Answer:
Companion cells are the specialized parenchyma cells associated with the sieve tube elements of phloem. They help in the development and function of a sieve-tube element. Companion cells probably provide ATP, proteins, and other substances to the sieve-tube elements, whose cytoplasm lacks many structures necessary for cell maintenance. Companion cells move sugars and amino acids into and out of the sieve elements.
