Xylem vessel elements are cells specialised for the movement of water. Which statement correctly pairs an adaptation of a xylem vessel element with its function?
- ACytoplasm is only found in a thin layer next to the cell walls and does not contain any organelles. This reduces resistance to the flow of water in the xylem vessels.
- BThe end walls between xylem vessel elements have partially broken down, forming end plates. This reduces resistance to the flow of water in the xylem vessel.
- CThe walls of the xylem vessel elements contain cellulose that is hydrophilic and can form hydrogen bonds to water, allowing adhesion of water molecules to the vessel walls.
- DXylem vessel elements have plasmodesmata that connect them with companion cells. The companion cells provide ATP, which is needed for the transport of water.
