Post No. 32. Ferns
Ferns are a very ancient family of
plants and belongs to a group of vascular plants and unlike other vascular
plants they reproduce from spores in a stage called a gametophyte and have
neither seeds nor flowers. They are older than land animals and far older than the
dinosaurs. They were living on Earth for two hundred million years before the
flowering plants evolved.
Ferns first appear in the fossil
record about 360 million yeas ago in the late Devonian period, but many of the
current families and species did not appear until roughly 145 million years ago
in the early Cretaceous, after flowering plants came to dominate many
environments. Some ferns are used as
food, medicine, biofertilizer and ornamental plants and for remediating
contaminated soil. They have been the subject of research for their ability to
remove some chemical pollutants from the atmosphere. They play certain roles in
mythology and art. (Photo was taken from my visit to Fern Nature Center on April 7h, 2018)
