Question

Q)why hydrophytes do not have cuticle on stem or leaves?

Answer 1

hydrophytes lacks cuticle on stems and leaves as they do not have any problem in obtaining water and cuticle is a water covering layer . Hence , why they excrete out extra water by transpiration .

Answer 2

Answer:

The term "hydrophytes" refers to plants that can survive in water and adapt to their surroundings. They either stay completely submerged in the water, like Valisineria and Hydrilla, or have a large portion of their bodies partially submerged, like lotus and trapa. Hydrophytes do not have cuticle on their stems or leaves because they do not need water, and cuticle is a water-covering layer. As a result, they excrete extra water through transpiration.

Explanation:

The cuticle is well known for its roles as a diffusion barrier limiting water and solute transport across the apoplast and for protecting the plant from mechanical and chemical damage, pest and pathogen attack, and other harm. Hydrophytes do not have cuticles because they live in a well-watered environment, so they do not experience water loss. The cuticle is a lipid layer that protects the tissue from water loss. They don't have any trouble getting water. Therefore, hydrophyte stems and leaves typically lack cuticle.
