Question 5 Which molecular forces are more important for phloem transport? Select all that apply O Cohesion of water molecules to one another Adhesion of water molecules to other surfaces O Turgor pressure Changes in tonicity Question 6 During phloem transport, which of the following occur at, or close to the source? Select all that apply Sugars move out of sieve tubes by active transport Sugars move into sieve tubes by active transport Water moves from the xylem into the sieve tubes Water moves from phloem into the xylem Solution in sieve tubes becomes hypertonic n Solution in sieve tubes becomes hypotonic

Explanation / Answer

Ans 5 : turgor pressure

The transport through phloem is a bulk flow , which is pressure -driven. It is responsible for the transport of sugars from source to sink. The water passively flows inside due to higher solute concentration , which causes turgor pressure to push the molecule towards the sink.
