Question

Which instrument is used to measure root pressure?

Answer 1

Root pressure:

1. The sap rises through a plant stem to the leaves due to root pressure, which is the transverse osmotic pressure inside the cells of a root system.
2. Some vascular plants experience root pressure in the xylem when the soil moisture content is high, either at night or during periods of low transpiration.
3. A manometer is a device used to gauge plant root pressure.
4. Inches of water (in. H₂O), pounds per square inch (psi), and millibars (mbar) are common units used to measure the root pressure in the manometer.
