Osmosis is the phenomenon of water flow through a semi-permeable membrane from high watre potential to low water potential. However the flow may be stopped, or even reversed by applying external pressure on the volume of higher concentration. In such a case the phenomenon is called reverse osmosis.
Tonicity is measure of the effective of osmotic pressure. Osmosis is the minimum pressure which needs to be applied to a solution.

Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process. Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the osmosis process. It is comparing a zero additional pressure with any positive additional pressure thus of cause reverse osmosis require more pressure.
Tonicity is measure of the effective of osmotic pressure. Osmosis is the minimum pressure which needs to be applied to a solution.
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.

applying a pressure equal to the osmotic pressure on the more concentrated solution side.
The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
The osmotic pressure. This is the pressure which would have to be applied to a solution to stop water entering if it was separated from pure water by a semipermeable membrane.
is the force responsible for moving fluid across capillary walls. It is the difference between net hydrostatic pressure and net osmotic pressure. NFP= Net hydrostatic pressure - net osmotic pressure
a pressure greater than the osmotic pressure is applied in the opposite direction osmosis is occurring.
NaCl is generally added to the nutrient media for maintaining the Osmotic pressure. Maintaining osmotic pressure is important, because, increase or decrease in the osmotic pressure leads to cell burst or death due to the effect of osmosis. So, maintaining the osmotic pressure is done by adding correct amount of NaCl.
