AP BIOLOGY

Detailed explanation-1: -Plants that are adapted to live in aquatic environments are called hydrophytes. They might be fully submerged, partially submerged or floating in water. These plants have special adaptations that help them to survive in water.

Detailed explanation-2: -Wetland plants, or hydrophytic “water loving” vegetation, are those plants which have adapted to growing in the low-oxygen (anaerobic) conditions associated with prolonged saturation or flooding.

Detailed explanation-3: -Large air gaps exist in the parenchyma of aquatic plants to let them float on water. Such a parenchyma type is called aerenchyma. It is a type of tissue with air gaps. It gives hydrophytes buoyancy, allowing them to float to the water’s upper surface.

Detailed explanation-4: -Water lettuce, water hyacinth, duckweed, and other plants are examples.
