Answer 2

ANSWER:

The companion cells are "specialized parenchyma cells" which are found in phloem and they are "closely associated" the special elements called sieve tubes.

EXPLANATION:

    These sieve tubes are long elongated structure which aids in migration of various biochemical substance like sugar, food etc. This biochemical substance reaches the shoot system and forms the best growth elements.

   These sieve tubes appear like roll stacks upon one another. Hence this structure helps in food transport.
