Detailed explanation-1: -The complex tissue made up of pipe-like specialized cells that help in transporting food from leaves to other parts of plants is called phloem.

Detailed explanation-2: -Sieve tubes are elongated tubular conducting channels of phloem through which food is transported. The contents of phloem can move in the upward as well as in the downward direction. Therefore, they form two-way traffic in plants.

Detailed explanation-3: -Plants have a pipe like vessels made of special cells known as vascular tissues which transport minerals, water, and food synthesized by leaves. These vascular tissues are xylem and phloem. Xylem transports water and minerals from roots to leaves through the stems and branches.

Detailed explanation-4: -Xylem and phloem are cells involved in the transport of water and other substances in plants.

Detailed explanation-5: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
