What is the name of the process which sends the sucrose-water mixture from the phloem to the roots?

Question

BlackTom AI · Accepted Answer

The question asks for the name of the process that moves the sucrose-water mixture from the phloem to the roots.
Option a: Condensation. This term refers to a phase change from gas to liquid and is not related to transporting sap within plants, so it does not describe phloem transport.
Option b: Translocation. This is the correct concept for moving organic nutrients, such as sucrose dissolved in water, through the phloem from sources (like leaves) to sinks (such as roots or developing tissues). The sieve-tube elements in the phloem actively transport sugars, creating a pressure gradient that drives flow, which is precisely what translocation describes.
Option c: Transpiration. Transpiration involves water loss from leaves via stomata and the creation of a negative pressure that helps pull water upward in xylem, not the downward or lateral movement of photosynthates in phloem to roots. It does not describe the movement of sucrose in the phloem.
Option d: Evaporation. Evaporation is the process of a liquid turning into a vapor, typically at surfaces, and is not a transport mechanism for nutrients within the phloem network.
In summary, among the choices, translocation best names the active transport-based movement of sucrose-water through the phloem to various parts of the plant, including roots.
