Reduction in vascular tissue, mechanical tissue and cuticle is characteristic of :-

  1. Hydrophytes

  2. Xerophytes

  3. Mesophytes

  4. Epiphytes.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Answer is option A i.e. "Hydrophytes"
Hydrophytes are aquatic plants that live in aquatic environments either completely or partially submerged in water. As an adaptation, their vascular tissue and mechanical tissue are reduced. The cuticle is either completely absent or it is reduced, thin and poorly developed.
On contrary, xerophytes have heavy cuticle, vascular tissue and mechanical tissue. Mesophytes have moderate vascular tissue, mechanical tissue and cuticle and epiphytes are lower plants or mosses that live in marine environment, they are non-vascular.
