The primary difference is the driving mechanism. In plants it is one-way capillary action in small tubes. In humans it is pressure drop within a closed-loop circuit.

Explanation:

Plants obtain liquids and move nutrients and wastes through the system from their roots to their leaves by the capillary action of small tubes within the plant.

Part of the human circulatory system may include localized transport by capillary action and osmosis as well, but the primary driving mechanism is the pressurization of the blood stream by the heart, pushing it through the venous system to the low-pressure inlet side of the heart in a continuous recycling loop.
