What is the difference between pteridophytes and gymnosperms?

What is the living fossil among the pteridophytes?
equisetum
Why are angiosperms closely related to pteridophytes?
gymnosperms
Do pteridophytes have flowers?
No, pteridophytes do not have flowers. They are non-flowering vascular plants that reproduce via spores instead of seeds, and they include ferns, horsetails, and clubmosses. Pteridophytes have distinct structures like fronds and strobili but lack the reproductive structures associated with flowering plants.

What are some characteristics of pteridophytes?
Pteridophytes are non-flowering vascular plants that reproduce by spores. They have well-developed roots, stems, and leaves, with xylem and phloem for nutrient transport. Most pteridophytes require moist environments for growth and reproduction.

No, pteridophytes do not have seeds. They reproduce via spores, which are released from structures called sporangia on the underside of their leaves. These spores develop into gametophytes that produce eggs and sperm for fertilization.
What is botanical term for plant that reproduces by spores?
ferns PTERIDOPHYTES
