What are apoplast and symplast?

There are two types of transport pathway for the conduction of the water from one region to the other. The path followed by the water can be symplast or apoplast pathway. The symplast is the pathway in which the water molecules moves through the plasmodesmata region in the cells. The symplast is the living region present between two cells which connects one cell with the other. The apoplast pathway is the path in which the water is moving between the intercellular spaces. The apoplast includes the non living spaces between the cells and the cell membranes.
