Vedclass · Answer

(A) The provided diagram illustrates the pressure flow hypothesis (or mass flow hypothesis) for the translocation of sugars in plants.In this mechanism,sugars are loaded into the phloem at the source (e.g.,leaves),which creates a hypertonic condition,causing water to enter from the xylem by osmosis.This increases the turgor pressure in the phloem sieve tubes.In the diagram,$P$ points to the phloem tissue through which the sugar solution (phloem sap) is being transported from the source to the sink.Therefore,$P$ represents the phloem.

What is correct for $P$ in the given diagram representing the pressure flow hypothesis?
