Transprtation Of Food in Plants

Food (sugars) is made in the special green cells (mesophyll cells) of the leaves, from water and carbon dioxide. Water is brought to the leaf by xylem and carbon dioxide enters through stomata.
Sugars from mesophyll cells ente the phloem cells of the leaf veins. From here the sugars may be transported by phloem forms to all other parts of the plants where these are to be utilized or stored.  Like xylem, phloem forms continuous pathway throughout the plants.

Phloem runs from the leaves to every other parts of the plants. The food may be transported by phloem in any direction within the plants. It may be carried upward, downward and even laterally
