Submerged  parts  generally   have  no  cuticle (waterproof  covering), enabling  the plants   to  absorb  minerals   and  gases  directly  from   the  water.In  addition  being  supported   by   water  ,  they  need   little  of  the  supportive  tissue    found  in  land  plants.Stomata ,  the  gas  exchange  pores ,  are  absent  from   plants   that  are completely  submerged;In  partially  submerged   plants   with  floating  leaves (e.g water  lillies),  the  stomata  are  found   on  the  upper  leaf  surface ,  where   they  can not be  flooded.
