Osmosis is the movement of water across membranes to balance solute concentrations. Water diffuses from a solution that is hypotonic into a solution that is hypertonic

Turgor pressure is the hydrostatic pressure that increases as water enters plant cells.

The biosynthesis of gibberellins is under strict genetic, developmental, and environmental control, and numerous gibberellin-deficient mutants have been isolated. 

Mendel’s tall/dwarf alleles in peas are a famous example. Such mutants have been useful in elucidating the complex pathways of gibberellin biosynthesis.
