symplast การใช้

• The Casparian strip forces water into the symplast at the root endodermal cells.
• Water moving into or out of the xylem, which is part of the apoplast, can thereby be regulated since it must enter the symplast in the endodermis.
• Structurally, the apoplast is formed by the continuum of cell walls of adjacent cells as well as the extracellular spaces, forming a tissue level compartment comparable to the symplast.
• In 1930, Ernst M黱ch coined the term " apoplast " in order to separate the " living " symplast from the " dead " plant region, the latter of which included the cell wall.
