    How would you differentiate between apoplast and symplast?
The apoplast is the continuous space outside the plasma membrane, while the symplast consists of the interconnected cytoplasm of adjacent cells.
Both apoplast and symplast are pathways for intracellular transport, but the apoplast uses vesicles while the symplast relies on diffusion.
The apoplast is the network of interconnected plasmodesmata, while the symplast refers to the cell walls and intercellular spaces.
The apoplast and symplast are both located within the cell cytoplasm, but the apoplast is specifically associated with the endoplasmic reticulum.
