What is Symplast-Apoplast Pathway
The symplast-apoplast pathway is a route of water and nutrient movement through plants. The apoplast is the continuous pathway through the plant cell walls, while the symplast is the pathway through the interconnected cytoplasm of plant cells.
In the symplast-apoplast pathway, water and nutrients can move through the apoplast by traveling through the cell walls and spaces between cells. Once inside the cell, they can then move through the symplast via plasmodesmata, small channels that connect the cytoplasm of adjacent cells.
This pathway allows for efficient movement of water and nutrients throughout the plant, as it can bypass the plasma membrane of individual cells and move through interconnected pathways. Additionally, the symplast pathway allows for communication between different parts of the plant, as signaling molecules can move through the cytoplasm and plasmodesmata to coordinate growth and responses to environmental stimuli.
