*!Leaves are the power-stations of any plant or tree. This is where all the food material is converted into energy for the plant. All leaves can be broadly classified as either simple leaves or compound leaves. A Simple Leaf has only a single leaf blade on its stalk. The stalk of a simple leaf is attached to the plant body. A Compound Leaf is actually a leaf stalk that has more than one leaf blade on it.
