What are plants which live for several years called?
Plants are usually classified into three groups. Annuals - Plants that sprout from seed, go through all their growth stages and go to seed in the fall. Seed to seed, so to speak. An example would be Wheat, Barley, Corn or Oats! Bi-Annuals - These plants sprout from seed the first year and winter over as a Rosette and then in the spring of the second year they continue on through their growth stages to Seed. Sweet Clover, CurleyDock Plants, Garlic, and in some uses, Austrian Peas. Perrenials - are plants that sprout from seed, grow to maturity and produce seed from the first year on through several years. Your lawn grass would make a good example or an Elm Tree.

seed ferns
Are gymnosperm the oldest type of seed plant?
Seed ferns in Gymnosperms were the oldest seed plants but none of them is in living condition today.
What ancient plants were called seed ferns?
The plants known as seed ferns were ancient, fern-like plants that produced seeds instead of spores for reproduction. They thrived during the Paleozoic and Mesozoic eras, with fossil evidence indicating they were widespread and diverse. Despite their name, seed ferns were not true ferns, but early gymnosperms that eventually gave rise to modern seed plants.
Did gymnosperms evolve before angiosperms?
Yes, gymnosperms evolved before angiosperms. Gymnosperms, characterized by naked seeds, are an ancient group of seed-producing plants that first appeared in the Paleozoic era. Angiosperms, which have enclosed seeds within ovaries (fruits), evolved later during the Mesozoic era.
What were the dominant plant form during the Paleozoic Era?
During the Paleozoic Era, dominant plant forms included ferns, horsetails, and early seed plants like conifers and cycads. These plants were the main producers in terrestrial ecosystems, contributing to the diversity and abundance of life during this time period.
What animals and plants flourished during paleozoic and mesozoic period?
In the Paleozoic period, animals such as trilobites, brachiopods, ammonites, and early vertebrates flourished. Plants included ferns, horsetails, and early seed plants. During the Mesozoic period, dinosaurs, marine reptiles like ichthyosaurs and plesiosaurs, as well as early mammals and birds were prevalent. Plants such as conifers, cycads, and ginkgoes thrived during this time.
Did non-seed plants evolve from seed plants?
