Overview. The differences between vascular and non-vascular plants are clear: vascular plants have a vascular system that transports water and minerals, and non-vascular plants don't. However, there are many important similarities between the two groups.
Vascular studies are a noninvasive (the skin is not pierced) procedure used to assess the blood flow in arteries and veins. A transducer (like a microphone) sends out ultrasonic sound waves at a frequency too high to be heard.
