Q. Which one of the following is a vascular cryptogam ?

AIPMTAIPMT 2009Plant Kingdom

Solution:

Pteridophytes are known as vascular cryptogams (Gk kryptos = hidden + gamos= wedded). They reproduce by spores rather than seeds. They are the first vascular land plant. The pteridophyte Equisetum belongs to the class sphenophtya. All vegetative parts of it possess vascular tissues (i.e. hadrome equivalent to xylem & leptome equivalent to phloem) organised in definite groups of steles.
