Question

Aquatic plants have the ability to float rather than being submerged in water. How?
​

Answer 1

Answer:

Explanation:

The ability to float rather than being submerged in water in aquatic plants comes due to the presence of a special tissue called aerenchyma which is a subtype of parenchymatous tissue. In this tissue large air cavities are present between parenchyma to give buoyancy to the plants which help them to float rather than being submerged.

Answer 2

$\sf\large \pink{\underbrace{\blue{Answer}}}:$

Aquatic plants float on water because they have buoyancy because of the presence of large air cavities in their parenchyma, and the parenchyma is known as aerenchyma. This makes them float on water.
