Well, plants have a vascular system whereas animals have a circulatory system. They both utilize tube structures that transport water and nutrients to the cells and different parts of the organism. Plants have xylem and phloem and animals have veins and arteries. An animal's circulatory system is driven by a pump, via the heart. A plant's vascular system is driven simply by gravity and the many useful properties of water. Plants have water-based solutions within their vascular systems and animals have mainly white and red blood cells within their circulatory systems.
