The stem of sweet corn, also known as the stalk, plays a crucial role in supporting the plant and facilitating its growth. The corn stalk is typically tall and sturdy, reaching heights of up to 10 feet or more, depending on the variety and growing conditions. It is composed of a fibrous, jointed structure called the culm, which provides strength and allows for the plant to stand upright. The stem is hollow, with nodes that bear the leaves and ear shoots at regular intervals. These nodes are important for the plant's nutrient and water transportation, as the vascular system within the stem allows for the movement of water, minerals, and sugars between the roots, leaves, and ears. The stem is also responsible for storing some of the plant’s energy in the form of carbohydrates, which is later used for the development of the ears and kernels. As the plant matures, the stem becomes tougher and more fibrous, contributing to the overall structural integrity of the corn plant.
