How do phloem vessels differ from xylem vessels in terms of the cells that form them?
Which of the following is true about the vessels that transport substances in a plant?
Phloem vessels are made up of columns of cells with small holes in their end walls. Why does this arrangement allow food products to be transported throughout the plant?
