All organisms require a transportation system to distribute energy and nutrients while getting rid of unwanted materials or wastes. The human circulatory system is predominantly made up of the blood system. The plant transport system consists of the xylem and phloem.
The human circulatory system consists of the heart. The heart is responsible for pumping blood throughout the body. The pumping action creates the necessary pressure to ensure blood circulates in the body. Plants have no organs responsible for pumping water through the plant system. Plants rely on transpiration and osmosis to transport water from the roots to the leaves through the xylem. The system supports osmosis due to the differences in concentration from one cell to another.
The human circulatory system consists of vessels made up of living cells. The plant transportation system has vessels made up of dead and living cells. The phloem is made up of living cells. On the other hand, the xylem is composed of dead cells.
