The leaves on an apple tree are alternately arranged on the branch, deciduous, simple, serrated, and unlobed ( no lobes).

oposite
Oak leaves are alternate. Only maples, ashes, viburnums and a few others have opposite leaves.
A Flowering Dogwood tree has simple leaves, not alternate. The leaves are arranged in an opposite pattern on the stem.
Leaves can be classified based on their arrangement on the stem into alternate, opposite, or whorled. In alternate arrangement, leaves are staggered along the stem; in opposite arrangement, they grow in pairs across from each other; and in whorled arrangement, three or more leaves encircle the stem at one point.
