Stem Structure and Function
The stem of a plant has several important functions. It carries water and minerals to the leaves and the flowers. The stem also transports food between the leaves and the roots.
In addition, the stem supports the aboveground parts of a plant. Examination of a bare woody stem will give you a great deal of information about stems. Look at the woody stem. At the tip of this stem and along the side you will notice several structures called buds. The second picture (figure 1.6) shows a longitudinal section of a bud. The outer layers of a bud are called bud scales, which are modified leaves that form a protective covering. If you were to peel away the bud scales, you would find a soft mass of green tissue. This tissue is called the shoot apex. In this part of the bud, cell division occurs and new tissues are produced. Notice that new leaves of the plant can form at the shoot apex.
Not all buds are the same. Notice in the picture of the woody stem that the bud at the shoot tip is called a terminal bud. It usually develops before other buds form. Growth at the terminal bud results in the lengthening of the stem. Leaves and flowers can also arise from the terminal bud. Buds growing along the sides of a stem are called lateral buds. New branches, as well as leaves and flowers, develop from lateral buds.
Each growing season, the terminal bud opens, and the bud scales drop off, leaving a ring of marks around the stem. Notice these bud-scalescars on the stem in the picture. By measuring the length of the stem between the bud-scalescars, you can find out how much the stem grew in length each growing season. Buds are dormant between growing seasons.
A node is the place on a stem where a leaf or a bud arises. The section of the stem between nodes is called an internode. At a node, you can see a leaf scar, the point where an ass a leaf was once attached. Leaf scars can be shaped somewhat like half-moons. If you look closely at leaf scars; you will see tiny spots called bundle scars. These scars are the ends of bundles of vascular tissue that ran from the stem to the leaf stalk.
In many places on the surface of a woody stem, the bark has small, round openings. These holes are called lenticels. 7 function is to allow the exchange of gases, such as water vapor, between the atmosphere and the tissues of the stem.
