${ \huge{ \fcolorbox{red}{pink}{❤Answer❤}}}$

Pressure flow or Mass flow Hypothesis

It is the most accepted mechanism for translocation of Sugars in higher plants. ... The glucose prepared in the leaves is converted into sugar. The sugar in the form of sucrose is moved into the companion cells and then into the living phloem sieve tube cells by active transport.

Answer 2

Answer:Food is synthesized in the green parts of a plant. The non-green parts are depended on the photosynthetic cells for nourishment. The food in the form of sucrose is transported by the vascular tissue phloem. Let us learn a bit more about phloem transport. The transportation occurs in the direction of the source to sink. Transport of organic solutes from one part of the plant to the other through phloem sieve tubes is called translocation of organic solvents.
