blanks.
. Roots are.
developed in aquatic plants.​

Answer 1

Answer:

Aerenchyma is a tissue composed of a network of interconnected gas conducting intercellular spaces which provide plant roots with oxygen under hypoxic conditions. They, therefore, provide the submerged root system of aquatic plants with O2 for respiration and hence well-developed aerenchyma can be said to be a major characteristic of all aquatic plants.

So, the correct option is 'aerenchyma system'.
