After water has moved through the endodermis through the Casparian Strip, water continues to move down the water potential gradient into the xylem vessels through the pits, is movement through the pits apoplastic or symplastic? At first, I thought it was symplastic because pits were formed from plasmodesmata, however, I felt that it was apoplastic because pits are basically hollow, so movement through it doesn’t involve living contents. Please help to clarify, thank you.
