This video tutorial explains the structure and function of phloem in plants. It covers the role of phloem in transporting assimilates like sugars and amino acids from leaves to other parts of the plant. The video contrasts phloem with xylem, highlighting that phloem is a living tissue. It details the structure of sieve tube elements and companion cells, explaining their roles in phloem function. The video also describes the support structures within phloem, such as fibers and sclerods, which provide structural integrity.
