Answer 2

Answer:

"Plants", whose stems are "light and spongy" on water are called "Aquatic plants".

Aquatic plants are plants that "float in water" or are "partially or totally submerged in water". In this case, the plants that float on the surface of the water require stems that must be light and spongy to enable the plant to float easily on the surface of the water. Examples of such aquatic plants can be Water Poppy, Water Hyacinth.
