Summary Introduction

Introduction :

Pteridophytes and bryophytes are plants without seeds and flowers. In contrast, ferns are highly evolved plants since they have distinct genuine leaves, stems, and roots on their plant bodies. Mosses are little bryophytes that resemble lichens. Additionally, as they are photosynthetic plants, they are crucial in maintaining environmental balance. They serve as an essential buffer system for other plants and are excellent indicators of the condition of the ecosystem.
