Symplastic route Definition:
In the symplastic route, water and solutes move along the continuum of cytosol. This route requires substances to cross a plasma membrane once, when they first enter the plant. After entering one cell, substances can move from cell to cell via plasmodesmata.

Symplastic route Notes:
The symplast of a plant is the inner side of the plasma membrane in which water and low-molecular-weight solutes can freely diffuse. Symplast cells usually have more than one nucleus. The plasmodesmata allow the direct flow of small molecules such as sugars, amino acids, and ions between adjacent cells. Larger molecules for example transcription factors and plant viruses can also be transported through with the help of actin structures. This allows direct cytoplasm-to-cytoplasm flow of water and other nutrients along concentration gradients across different cells.
