Study Notes
Ferns and Non-Flowering Plants
- Ferns are green plants that grow in damp places and don't have flowers.
- They are one kind of non-flowering plant studied by botanists.
- Non-flowering plants have been around for millions of years and are some of the most ancient plants on Earth.
Non-Flowering Plants from Spores
- Ferns are non-flowering, evergreen plants that grow from spores instead of seeds.
- Spores are tiny cells created by the plant, released into the air or water, and can travel away from the original plant to create new cells.
- Ferns live in damp areas, unlike many other plants.
- Whisk ferns are similar to ferns, but they don't have real roots or leaves.
- Mosses are another non-flowering plant that grows from spores, with over 12,000 different kinds.
- Mosses like to grow in areas that are moist and shady, often covering the ground like a velvety rug.
- Club mosses have leaves shaped like needles and small leaves that make clusters in the shape of a cone, found mostly in tropical mountain areas.
- Liverworts and hornworts are spore-producing plants that grow on top of damp rocks and soil, and sometimes on tree trunks in damp areas.
- Hornworts are one of the oldest plants on Earth.
Horsetails and Gymnosperms
- Horsetails reproduce by spores and have no flowers, resembling a horse's tail.
- Gymnosperms are non-flowering plants that grow from seeds, including conifers, cycads, and ginkgo.
- Conifers have cones instead of flowers and needles instead of leaves.
- Cycads are a group of non-flowering plants that grow in tropical climates, with very thick stems and large, divided leaves.
- Cycads have been around over 200 million years, even older than dinosaurs.
- Ginkgo, also called the maidenhair tree, is another non-flowering plant that reproduces with seeds, with fossils of leaves dating back over 270 million years.
- Ginkgo trees can live for up to 3,000 years.
