The primary method of nutrient transport in plants is through the process of transpiration, which involves the movement of water and dissolved nutrients from roots to leaves via the xylem. Transpiration creates a negative pressure that helps pull water and nutrients upward throughout the plant. Additionally, the phloem plays a crucial role in transporting the products of photosynthesis, primarily sugars, from leaves to other parts of the plant. This dual transport system is essential for plant growth, development, and overall health.
