Why is the phloem in a leaf important to the roots of a plant?
suter [353]

Answer:

The correct answer is A it transport the food generated by photosynthesis.

Explanation:

Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.

    Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.

  Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.

  Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
