Complete the analogy. Xylem : Water Transport :: Phloem : ______.
Food Transport
Xylem and phloem are the two vascular tissues of higher plants.
Xylem, made mainly of tracheids and vessels, conducts water and dissolved minerals upward from the roots to the leaves.
Phloem, made of sieve tubes and companion cells, transports the food (mainly sucrose) prepared in leaves during photosynthesis to all other parts of the plant, a process called translocation.
Mechanical strength is provided by sclerenchyma and, in part, xylem fibres; gas exchange occurs through stomata; protection from microbes is a role of the epidermis and bark.
Hence, phloem : food transport completes the analogy.
