Main function – upwards water transport. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.
Similarities: both have cell membranes, DNA, cytoplasm
Differences: only eukaryotic cells have mitochondria/chloroplasts, nuclear membrane, endoplasmic reticulum, DNA in a chromosome
