Pteridophytes are vascular plants that reproduce via spores and include clubmosses, horsetails, and ferns, with around 13,000 species worldwide. They are commonly grown for their decorative foliage and thrive in damp, humid environments. Ornamental pteridophytes not only enhance aesthetics but also improve air quality by removing indoor pollutants.

for us;
 –Many ornamental plants are chosen
because they appeal to the sence of smell,in
addition to their visual appeal.
-Without plants we couldnot have
clean air to breath because plant create oxygen
during photosynthesis.
 Keeping ornamental pteridophytes has been
shown to improove the air quality to remove
the house air pollution like tobacco & other.

29.  Ornamental pteridophytes are used in landscapes
and throughout the home to beautify the
surroundings.
