Vedclass · Answer

(C) Phloem loading is the process of moving sugars from mesophyll cells into the sieve tube elements,which requires metabolic energy $(ATP)$ against the concentration gradient. Similarly,phloem unloading is the process of moving sugars from the sieve tube elements into the sink cells (where food is required),which also requires metabolic energy. Therefore,both processes are active.

Phloem loading and unloading processes are respectively:
