Question

What is the role of water pressure?

what role does hydrostatic pressure play in maintaining a plants posture?

What human structure depends on hydrostatic pressure to maintain its shape and to fulfill its special purpose?

Answer 1

Plant cell growth depends on a delicate balance between an inner drive—the hydrostatic pressure known as turgor pressure and an outer restraint, the polymeric wall that surrounds a cell. One significant function of the turgor pressure is to promote cell volume expansion.

Turgor pressure is not observed in animal cells because they lack a cell wall. In organisms with cell walls, the cell wall prevents the cell from lysing from high-pressure values.

Hydrostatic pressure in human physiology is the force generated by the pressure of fluid within or outside of capillary on the capillary wall.Hydrostatic pressure in blood vessels is caused by the weight of the blood above it in the vessels.

The normal hydrostatic pressure in the capillary bed is controlled by local myogenic, neurogenic, and humoral modulation of the arterial and venous resistances.
