Which plant has fronds with several to 20 roots per frond and a conspicuous red dot near the center?

The plant in question is characterized by having fronds that can produce several to 20 roots per frond, along with a distinctive red dot located near the center of the frond. This description aligns with the features of giant duckweed.

Giant duckweed is known for its large, rounded, floating fronds that can vary in size and are often accompanied by numerous hanging roots that extend down into the water. The red dot, which can sometimes be seen on the frond, serves as a key identifying feature for this species.

This correct identification is valuable for aquatic weed control, as knowing the specific characteristics of plants allows for more effective management strategies in preventing their spread and proliferation in water bodies. Understanding the traits of giant duckweed helps those involved in aquatic weed management to recognize and address this species efficiently.
