structure of the leaves that aligns with the description provided.

In contrast, Coontail has a different appearance, lacking floating leaves and characterized instead by its submerged, feathery branch structure. Alligatorweed exhibits distinct, elongated leaves that are not round and floating, and Duckweed consists of tiny, small, floating discs that are generally much smaller and do not have notches or lobes. Therefore, the White Waterlily is the correct choice based on the described characteristics of its leaves.
