bordered pit การใช้

• The bordered pit opens in the cell lumen by pit aperture.
• Bordered pits of the opposite cells form bordered pit pair.
• Bordered pits of the opposite cells form bordered pit pair.
• It slums that torus control the passage of pit through bordered pit.
• Bordered pits are more complex than simple pits.
• Thus the torus closes the bordered pit.
• Bordered pits : In this case, secondary wall border over the cavity of the pits.
• In certain cases, the pit apertures are lenticular or linear or mai .  the pi . t membrane of bordered pit develops an oval thickening in the middle.
• When the water pressure within the xylem reaches extreme levels due to low water input from the roots ( if, for example, the soil is dry ), then the gases come out of solution and form a bubble  an embolism forms, which will spread quickly to other adjacent cells, unless bordered pits are present ( these have a plug-like structure called a torus, that seals off the opening between adjacent cells and stops the embolism from spreading ).
