This type of structure allows a greater number of leaves can capture sunlight better. Here it causes active cell division resulting in the formation of nodules. These two types of tissues constitute a number of ducts called vascular vessels.

The internodes are responsible for holding the buds or new leaves, while the internodes are the distance between two nodes. The situation in which a tree grows clearly affects the shape and length of the stem. Pollination can be carried away by different pollinators. The bacteria living in the root nodule (and not those in the soil) help in fixation of free nitrogen from the air in the form of nitrates. The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots. The stem carries water and mineral salts absorbed by the root and send it to the leaves.

There are some species that have long and straight stem with relatively few branches, while there are others having which are crooked and/or much branched stem. In trees, tap root is the main axis of the large root system and descends vertically below the stem. However, as the saplings grow into poles and trees, the lower branches fall off giving in a clean bole. Some trees have special roots with a different purpose such as adventitious roots, which may arise from the trunk, branches, leaves or dead branches. The presence of a  long cylindrical bole in a tree is a desirable quality as that increases their timber volume. But sometimes in later life, may be due to some adverse factors the clean bole again develops small branches known as epicormic branches which are defined as branches originating in clusters from dormant or adventitious buds on the trunk of a tree or on older branch when exposed to adverse influence such as excessive light, fire or suppression.

The length of a stem is composed of nodes and internodes. The roots of trees support them firmly to the ground, absorb soil moisture containing mineral salts and send it to stern for onward transmission to the leaves. On the basis of the depth of the root-system, the trees are classified into shallow-rooted and deep-rooted trees. Instead, the trees growing in dense forest have comparatively longer and more or less cylindrical stem. Leaves prepare the food for the plant and send it to its different parts through the stem. Trunk (Stem)—supports the leaves and the branches of the tree and also contains the xylem, the cambium, the phloem, and the heartwood.

Specialized terms Acaulescent: used to describe stems in plants that appear to be stemless. Fluting is considered as a defect as it decreases the basal volume considerably. The trees that develop a long taproot and large lateral roots are not easily uprooted by wind, thus, are called wind firm. They grow out of the branches that extend from the trunk and are usually dense and numerous. Those roots that are produced from parts of the plants other than the radicle or its subdivision are called adventitious roots. According to the growth of stem we can distinguish two types of trees: Trees with exogenous growth: Most of the trees belong to this type of growth. Buttresses are generally associated with the absence of long taproot which could be due to either shallow soil resulting from the presence of rock a little below the surface or badly aerated and infertile subsoil. .
