WebbIt conducts food materials to various parts of the plant. The phloem elements which are formed from the procambium of apical meristem are called primary phloem. The phloem elements which are produced by the vascular cambium are called secondary phloem. Phloem Like xylem, phloem is also a complex tissue. WebbPhloem structure function In the phloem, tubular cells assemble into so-called sieve tubes which form a continuous microfluidics network. In this network, the products of photosynthesis are distributed throughout the plant body from sources (mature leaves) to sinks (young leaves, roots, fruits etc.).
