How are cell structures adapted to their functions?

WebFigure 6. Phloem is comprised of cells called sieve-tube elements. Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Lateral sieve areas connect the sieve-tube elements to the companion cells. Webphloem, plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant.
