Symplast = water moves across cortex via cytoplasm and plasmodesmata; Water can also seep into cell walls and intercellular spaces; This is called the apoplast; At endodermis there is a casparian strip; Blocks apoplast so all water has to move by symplast; Pericycle pumps ions into xylem; Lowers WP of xylem so water enters xylem by osmosis;
