What is the primary function of the stem in a plant?

The primary function of the stem in a plant is to provide structural support for the plant's leaves, flowers, and fruits, allowing them to be held up and exposed to sunlight for photosynthesis. Additionally, the stem is responsible for transporting water, minerals, and sugars between the roots and the rest of the plant, enabling the plant to grow and survive. While the roots are responsible for absorbing water and nutrients from the soil, and the leaves are primarily involved in photosynthesis and food production, the stem serves as a vital conduit for distributing resources throughout the plant.
