Summary Introduction

To write:The benefit to nonvascular plants having very thin rhizoids and leaf like structures

Introduction:Nonvascular plants constitute one of the four major classes of plants that arose from a single ancestor along with green algae. Nonvascular plants are small and allow easy movement of materials inside them.

Explanation of Solution

Mosses do not have true leaves; mosses have structures that are similar to leaves. Their photosynthetic, leaf like structures usually consist of a layer of cells that is only one cell thick. Mosses produce rootlike, multicellular rhizoids that anchor them to soil. Water and dissolved minerals can diffuse into a moss’s rhizoids.

Conclusion

Thus, it concludes that they have some tissue that carries water and food, these plants do not possess true vascular tissue.
