Answer 1

$\huge\pink{\mathcal{♡Answer:-}}$

They are light in weight as they have hollow spaces filled with air. Ex- duckweed. Fixed plants are fixed in water and cannot move. Underwater plants are found deep under the water bodies.

Terrestrial plants fall under the large category of land plants. Land plants are the kind of plants that get the nutrients they need to survive both from the air and the soil. These plants can't survive if immersed or submerged in water as they'll become waterlogged and die.

Fixed plants: Some plants like water-lily and lotus have roots that fix the plants in the mud at the bottom of the pond. They are known as fixed aquatic plants. Roots of such plants are fixed in the soil at the bottom of a pond. They have plate-like leaves that float over the surface of water.
