Symplastic transport is a method of movement for water and nutrients within plant cells. It occurs through the interconnected cytoplasm of adjacent cells, allowing substances to flow freely from one cell to another via structures called plasmodesmata. This pathway is crucial for maintaining cellular communication and nutrient distribution throughout the plant. In symplastic transport, materials like sugars and minerals can travel efficiently from the roots to the leaves. This process supports vital functions such as photosynthesis and growth, ensuring that all parts of the plant receive the necessary resources for survival and development.
