Ferns: Structure, Function, and Adaptations

Ferns are ancient plants that have thrived for over 300 million years across diverse climates. They are characterized by their large fronds, which help them capture sunlight in low-light environments. Unlike flowering plants, ferns reproduce through spores. They exhibit a wide range of forms and sizes, from small ground ferns to towering tree ferns. Ferns also display various frond shapes and can be epiphytic, growing on other plants. They play crucial roles in ecosystems by stabilizing soil, providing habitats, and serving as food sources for animals.
