The component that is found in both vascular and nonvascular plants is chlorophyll. Chlorophyll is the green pigment that is essential for photosynthesis, allowing plants to capture light energy and convert it into chemical energy, and it is present in a variety of plant types, including both vascular plants (like trees and flowering plants) and nonvascular plants (like mosses and liverworts).
Leaves, stems, and roots are typically associated with vascular plants, as nonvascular plants do not have these structures in the same way.
