A turgor-operated valve is a structure found in some plants that regulates the opening and closing of pores known as stomata. This valve responds to changes in turgor pressure within the guard cells surrounding the stomata, allowing the plant to control gas exchange and water loss.
What else can I help you with?
Why are stomata and guard cells called turgor operated valves?
Stomata and guard cells are called turgor-operated valves because their opening and closing are regulated by changes in turgor pressure within the guard cells. When the guard cells become turgid from water uptake, they bow outwards and cause the stomatal pore to open. Conversely, when the guard cells lose water and become flaccid, the pore closes.
What term describes the condition plant cells require?
Plant cells require turgor pressure to maintain their structure and function. Turgor pressure is the pressure exerted by the fluid content within the cell against the cell wall. It helps provide support and rigidity to the plant.
What is the Function of outlet valve?
To prevent backflow of blood into the Ventricles.
What is a sentence for the term turgor pressure?
When the turgor pressure is low in a plant it will start to slouch and wilt.
What is the function of valve stem seals?
Valve stem seals help prevent oil from leaking into the combustion chamber through the valve guides. They also help control the lubrication of the valve stems and guide them properly within the cylinder head.
What the function of motor operated valve actuator?
The main function of a valve actuator is to control the valves ON to Close or modulating the valve,and the motor operated valve actuator is one important kind of valve actuator,the main different between kind valve actuators is it drive by electric power.
What is function of solenoid?
The function of solenoid can be quite diverse. This is a valve that is operated electromagnetically. One of the common functions is to help in opening and closing of a laser shatter.
How do i disable the ERG valve?
If your EGR valve is vacuum operated, simply remove the vacuum hose from the valve.
Why are stomata and guard cells called turgor operated valves?

How does turgor pressure affects the opening and closing of stomata?
The stoma is "turgor operated valve". The opening and closing of stoma is regulated by the turgidity of guard cells. The stomata are open when the guard cells are turgid. On losing turgidity in guard cells, the stomata closes.
