What is the major difference between fern with the fern allies?
The major difference between ferns and fern allies is their reproductive structures. Ferns reproduce through spores produced in clusters called sori on the underside of their fronds, while fern allies reproduce through strobili or cones. Additionally, ferns have true roots, stems, and leaves, whereas fern allies lack true roots and leaves.
What evidence suggests that cycads and ginkgos were once more widespread then they are now?
Fossils of cycads and ginkgos have been found in regions where they are no longer naturally occurring, indicating they were once more widespread. Additionally, molecular studies have shown genetic relationships between present-day species of cycads and ginkgos that are separated by large geographical distances, suggesting a broader historical distribution.
What is the difference between the toadstool and the fern in terms of their nutrition?
Toadstools are fungi, which obtain nutrition by absorbing nutrients from their surroundings through their mycelium. Ferns are plants that photosynthesize to create their own food by converting sunlight into energy. Therefore, toadstools are heterotrophs, while ferns are autotrophs.
What are fronds?
Fronds are the large, leaf-like structures of ferns and palm trees that are typically divided into smaller segments or leaflets. They are important for photosynthesis and can vary in size and shape depending on the plant species.
Which of these is not a gymnosperm Fern Cycad Pine or Ginkgo?
Fern is not a gymnosperm. Ferns are a group of plants that belong to the division Pteridophyta, whereas gymnosperms include cycads, pines, and ginkgoes. Gymnosperms are seed-producing plants with "naked seeds" that are not enclosed within a fruit.
Is cycads are ferns?
No, cycads are not ferns; they belong to a different group of plants. Cycads are gymnosperms, which means they produce seeds and have a distinct reproductive structure, while ferns are vascular plants that reproduce via spores and do not produce seeds. Although both cycads and ferns are ancient plant lineages, they have different biological characteristics and evolutionary histories.
what are plants that have a thin stalk with tiny leaflike parts between ferns, conifers, mosses, cycads?
archegonium
What are fronds called?
The compound large leaves of ferns and Cycads are called fronds.
What is the difference between ferns and trees?
the spelling
What plant was there when there were dinosaurs?
Ginko trees, ferns, cycads, conifers, and during the Cretaceous, flowering plants.
What is the difference between cycadopsida and ferns?
cycopsida is palm like structure
What did stegosaurasus eat?
Stegosauruses were herbivores, and therefore ate plants such as mosses, ferns, horsetails, cycads and conifers or fruits.
What fossils can be found for the Jurassic period?
Fossils from the Jurassic period include dinosaurs such as Stegosaurus and Allosaurus, marine reptiles like Ichthyosaurs and Plesiosaurs, and early mammals and birds. Plant fossils like ferns, cycads, and conifers are also common from this period.
What is the difference between mosses and ferns and how does this difference effect their life cycle?
mosses are nonvascular but fern are vascular
What is the difference between pteridophytes and gymnosperms?
Stem of gymnosperm is aerial.Stem of pteridophytes are mostly underground.Tree Ferns have long aerial stems but these are Pteridophytes. The real difference is that gymnosperms bear seeds pteridophytes are without seeds.
What were the landforms for the Jurassic Period?
The Jurassic Period had forests of ferns, cycads, and coniferns, along with a warm, moist, tropical climate.
What kinds of plants did the Stegosaurus eat?
Ferns, shrubs, grass, moss, rose hips, cycads, monkey puzzle plants and fruits.
