What is the function of cuticle |
|
Answer» It is also a waxy layer. Cuticle is present on outside of epidermal cells. It reduces rate the of surface transpiration. In some higher plants, the\xa0cuticle\xa0is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.In addition to its\xa0function\xa0as a permeability barrier for water and other molecules (prevent water loss), the micro and nano-structure of the\xa0cuticle\xa0confer specialised surface properties that prevent contamination of\xa0plant\xa0tissues with external water, dirt and microorganisms.The presence of the\xa0cuticle\xa0limits water loss, but also inhibits absorption of carbon dioxide and excretion of oxygen. |
