Ans. 
Plant waxes include complex compounds of alcohols, carbohydrates, acids, esters, hydrocarbons, and their combinations, present at the outside of epidermal cells. These waxes are strongly hydrophobic in nature and act as water repellents.
Thus, they provide protection to the aquatic plants against surface wetting. In land plants, waxes, present in cuticle prevent water loss, such as in dessert plants. Other functions of waxes include energy-storage, self-cleaning and reflection of UV radiation. 
 
 
        
                    
             
        
        
        
 models can be very useful in helping to visualize something or observe how something functions. It can help develop a deeper understanding of a subject or help with making predictions based off that model. 
Hope this helps!
