Answer 2

Pteridophytes constitute the most primitive seedless vascular plants which reproduce by means of spores. They are the true land plants and are also called as ‘vascular cryptogams’.

Haeckel (1866) called these groups of plants as “Pteridophytes” because of their pinnate or feather-like fronds (leaves).

The Pteridophytes are known to be of high economic importance.
