Pterophytes typically grow along stream beds or in damp forests.
cryptogams r divided into three plants.thallaphytes, bryophytes and pterophytes . thallaphytes and bryophytes show the absense of true leaves,seeds and stems. pterophytes r the most complex cryptogams which show the presese of true leaves,stems and seeds but they dont have flowers.all types of ferns are pterophytes.

Yes, pterophytes have fronds, which are large, complex leaves that typically have a prominent midrib and branching veins. These fronds are the primary photosynthetic organs of pterophytes and are characteristic of this group of plants.
1.5 billion years ago (bya)
The first fossils of pterophytes, also known as ferns, are known from the early Carboniferous, around 350 million years ago. The first modern families of ferns are known to have appeared during the Triassic.
400 Million years ago hope this helps :D
you have to do this as a science project for bio
It's because pterophytes are vascular plants that contains vascular tissues which support growth. Bryophytes are nonvascular plants, they don't have vascular tissues that's why it doesn't grow too large. ! Vanessa =D
There might be many diffrent reasons but if you are still growing than it might be a growing pain or cramps.
Yes, pterophytes, which include ferns and their relatives, produce spores as part of their reproductive cycle. They have a dominant sporophyte generation that produces spores in structures called sporangia, typically located on the undersides of their fronds. These spores can then disperse and grow into a separate gametophyte generation, completing the life cycle.
Horsetails are not a seed plant because they are a seedless vascular plant and fall into the catergory pterophytes. According to the diversity of plants Seed Plants evolved in about 360 mya after Pterophytes (about 420 mya) . So in order for a plant to be a seed plant it should fall into the plant group of either Gymnosperm or Angiosperm.
