The sucrose move in source to sieve by active transport.
<h3>What is active transport?</h3>
Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element by osmosis, which increases the hydrostatic pressure.
