Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
Red blood cells or RBC carry oxygen to the tissues in different parts of the body. Whiyte blood cells or WBC strengthen the defence mechanism of the body by generating antibodies. The primary difference between RBC and WBC lies in their functionality. While RBC act as carriers, WBC act as creators.
