Which statement correctly describes the function of co-transporter proteins in sucrose movement?
- ACo-transporter proteins pump hydrogen ions into phloem sieve tubes along with sucrose.
- BHydrogen ions diffuse through co-transporter proteins with sucrose into companion cells.
- CPlasmodesmata move sucrose into phloem sieve tubes via co-transporter proteins.
- DSucrose is moved through co-transporter proteins by active transport.
