What are two different ways a plant could control turgor pressure, a name for internal water potential within its cells? is this a sufficient definition for turgor pressure?

Turgor pressure is defined as the pressure exerted by the fluid in the cell, which presses cell membrane against the cell wall. The turgor pressure in plants is generated through osmotic inflow of water into cells.  

The plants control turgor pressure in two ways:

1. The plants actively transport the proteins to inside and outside of the cells to maintain the pressure exerted by the fluids.  

2. The cells increase or decrease the solute concentration inside the cells. The leaves perform evaporation changing the water concentration levels in the plant.

Therefore, the turgor pressure is pressure exerted by plasma membrane over cell wall. It can be explained as the cytoplasmic membrane's pressure over the cell wall that impact water potential.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
