Detailed explanation-1: -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.

Detailed explanation-2: -Vascular plants have roots, stems and leaves.

Detailed explanation-3: -Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells.

Detailed explanation-4: -Decumbent: stems that lie flat on the ground and turn upwards at the ends. Fruticose: stems that grow shrublike with woody like habit. Herbaceous: non woody, they die at the end of the growing season. Internode: an interval between two successive nodes.

Detailed explanation-5: -These are the nodes and internodes. Nodes are where buds grow into leaves, stems, or flowers. Internodes are the parts of the stem in between the nodes. In most plants, stems are found above the ground.
