How do plants keep diffusion going to provide continuous nutrients to leaves?

Plants maintain a continuous supply of nutrients to their leaves through a combination of transpiration and active transport. Transpiration creates a negative pressure in the leaf's air spaces, drawing water and dissolved nutrients upward from the roots through the xylem. Additionally, active transport mechanisms in the roots help to absorb essential minerals from the soil, which are then transported through the vascular system to the leaves. This coordinated system ensures a steady flow of nutrients to support photosynthesis and overall plant health.
