A "stem" is the main part of a plant that supports leaves, flowers, and fruits. It acts like a backbone, helping the plant stand upright and grow towards the sun. The stem also transports water and nutrients from the roots to the rest of the plant, ensuring it stays healthy. In addition to plants, the term "stem" can refer to the base of a glass, like a wine glass, which connects the bowl to the foot. This part is important for holding the glass without warming the drink. Both uses of "stem" highlight the importance of support and connection in nature and everyday life.
