Question

Plzz tell me what is basic difference between interxylary and intraxylary phloem

Answer 1

You should know that Phloem first of all is external to the Xylem but exceptions are still there in dicot plants like Cucurbitaceae and in such cases where Phloem is growing internally to the xylem then that phloem is termed as Interaxylary Phloem.

And now in Interxylary Phloem they also exist in some dicot plants like Combretaceae and Acanthaceae but they are embedded to the secondary xylem and that is histologically (Structurally) distinct from Interaxylary.
