Detailed explanation-1: -Stems support the whole plant and help it to stand erect. It also helps in the transportation of food and water. At the same time, the function of leaves is to prepare food by the process called photosynthesis. Thus, it is not the leaf but it is the stem that holds the plant upright.
Detailed explanation-2: -Stem is an essential part of the plant that provides mechanical support to the whole plant body. Every other part of the plant except the one underground, depends on stem for support. This includes the leaves, fruits, flowers, branches etc.
Detailed explanation-3: -Stems hold plants upright, bear leaves and other structures, and transport fluids between roots and leaves. Like roots, stems contain dermal, ground, and vascular tissues. Trees have woody stems covered with bark.
