According to the provided text and figure, which transport route requires substances to repeatedly cross plasma membranes as they move from one cell to the next?

  • A: Apoplastic route
  • B: Symplastic route
  • C: Transmembrane route
  • D: Both Apoplastic and Symplastic routes

Explanation

The text states: 'In the transmembrane route, water and solutes move out of one cell, across the cell wall, and into the neighboring cell, which may pass them to the next cell in the same way. The transmembrane route requires repeated crossings of plasma membranes as substances exit one cell and enter the next.'
