Study Notes

Tyloses and Pits

Tyloses are balloon-like outgrowths of parenchyma cells that obstruct water movement by bulging through the circular bordered pits of vessel members.
Pits are relatively thinner areas of the cell wall that allow adjacent cells to communicate and exchange fluids.
Pits are characteristic features of cell walls with secondary layers.
