What is the difference between a vascular and a nonvascular plant? In your answer, discuss how water moves in each type of plant
Otrada [13]

Vascular plants have a vascular system while nonvascular plants have NO vascular system.

Explanation:

The vascular system is made of phloem – that transports food- and xylem- that transports water and minerals- in the higher plants. Examples of these higher plants are like trees and shrubs. These plants can take up water and nutrients from the soil and transport them up the plants to the leaves.

Lower plants have no vascular system (avascular). They mainly absorb food and water readily from their environment even through their leaves. This is why these plants are mainly found in humid areas like waterways, like canals. Examples of such lower plats are ferns and mosses.
