Apoplast transport refers to the movement of water and solutes through the cell walls and intercellular spaces of plant tissues, bypassing the cell membranes. This pathway allows for efficient transport of nutrients and water from the roots to other parts of the plant, as it does not require energy expenditure. In apoplast transport, substances move through the apoplast, which includes the cell wall and the intercellular spaces. This method is crucial for maintaining plant hydration and nutrient distribution, especially in areas where rapid transport is necessary, such as during growth or in response to environmental changes.
