what would happen if there was no cuticle on the surface of leaves in dry and hot place
Answers
Answer:
Yes! Here is your answer!
Explanation:
Short answer is not just the leaf but the plant will die. Here's a brief explanation of what purpose the cuticle's role is in a plants leaf.
While the main function of the cuticular coating is to protect leaves from gaining or losing too much water, it is also a smart membrane, allowing two-way transport of select molecules.
Microfibrils of cellulose or other carbohydrates are thought to form tortuous, branched pathways through the cuticular coating that allow limited transport of water and small water-soluble constituents, such as mineral salts, to and from leaf tissues when a droplet of water sits on the leaf surface. Molecular-scale imperfections or cracks form across the cuticular coating that can fill with water allowing water and water-soluble compounds to pass based on size, shape, electrical charge, and other physical/chemical attributes.[1]
The cuticle regulates the moisture that a leaf is exposed to, that's it's main job. Without that role alone the plant/leaf could either drown or dry out. You can see though, it serves other purposes, besides acting as a moisture barrier, it also protects against viruses for example.
In addition to its function as a permeability barrier for water and other molecules (prevent water loss), the micro and nano-structure of the cuticle confer specialised surface properties that prevent contamination of plant tissues with external water, dirt and microorganisms.[2]
