What is the difference between stalk and stem?

The stalk and stem are terms that often refer to different parts of a plant. The stem is the main structural support of the plant, connecting the roots to the leaves and flowers, while the stalk typically refers to a specific supporting structure of a flower or leaf. In some contexts, “stalk” can also describe the elongated part of certain fruits or vegetables. Essentially, all stalks are stems, but not all stems are stalks.
