A "stalk" is a slender, elongated structure that supports a plant's leaves, flowers, or fruit. It connects these parts to the main body of the plant, often referred to as the stem. Stalks can vary in thickness and length, depending on the type of plant, and they play a crucial role in transporting nutrients and water from the roots to the rest of the plant. In addition to plants, the term "stalk" can also refer to the act of following someone closely and secretly, often with harmful intent. This behavior is known as stalking and can involve monitoring a person's activities or movements without their consent, leading to feelings of fear or anxiety for the victim.
