All organisms require food and water for their survival. Transportation is the process of transporting water,food and minerals to the different parts of the plant body. Xylem, transports water from the roots to all parts of the plant through root hairs. Raw materials such as carbon dioxide, water and other minerals are used to prepare food in the presence of sunlight through photosynthesis.This food is then transported to all parts of the plant by the Phloem. .
