Sieve Tube
Sugar-conducting tube of phloem; consists of stacked sieve elements.
Pressure Gradients
A physical quantity that represents the direction and rate at which pressure changes in a particular direction.
Evaporation
The process by which water changes from a liquid to a vapor or gas, a key component of the Earth's water cycle.

Final Answer :
C
Explanation :
Osmosis is the process responsible for creating large pressure gradients in sieve tube systems, as it involves the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, which can generate pressure.
