This card explains how stomatal opening and closing are driven by changes in turgor pressure within the guard cells, a process involving active solute transport and cell morphology.
Tato karta vysvětluje, jak otevírání a zavírání průduchů (stomata) řídí turgorový tlak v svěracích buňkách, což je proces zahrnující aktivní transport solutů a buněčnou morfologii.
| Front | Stomata opening/closing 3.1.3(d) |
|---|---|
| Back | - Stomata opening/closing is turgor driven process, when turgor low, guard cells close stomata, once enviro conditions favorable, guard cells pump in solutes by AT, increasing turgor - cellulose helps prevent cells swelling in width (only lengthways), as inner wall less flexible then outer, cells become bean shaped and open stomata, when water scarce, signals trigger turgor low, closing pore |
