A fern is a type of plant that belongs to the group known as pteridophytes. Unlike flowering plants, ferns reproduce using spores instead of seeds. They typically have feathery, green leaves called fronds, which can vary in size and shape. Ferns thrive in moist, shaded environments, such as forests and wetlands. Ferns are ancient plants, with a history dating back over 300 million years. They play an important role in ecosystems by providing habitat and food for various animals. Additionally, ferns are often used in gardens and landscaping for their attractive foliage and ability to grow in low-light conditions.
