All of the following are true regarding the adaptations seen in Vallisneria except:

• B. It's root system is deep-rooted and extensive.
• C. It's stem is hollow and light.
• D. It's leaves are thin, elongated, and ribbon-like.

Answer 1

The correct option is B

It's root system is deep-rooted and extensive.

Vallisneria is a submerged aquatic plant. It's roots are small in size. The stem is hollow and light. The leaves are thin, elongated, ribbon-like so more surface area can be exposed to the light entering the water body for photosynthesis.
