Write the paragraph in your own words about the ornamental plants called ferns.
Answers
A fern (Polypodiopsida or Polypodiophyta) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails or scouring rushes, whisk ferns, marattioid ferns, and ophioglossoid ferns.
Answer:
Ferns are most commonly grown ornamental plants and are because of their leaves, some examples are lasagne ferns staghorn ferns etc.ferns are the nonflowering vascular plant which has definite root, stems, and complex which reproduce by spores. They belong to the lower vascular plant division Pteridophyta, having leaves usually with branching vein systems; the young leaves usually unroll from a tight fiddlehead or crozier.
The number of fern species is about 9,000, but estimates have ranged to as high as 15,000, the number varying because certain groups are as yet poorly studied and because new species are still being found in unexplored tropical areas.The ferns constitute an ancient division of vascular plants,some of them as old as the Carboniferous Period (beginning about 359 million years ago) and perhaps older. Their type of life cycle, dependent upon spores for dispersal, long preceded the seed-plant life cycle.
