TP Full Form

Turgor Pressure, also known as hydrostatic pressure, is usually caused by the osmotic water flow. The process takes place in plants, bacteria and fungi. It is also seen in protists as they have cell walls. Turgor Pressure is not observed in animal cells because there is no cell wall present. Thus, under high pressure, the cell will lyse. Other full forms of TP are Test Protocol in computer and networking category, Telephone pole in telecommunication category, Transfer Protocol in networking, Third Party in the software category, Triple Point in chemistry category, Test Point in electronics, Turbo Pump in space science category, Teaching Professional in job title category, Trade Police in stock exchange category, Tactical Points in military and defence category and beyond.

Turgor pressure in plant cells

Turgor pressure is regulated by the process of osmosis within the plant cells. This process is the main reason behind the expansion of cell walls during growth. Turgor pressure makes the cell rigid. The semipermeable membrane of the cell permits only a few solutes to move in and out of the cell. This mechanism regulates turgor pressure by maintaining a minimum pressure. Turgor pressure is the main factor for the transportation of nutrients in each and every part of the plant. In higher plants, this pressure is responsible for the growth of features like the tip of the roots and pollen tubes. The main role is in the dispersal process, flowering, reproductive organs of plants, seed dispersal, proper growth, maintaining turgidity, and stomata action. Not only in plants but turgor pressure is also observed in various other organisms and plays a major role in their development and movement.

How to measure Turgor Pressure?

There are multiple factors that are taken into consideration while measuring turgor pressure in plants. A cell that is fully turgid has a turgor pressure which is identical to the turgor pressure of a cell deficient in turgor, i.e. value near zero. Other factors that are taken into account are the protoplast solutes, cell transpiration rates, and tension in cell walls. Measurement of Turgor pressure varies with each method. The units for turgor pressure are bars, newtons per square metre, or MPa. the various methods for the measurement are potential water equation, pressure bomb technique, atomic force microscope, pressure probe, and micro-manipulation probe.  

Conclusion

TP, Turgor Pressure is something that makes the living tissues in plants rigid. If the turgor is lost due to the loss of water from cells, the flowers and leaves of the plant will wilt. It should be noted that turgor plays a very important role in the closing and opening of the stomata present in the leaves. Whether it is plants, fungi, protists, diatoms, or cyanobacteria, the role of turgor pressure is immense for the proper functioning of multiple processes. For instance, in cyanobacteria, the higher the pressure, the lower the capacity of the gas-vacuoles. It should be noted that many experiments took place to correlate turgor pressure and osmosis in prokaryotes.
