*       Transportation of Food and Hormones


The system, which is responsible for transportation of food and hormones is called phloem. Transportation of food is called translocation.


*         Phloem

Phloem is made up of living cells. Like xylem vessels its cells also joins end to end. But the cell walls at the joint are not broken completely although they form sieve plates, which have small holes in them to pass the food materials. Thus by connecting cells one by one, phloem tube is formed. Phloem tubes lie throughout the body. So food and hormones enter into it and reach to the required cells.
