Cutin, stomata and guard cells are used for water loss prevention. These are not needed because Elodea is a water plant.
Gaurd cells of stomata control transpiration.
Cutin is a component that is found in all plants. The function of cutin in the leaves of a plant is to block water from seeping in. It is often seen as a waxy type of substance on the surface.
which has a thicker cutin pine or lilac leaf
There is a waxy layer called the cuticle that reduces evaporation from the leaf. It is produced by the epidermal cells of the leaf.
Yes most gases do.
Guard cells, which open and close stomata. Also, cutin.

yes it is
Yes, cutin is a lipid. Cutin refers to one of two waxy polymers that are the main components of the plant cuticle which covers the aerial surface of the plants. Wax is usually considered as a lipid.

In order to understand why desert plants have cuticles (cutin) you first have to know what cutin is, it's function, and why some plants have it. Then you can begin to answer why plants specialized for desert climate have cutin. Cutin is a fatty, wax-like substance secreted by a plant's dermal tissue system. The dermal tissue is also known as the epidermis which is the outermost layer of cells on all young plant organs. If you consider all of this "waxy stuff" as a whole it is termed "cuticle,"similar to the cuticle above your nails. As you can imagine, wax is insoluble in water and therefore "water-proofs" the skin of the plant. In other words, it dictates how much water is lost through the epidermal cells by evaporation, ensures water does not enter, and also keeps other molecules from entering. The cuticle also protects again UV radiation. Regarding plant's evolutionary history, the adaptation of cutin provided a way for marine plant life to move onto land. Suppose if you were a marine plant and your entire body was surrounded in water, you would rely less on gaseous exchange and evolving structures or mechanisms to trap water within you. If you move onto land and are in hot, dry, desert climates water is scarce and you must adapt to survive. This is why desert plants have cutin. I hope that helps!
