"(c) Gravitation
Cell water potential depends on three major factors which are solute concentration, water pressure, and gravity.
The water potential Ψ can be represented as
Ψ = Ψ_s + Ψ_p + Ψ_g
Where Ψ_s = solute potential; Ψ_p = pressure potential and Ψ_g = gravitational potential.
Solute potential is said to represent the effect of dissolved solutes on the cell water potential.
""Pressure potential"" represents the ""effect of hydrostatic pressure"" on the cell water potential.
Gravitational potential represents the effect of gravity on the cell water potential. "
