The veins, arteries, and capillaries. Xylem and phloem are transport tissues in plants similar to the veins, arteries and capillaries in animals The xylem tissue transports water from roots to shoots and leaves of plants. But unlike plants, the veins and arteries carry oxygenated and deoxygenated blood to and out of the heart. While phloem transports soluble organic compounds made during photosynthesis. The phloem is the exact replica of capillaries because they carry nutrients and oxygen to tissues and remove waste products.
