They produce tyloses
Study Notes
Tyloses and Pits
- Tyloses are balloon-like outgrowths of parenchyma cells that protrude through the circular bordered pits of vessel members.
- The main function of tyloses is to block water movement.
- Pits are relatively thin areas of the cell wall that allow adjacent cells to communicate or exchange fluids.
- Pits are a characteristic feature of cell walls with secondary layers.
