Which type of water plant is most likely to grow in shallow waters with its roots anchored in the soil?

The type of water plant that is most likely to grow in shallow waters with its roots anchored in the soil is the emersed plant. Emersed plants are characterized by having their roots submerged in the water while their stems and leaves extend above the water's surface. This adaptation allows them to take advantage of light and CO2 from the atmosphere while still being rooted in the aquatic environment.

Emersed plants often thrive in shallow areas of ponds, lakes, and wetlands, where their root systems can access the nutrient-rich soil. This positioning also helps them compete effectively for resources in both terrestrial and aquatic ecosystems. In contrast, floating plants do not have their roots anchored to the soil; instead, they float freely on the water's surface. Terrestrial plants, by definition, grow primarily on land and are not adapted to life submerged in water. Submersed plants do grow entirely underwater, and their roots may not be as firmly anchored as those of emersed plants, making them less suited for this specific environment.

Thus, emersed plants are the most suitable choice for shallow waters with roots anchored in soil.
