Phloem transports what
WebbPhloem tissue is composed of the sieve elements, companion cells or albuminous cells, phloem parenchyma and phloem fibres. Of them, the sieve elements and companion cells are important for transport. The sieve elements are anucleated, elongated living cells, through which transport actually takes place. They are connected end to end with … WebbActive transport loads the solutes from compassion cells into sieve tubes of the phloem at the source. 2. This lowers the water potential inside the sieve tubes so water enters the tubes by osmosis from the xylem and companion cells. 3. This creates a high pressure inside the sieve tubes at the source end of the phloem.
