Varieties of water milfoil that have leaves only present near the surface of the water do so as an adaptation to available light. Only the top of a plant in murky water gets light, so it saves energy for the plant to not have too many leaves.
a water milfoil has it's leaves close to the water surface to get water easily using it's xylem vessels in the leaves
The water milfoil leaves floating on the water's surface are there to catch the sunlight and so aid in photosynthesis.
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
Due to photosynthesis the water is present in the leaves,hence when we crush the fresh leaves and flower we see water
The leaves of the water lily sit on the water, but the lotus rises and it's leaves sit up to four feet above the surface.
This process is called transpiration. This process is basically the evaporation of water from plant leaves through the stomata that are small pores on leaves. For this to occur, a plant draws up water from the soil.
Waxy layer on outer surface of green plants is called cuticle .This cuticle is actually present in outer cell walls of epidermal cells . The wax present in cuticle is a type of lipid . It is waterproof layer which prevents excessive loss of water by transpiration . It also protects plant from abrasive damage. Wax is chemically a mixture of esters of long chain fatty acids eg cerotic acid , montanic acid , long chain alkanes , alcohols , ketones .

A water milfoil is an aquatic plants with finely divided leaves that are submerged in water. They have long floppy stems in order for the plant to bend without breaking in the water's current.

So tthey can absorb as much sunlight as possible
Milfoil is a term that encompasses two plant species. The most common of these is achillea millefolium which is also known as yarrow. Aquatic Myriophyllum plants are often called water milfoil.
Water milfoil is a flowering plant despite living in water. Its flowers need to be pollinated in order for it to make seeds. It is wind pollinated so the flowers need to be above the water.

could be water hyacinth Yes, water Hyacinth's do float on the water surface. Hyacinths have leaves that look like hippo ears. Water lilies also float on the water surface. They have flat leaves that fill the water surface and the flowers poke up among the leaves. Patti Rose www.rosepond.com
Water vapour leaves the leaves of a tree through pores in their surface.
