The function of conductive tissue in plants, primarily represented by **xylem** and **phloem**, is to transport vital substances throughout the organism. Xylem conveys water and dissolved minerals absorbed from the soil to aerial parts of the plant, facilitating photosynthesis. In contrast, phloem is responsible for distributing the sugars and nutrients produced through photosynthesis, connecting various plant tissues. This efficient transport system is crucial for plant growth, development, and overall health, enabling them to respond to environmental conditions.
